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.
"The gross primary productivity of a meadow in southeastern Kansas is found to be 38,000 kcal/m 2 . Respiration which is measured by the amount of CO 2 released is 13,500 kcal/m 2 , what is the net primary productivity for this ecosystem, in kcal/m 2 per year
Answer:
Net primary productivity = 24,500 kcal/m²
Explanation:
Given:
Gross primary productivity = 38,000 kcal/m²
Respiration amount = 13,500 kcal/m²
Find:
Net primary productivity
Computation:
Net primary productivity = Gross primary productivity - Respiration amount
Net primary productivity = 38,000 - 13,500
Net primary productivity = 24,500 kcal/m²

2. What fluvial landform is A?
Answer:
The landform marked with A is an ox-bow lake.
Explanation:
In the image, we can see a river and another fluvial landform right next to it. The river is meandering, moving through the plain in a zig-zag manner. The landform next to it has a half-circular shape, and it seems as it has been attached to the river until recently. In fact, the landform next to the river has been a part of the river until recently, but because of moving too far away from the base it became detached.
The landform in question is an ox-bow lake. This is a lake that has a short lifespan, and it usually has a half-circular shape, being just a few meters away from the river from which it formed. Initially, the ox-bow lake was actually part of the river and its meandering, but as the erosion was moving the water further and further away from the base of the river bed, the water was moving harder and harder, so naturally, the water moves in a direction where it is easier to do so. Little by little, the river starts to move in another direction, closer to its base, and the part of the meander that went too far away gets detached, thus forming an ox-bow lake.
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.

Explanation:
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.

Compare and contrast an ecosystem driven by photosynthesis to an ecosystem driven by chemosynthesis
Answer:
Chemosynthesis gets its energy from oxidation of inorganic substance, photosynthesis gets its energy from light.
Chemosynthesis could occur just about anywhere there are enough suitable chemicals to oxidize [metabolize], while photosynthesis could occur only when there is sufficient light.
Higher energy contained in the sugar molecules produced by photosynthesis comes from
A. light.
B. carbon dioxide molecules.
C. ATP. .
D. water molecules.
Answer:
A. light.
Explanation:
Photosynthesis is the process whereby green plants manufacture their food in form of sugars (glucose) in the presence of sunlight as energy source. The process combines carbon dioxide and water to produce glucose and oxygen, with light source from the sun providing the required energy.
High energy is stored in the bonds of the glucose molecule produced (C6H12O6). This energy emanates from the SUN (solar energy), which the photosynthetic process cannot so without.

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.
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:
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.
Where does the energy go after it reaches the top predators?
Answer:
Energy that is not used in an ecosystem is eventually lost as heat. Energy and nutrients are passed around through the food chain, when one organism eats another organism. In each case, energy is passed on from one trophic level to the next trophic level and each time some energy is lost as heat into the environment.

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.

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.
