Answer:
0.20
Explanation:
The narrow-sense heritability, denoted by h², refers to the ratio of additive genetic variance (Va) to the total phenotypic variance (Vp).
Mathematically, it can be written as:
h² = V(A)/V(P)
Where;
V(A) = additive genetic variance
V(P) = total phenotypic variance
V(A) = V(P) × h²
Based on the information provided in the question, V(P) = 0.5, h² = 0.4
V(A) = 0.5 × 0.4
V(A) = 0.20
The additive genetic variance (VA) for ear length in these rabbits is 0.2.

strands.
2. DNA unwinds.
3. DNA coils up.
4. The hydrogen bonds are broken between the nitrogenous bases.
Answer: The answer is C.
Explanation: I jus got done taking the test. Also remember the first start is breakin through and tearing apart the hydrogen base bonds, then they’re glued so they do not coil back up.
The correct order of replication are DNA unwinds then the The hydrogen bonds are broken between the nitrogenous bases, and Appropriate free nucleotides are added to the complementary DNA strands. DNA coils up.
What is DNA replication?DNA replication is the process through which cells make copies of the genome's DNA. A cell must first copy (or duplicate) its entire genome before it can divide, ensuring that each daughter cell has a complete genome upon division.
One of DNA's most astounding tricks is likely DNA replication. If you stop to think about it, every cell has all the DNA required to create every other cell.
Therefore, DNA is a molecule that can be copied to create almost exact duplicates of itself. Considering that there are almost three billion base pairs in DNA that need to be copied, this is even more astounding. DNA polymerases, which are molecules dedicated solely to copying DNA, are also used in replication.
Therefore, The correct order of replication are DNA unwinds then the The hydrogen bonds are broken between the nitrogenous bases, and Appropriate free nucleotides are added to the complementary DNA strands. DNA coils up.

Conjecture what would happen if a primate infant did not possess your chosen primate hand features. Answer this question with the survivability of the infant in mind
Answer:
Where the primate infant did not possess primate hand features, it will not be able to feed itself. For example, a monkey cannot survive without its grasping hands. It uses them to feed itself. So if an infant monkey does not possess the primate hand features, its survival will be greatly hampered.
Explanation:
Ordinarily, primates (including humans) have five fingers on each of their hands and five toes on their feet. Most primate species have fingernails instead of claws, and they have touch-sensitive pads on each of their digits. The hands and feet of all primates are designed for grasping, with the only exceptions being humans. Human beings feature deep perceptions that differentiate them from other primates.

What is the group number for Calcium and does it have cations or anions???
Answer:
the group number is 2
Explanation:
it is cations
Answer:
A Calcium is in group 2
explanation:
because it forms only the Ca 2+ ion. B Dihydrogen phosphate is the H 2PO 4 − ion (Table 2.4 "Common Polyatomic Ions and Their Names"). Two H 2PO 4 − ions are needed to balance the positive charge on Ca 2+, to give Ca(H 2PO 4) 2.
Why is a fern a vascular plant
Answer:
Ferns are seedless, vascular plants. They contain two types of vascular tissue that are needed to move substances throughout the plant. Evolutionarily, this addition of vascular tissue to plants is what allowed ferns to grow up and out rather than just spreading along the ground.

If sunlight and a radio wave are both traveling through water, compare the speed of each wave. Explain how you know.
Answer:
Speed of both will be decreases when they travel through the medium of water.
Explanation:
Both sunlight and radio wave has the same speed in vacuum but both speed will be decreases when they travel through the medium of water because the consistency of water is more than air which make hard to travel for sunlight and radio wave. The speed of sunlight is slightly decreases but the radio wave can't go too far in the water and finally stops so we can say that sunlight can travel through water but radio wave none.
Can I pls get help !!
Answer:
I am not certain but I think it's DNA to RNA to protein may be wrong but I think that's the answer
Answer:
C. DNA to RNA to protein
Explanation:
This question is asking about protein synthesis. Let’s analyze the process.
It begins in the nucleus. DNA is too large to pass through the nucleus, so something has to be done. DNA is “unzipped” using an enzyme called polymerase. Nucleotides attach to create a new strand of messenger RNA, in the process of transcription. The mRNA is small enough to pass through the nucleus.
So the first step is DNA to RNA.
Then, the mRNA makes it way to the ribosome. Here, translation takes place. Transfer RNA reads the mRNA and matches a set of three bases (codon) to an anticodon. The tRNA attaches amino acids based on the codon. A protein will form and bend into a specific shape.
So, the next step is RNA to protein.
Overall, the process is DNA to RNA to protein. Choice C is correct.

Why could organisms that use a K-selected life strategy be more at risk when environmental conditions change?
Answer:
K-selection organisms have the maximum chance of surviving in the surrounding where the number of organisms is near the carrying capacity, however, the lack of offspring makes them endangered species.
Explanation:
K-species can give the offspring with the great possibility of surviving until mature.
K-selection is the most frequent in big animals, that have a long life span, and many generations that meet. K-selection organisms give less offspring but with a stronger organism.
However, these organisms are more endangered, as they tend to have fewer offspring, so their populations cannot recover as quickly from disorders such as excessive hunting or fire.

When a bee visits a flower for sweet, sweet nectar, the plant's gametes are also spread to anoher plant. What kind of symbiotic relationship is this?
Answer:
Mutualism
Explanation:
Mutualism is a type of symbiotic relationship in which the two species of organisms involved benefit from one another i.e. the actions of one benefits the other.
In this question, a bee is said to visit a flower for sweet nectar, however, in the process of feeding on the flowers nectar, the plant's gametes are also spread to another plant by the bee. This is a type of MUTUALISTIC RELATIONSHIP because the plant is beneficial to the bee by providing food (nectar) while the bee also helps the plant by helping it pollinate.

Non-steroidal anti-inflammatory drugs (NSAIDS) block the actions of the COX enzymes and their production of eicosanoids from ___.
Answer:
Arachidonic acids
Explanation:
Non-steroidal anti-inflammatory drugs (NSAIDs) are drugs used due to their analgesic, anti-inflammatory effects.
It inhibit cyclooxygenase (COX) enzyme that takes part in the biosynthesis of prostaglandins (PGs) and thromboxane (TX) and the production of eicosanoids.
Eicosanoids are made by the enzymatic or non-enzymatic oxidation of arachidonic acid or from other polyunsaturated fatty acids (PUFAs) that are close to arachidonic acid which are 20 carbon units in length.
They are important cell signaling molecules that inhibit inflammation, allergy, fever,regulate abortion of pregnancy and normal childbirth, regulating cell growth.

The genome of D. melanogaster consists of approximately 1.7 * 108 base pairs. DNA synthesis occurs at a rate of 30 base pairs per second. In the early embryo, the entire genome is repli- cated in five minutes. How many bidirectional origins of synthesis are required to accomplish this feat?
Answer:
9444.44 origins
Explanation:
From the given information:
The genome of D. melanogaster = 1.7 × 10⁸
1 sec = 30 base pair
1 min = 1800bp i.e. (30 × 60 = 1800)
5 Min = 9000 bp i.e. (1800 × 5 = 9000)
Suppose there was a single bidirectional origin, then the process would proceed as:
= 1.7 × 10⁸ / 2*(1 / sec / 30 bp)
= 2833333.333
SInce it only takes 300 seconds in ( 5 minutes), then:
There should be 2833333.333/300 = 9444.44 origins to accomplish suh feat.

Does the hallux (big toe) of Carpolestes have more synapomorphic features shared with the euprimate, or more symplesiomorphic features shared with the tree shrew? Provide at least one feature you used to make your decision.
Note: You will find the missing image needed to answer the question in the attached files.
Answer:
The hallux (big toe) of Carpolestes has synapomorphic features shared with the euprimate.The nail on the distal phalange is an example of a synapomorphic feature.Explanation:
The symplesiomorphic features are those shared by two or more organisms that inherited it from a common ancestor, but this trait is older in relation to those traits exhibited in other descendants of that same ancestor.The synapomorphic features are those shared by two or more organisms that inherited it from a common ancestor, and which evolved for the first time in it.There are more synapomorphic features shared with the euprimates. The nail on the distal phalange of the big toe and euprimates might be considered as a synapomorphic feature. It is quite different from the same nail of the tree shrew.
Muscular dystrophy is a neuromuscular disease that weakens a person's muscles. Which main body systems would be involved in this disease? (1 point)
Item 2
nervous, muscular, and respiratory
Item 3
nervous, muscular, and vascular
Item 4
nervous, muscular, and urinary
Item 5
nervous, muscular, and skeletal
Answer:
nervous, muscular, and vascular
Explanation:
Muscular dystrophy (MD) is a group of inherited genetic conditions that cause progressive weakness and the loss of muscle mass. MD is caused by mutations in genes responsible for muscle function. MD not only leads to problems in the muscular system but also may cause disorders of the central nervous system and the circulatory system (especially the heart). For example, Becker muscular dystrophy is a condition associated with arrhythmias and cardiomyopathies. Moreover, MD may lead to vision and speech problems, and result in irreversible structural brain changes.
Answer:
Nervous, muscular and skeletal
Explanation:
Describe the difference between normal vision and colorblindness. Do individuals with red/green colorblindness have difficulty seeing at night? Why or why not?
Answer:
Color vision is possible due to photoreceptors in the retina of the eye known as cones. These cones have light-sensitive pigments that enable us to recognize color. Found in the macula (the central part of the retina), each cone is sensitive to either red, green or blue light (long, medium or short wavelengths). The cones recognize these lights based on their wavelengths. Normally, the pigments inside the cones register different colors and send that information through the optic nerve to the brain. This enables us to distinguish countless shades of color. But if the cones don't have one or more light-sensitive pigments, they will be unable to see all colors.
Most people with color vision deficiency can see colors. The most common form of color deficiency is red-green. This does not mean that people with this deficiency cannot see these colors altogether, they simply have a harder time differentiating between them, which can depend on the darkness or lightness of the colors.
Another form of color deficiency is blue-yellow. This is a rarer and more severe form of color vision loss than just red-green deficiency because people with blue-yellow deficiency frequently have red-green blindness, too. In both cases, people with color-vision deficiency often see neutral or gray areas where color should appear.
People who are totally color deficient, a condition called achromatopsia, can only see things as black and white or in shades of gray. Color vision deficiency can range from mild to severe, depending on the cause. It affects both eyes if it is inherited and usually just one if it is caused by injury or illness.

A small, leafy branch is cut from a tree. After some hours, the stem of the branch remains firm . Suggest an explanation for this
Answer:
Explanation:
When a branch is detached from a tree, water is being lost through the porous open area. After some time, a callous formation of new tissues starts to appear on the open surface to terminate further loss of water. The osmotic pressure in the leaves gets reduced as they no longer contain enough water, while the stem is being filled with water due to the network of capillaries.
