An organism has the following genotype: AABb. What type of gametes can be produced, and in what proportions ?
Answer:
AB Ab AB Ab
AB 50 Ab 50
Explanation:
The organism can produce TWO types of gametes: AB and Ab. Supposing these genes are unlinked, the proportion of gametes will be 1/2 (50 percent of each gamete).
Meiosis is a reductional cell division where the resulting daughter cells (gametes) where chromosome number is divided into half, thereby producing haploid gametes in a diploid individual.The law of segregation (also called Mendel's First Law) indicates that during meiosis, alleles separate.In consequence, after meiosis, each gamete receives only one allele for a given trait.In conclusion, the organism can produce TWO types of gametes: AB and Ab. Supposing these genes are unlinked, the proportion of gametes will be 1/2 (50 percent of each gamete).

A sugarcane plant with yellow pollen and wavy leaves is crossed with a plant with yellow pollen and smooth leaves. Seed are collected and germinated. The following results are obtained in the progeny:
153 yellow pollen, wavy leaves
145 yellow pollen, smooth leaves
48 white pollen, wavy leaves
51 white pollen, smooth leaves
a. For each locus (trait): Assign appropriate symbols for the alleles of the genes, indicate the dominance interaction between the two alleles, and give all possible genotypes and their associated phenotypes
b. Give the genotypes of the parents of this cross.
c. Give the expected genotypic and phenotypic ratios of the progeny of this cross.
Answer:
a.
i) Y and y represent Yellow and white alleles for the pollen color gene; where Y (yellow) is dominant over y (white).
ii) W and w represent wavy and smooth alleles respectively for the leaf texture gene. W (wavy) is dominant over w (smooth).
YYWW, YyWW, YyWw, YYWw- yellow, wavy phenotype
YYww, Yyww- yellow, smooth phenotype
yyWW, yyWw- white, wavy phenotype
yyww- white, smooth phenotype
b) yellow pollen and wavy leaves (YyWw) × yellow pollen and smooth leaves (Yyww)
c) Expected genotypic and phenotypic ratio of progeny: 3:3:1:1
Explanation:
This question involves two distinct genes; one coding for pollen color and the other for leaf texture. Let Y and y represent Yellow and white alleles respectively for the pollen color gene; where Y (yellow) is dominant over y (white) while W and w represent wavy and smooth alleles respectively for the leaf texture gene; W allele (wavy) is dominant over w allele (smooth).
Next, we convert the progeny number to phenotypic ratio by dividing each number by the smallest number (48)
yellow pollen, wavy leaves= 153/48 =3.18
yellow pollen, smooth leaves= 145/48= 3.02
white pollen, wavy leaves= 48/48= 1
white pollen, smooth leaves= 51/48= 1.06
Approximately, the phenotypic ratio of the progeny is 3:3:1:1
According to the question, a parent with with yellow pollen and wavy leaves will have genotype YyWw because white pollen (w) and smooth leaf (s) was produced in the progeny. Also, the other parent with yellow pollen and smooth leaves will have genotype: Yyww. In a cross between these two parents i.e. YyWw × Yyww, the following gametes will be produced:
YyWw- YW, Yw, yW, yw
Yyww- Yw, Yw, yw, yw
Using these gametes in a punnet square (see attachment), the following 16 offsprings will be produced in a ratio 3:3:1:1
yellow pollen, wavy leaves (Y_W_) 6
yellow pollen, smooth leaves (Y_ww) 6
white pollen, wavy leaves (yyW_) 2
white pollen, smooth leaves (yyww) 2

Answer:
No
Explanation:
They have different division rates as some are more important for the body's health than others.
Ex) Skin cells repair very fast as they are on the exterior of the body and are constantly damaged, needing to be repaired quickly to prevent infection.
Minos, king of Crete, had made war upon Athens. He had come with a great fleet of ships and an army, and had burned the merchant vessels in the harbor, and had overrun all the country and the coast even to Megara, which lies to the west. He had laid waste the fields and gardens round about Athens, had pitched his camp close to the walls, and had sent word to the Athenian rulers that on the morrow he would march into their city with fire and sword and would slay all their young men and would pull down all their houses, even to the Temple of Athena, which stood on the great hill above the town. Then Aegeus, the king of Athens, with the twelve elders who were his helpers, went out to see King Minos and to treat with him.

Caterpillars are in a semi-hibernation phase
Explanation:
During winter caterpillars dehydrate themselves and generate a cryoprotectant that flows in their circulatory system (i.e., hemolymph) to avoid water freezing, thus preventing tissue damage. For example, Pyrrharctia Isabella (Lepidoptera, Erebidae), a caterpillar common in North America, can survive 1 week at −20°C. This condition is known as 'semi-hibernation' and it ends when the first temperate days arrive.

The FRAP technique occurs in a series of steps. Select every statement that correctly describes a step in the FRAP procedure.A. The speed of repair of the fluorescent marker is measured.B. All fluorescent molecules in the cell are irreversibly bleached.C. The relative mobility of the fluorescently labeled molecule is measured.D. The molecule of interest is fluorescently labeled.
Answer:
The answer is "Option C and Option D"
Explanation:
FRAP is used only for protein motion management. It travels throughout two dimensions in the plasma membrane. It includes many available-moving or immobile proteins. This technology uses globally marked fluorescent bleaching products, and also includes the fluorescent proteins, but one particular area is washed.
Its protein arc changes are detected by fluorescence reappearance. The fluorescence reappears at a certain stage if the protein can move freely. When the proteins aren't able to move quickly, fluorescent dyes are recovered after a little period, and fluorescence would not resurface during that point if the enzyme is immobile.

Which of these molecules would you least expect to easily dissolve in water?a. sucrose b. potassium chloride c. acetone d. 2-methylpropane e. acetic acid
Answer:
D. 2-methylpropane
Explanation:
The ability of a substance to dissolve in water is dependent on whether the molecules of the substance are polar or non-polar . Since water is a polar molecule, polar molecules readily dissolve in it in accordance with the principle of "like dissolves like".
Sucrose is a polar molecule since like water, it has bonds between electronegative oxygen, and electropositive hydrogen. Thus, it dissolves in water.
Potassium chloride is an ionic and hence polar molecule. It readily dissolves in water.
Acetone is a polar molecule due to the polar nature of the carbon-oxygen double bond in the molecules. Thus, it easily dissolves in water.
2-methylpropane is a non-polar molecule. The C-H bonds present in its molecules are non-polar, so it does not readily dissolve in water.
Acetic acid is a polar molecule due to carbon-hydrogen bond as well as oxygen-hydrogen bond. It readily dissolves in water and forms hydrogen bonds with water molecules.

Answer:
Explanation:
:
D. when the stomata are open, CO2 can get in but water can get out
Explanation:
Stomata are openings in leaf epidermis that are small they permit the entry of carbon dioxide and also allow the exit of water vapour.
Opening and closing of stomata is regulated according to physiological needs of the leaf.
Carbondioxide that is diffuses into the leave is used for photosynthesis.
Plant regulates water loss from the stomata. during the hot and cold weather water is conserves to maintain a cool environment in plant this is done by closing of stomata.

The correctly sequenced sections of the small intestine are: ____________, _____________, ____________.
Answer:
The correct answer is: duodenum, jejunum, ileum.
Explanation:
The small intestine is the part of the digestive tube that is mostly responsible for the absorption of nutrients that we incorporate through our diet, although part of the digestion also occurs in this segment (specifically in the duodenum).
The first segment, the duodenum, is the shortest of the three (about 25 centimeters in length) and is the one that is connected to the stomach. The duodenum receives the bile (from the liver), the pancreatic juice (from the pancreas), and the gastric chyme (from the stomach), to digest proteins and fat.
The second segment, called the jejunum, is about 2,5 meters long and its main task is to absorb the products of digestion, such as amino acids, carbohydrates, and fatty acids. This is how the nutrients reach our bloodstream and then the tissues where they are needed.
The last segment, the ileum, is the longest (about 3 meters long) and it's responsible for the absorption of vitamin B12 and bile acids. The ileum then connects to the large intestine, where water will be absorbed.
What happened in the 1980’s with environmental laws and regulations because some people claimed that the laws and regulations were hurting the economy?
Environment laws were stricter in the 1980s. Thus, people contested them saying that this will increase inflation.
What are environmental laws?Several environmental laws have been adopted over the last five decades in the United States. These laws have resulted in dramatic effects on the air and water quality of the nation. These have also reduced the exposure of people to toxic chemicals.
Various generations of the American public have benefitted from the legacy of leadership that has taken environmental issues as their primary priority. The benefits achieved by these laws and efforts have been controversial, to say the least.
Some of these laws have resulted in the utilization of huge amounts of public funds. Because of the misconception of a large number of the public that environmental issues are not serious or real, people believe that spending huge sums of money on environmental issues is a waste of a form of corruption.
Therefore, because the environmental laws were stricter in the 1980s, people contested them saying that this will increase inflation.

What was the result of the overhunting of sea otters along the Pacific Coast?
The sea otters on the Pacific Coast went extinct.
The sea urchin population expanded and consumed the kelp and damaged the habitat.
The sea urchin population was reduced to dangerous levels.
The kelp grew rapidly and created new habitat for fish.
Answer:
The sea urchin population expanded and consumed the kelp and damaged the habitat.
Explanation:
Sea otters prey on sea urchin and keep their population under control. Without sea otters, the sea urchin population cannot be kept in check and they will over consume kelp.
Devastating effects resulted from the excessive sea otter hunting around the Pacific Coast. Because sea otters are a keystone species in the ocean, they have an outsized impact on their surroundings. They eat kelp forests, which in turn eat sea urchins.
What happened without the sea otters ?Without sea otters to control their numbers, the sea urchin population grew and ate up the kelp, harming the environment. Fish depended on the kelp forests for cover, hence this led to a drop in the fish population. The sea otter species came dangerously close to extinction as a result of the rapid population fall.
The government has designated sea otters as a species of special concern in the United States, so this was very alarming.done action to safeguard them. The Pacific Coast environment was affected by the sea otter population collapse, which also had an impact on the fish population and kelp forests.
The overhunting of sea otters has led to the implementation of many conservation initiatives. Reintroducing sea otters to the Pacific Coast is one such initiative.
By lowering the sea urchin population and enabling the kelp to regenerate, this has helped to restore the ecosystem's equilibrium. In order to safeguard the species and assure its survival, the government has also imposed limitations on the hunting of sea otters.
