Answer:
What are specialized cells
Bb and bb the genotypes of the parents and offspring of a cross between a black male and a brown female produce 1/2 black offspring and 1/2 brown offspring.
What is the dominant allele?The connection between two genetic variants is referred to as dominant. Each gene has two alleles that an individual inherits from each parent. One allele of a gene, known as the dominant gene, will be expressed if the alleles are different. The impact of the other allele, known as the recessive one, is concealed.
The Cross between parents is Bb x bb
Gametes- B and b
Offsprings- Bb, Bb, bb, bb
The crossing analysis is attached in the image below.
A person needs two copies of a recessive allele, one from each parent, in order for it to result in a recessive phenotype.
Therefore, Bb and bb the genotypes of the parents and offspring of a cross between a black male and a brown female produce 1/2 black offspring and 1/2 brown offspring.

Answers
Answer:
1. Glycolysis
2.false (not sure)
3. Cellular respiration is the process through which cells convert sugars into energy.
4 C6H12O6 + 6O2 → 6CO2 + 6H20 + energy (Glucose + Oxygen yields Carbon Dioxide + Water + Energy)
5. Fermentation is a chemical process by which carbohydrates, such as starch and glucose, are broken down anaerobically.
6 anaerobic
7 alcoholic and lactic acid.
8 Alcoholic fermentation is a biotechnological process accomplished by yeast, some kinds of bacteria, or a few other microorganisms to convert sugars into ethyl alcohol and carbon dioxide. ... Alcoholic fermentation begins with the breakdown of sugars by yeasts to form pyruvate molecules, which is also known as glycolysis.
9 In this reaction, a phosphate group (in red) is transferred from phosphocreatine to ADP to form ATP very rapidly, allowing muscle contraction to continue for about 10 seconds. When phosphocreatine is depleted, the muscles must turn to metabolism of fuel molecules to produce more ATP to power physical activity.
10 At this point, the runners' muscle cells are producing most of their ATP by lactic acid fermentation, which can usually supply enough ATP to last about 90 seconds.
12 After that, the body begins to break down other stored molecules, including fats, for energy. If photosynthesis is the process that "deposits" energy in a "savings account," then what is cellular respiration? It is the process that "withdraws" energy.
13 Cellular Respiration and Photosynthesis are almost opposite processes because photosynthesis removes carbon dioxide from the atmosphere while cellular respiration puts back carbon dioxide. Cellular respiration uses oxygen and has it's waste product of carbon dioxide (CO2).

O They are yellow stars.
O Many are supergiants
O Several are white dwarfs.
O Each is part of the main sequence.
Answers
Answer:
Many are supergiants.
Explanation:
A star's size and core temperature determine its brightness. The brightest stars tend to be blue or blue white. Supergiants and red giants are in the region above the main sequence of stars, so that isn't true. Red are the dimmest. Yellow stars are in the middle of that spectrum. White Dwarfs are dimmer than the Sun, red giants and blue supergiants.

. What is the width of Grandmother’s pelvis, measuring from the pelvic brim? How does her pelvis differ
from Grandfather’s?
Answers
The width of Grandmother’s pelvis, measuring from the pelvic brim is 2cm.
The grandmother has a wider pelvis than the grandfather.
The pelvic brim is found at the edge of the pelvic inlet and measures around
2cm. The pelvis in females are always wider than those found in males. This
is due to the adaptation of the female pelvis to child birth.
The pelvis being wider aids the passage of the foetus from the womb and
eases childbirth. This is the reason why the grandmother has a wider pelvis
than the grandfather.

Imagine that you are managing a large wildlife preserve that was formerly a cattle ranch. You know from historical accounts that wild sheep used to live there, but they were hunted until the local population was exterminated. After doing some research to determine what might be an appropriate starting population, you introduce them. Food is abundant and they have no natural predators. You then spend several years graphing the number of individuals (on the vertical axis) against the number of generations (on the horizontal axis). By the 10th generation, the population begins to reach carrying capacity.

What BEST defines this mathematical model used in population studies?
Answers
The mathematical model used in this population study is known as the logistic growth model.
What is logistic growth model?The logistic growth model is a mathematical model that is used to describe the growth of a population over time. It is based on the idea that the growth of a population is limited by resources such as food, habitat, and space, and that as the population grows, the rate of growth begins to slow. This results in a curve that starts out steep and then levels off as the population approaches its carrying capacity, which is the maximum population size that can be sustained in a particular environment.
In the scenario described, the population of wild sheep is introduced to a wildlife preserve where food is abundant and there are no natural predators. This means that the population is able to grow at a relatively fast rate, but as the population increases, it begins to approach the carrying capacity of the preserve. At this point, the rate of growth begins to slow, and the population levels off.
This is reflected in the graph, which shows the population increasing rapidly at first and then leveling off as it reaches carrying capacity. The logistic growth model is often used to understand and predict the growth of populations in a variety of contexts, including agriculture, biology, and economics.

Answers
Answer:
nucleus...controls all the activities of the cell and carrries the genes
mitochondria..site for respiration that yields energy for the cell
endoplasmic reticulum... protein synthesis and lipids metabolism
vacuoles.... handle waste products and are responsible for regulation of osmotic pressure of a cell also
Explanation:
is this helpful?
Mitochondria are membrane-bound cell organelles (mitochondrion, singular) that generate most of the chemical energy needed to power the cell's biochemical reactions.
A vacuole is a membrane-bound cell organelle. In animal cells, vacuoles are generally small and help sequester waste products.
The endoplasmic reticulum can either be smooth or rough, and in general its function is to produce proteins for the rest of the cell to function.

b. She needs to know the phenotype of the first plant.
c. She needs to know the genotypes of the previous plant generation.
d. She needs to know the genotype of the second plant.
Answers
D. She needs to know the genotype of the second plant.
What is a punnett square?A Punnett square is a tool used to predict the outcome of a genetic cross between two individuals. To use a Punnett square, you need to know the genotypes of both of the individuals involved in the cross. In this case, the student knows the genotype of one parent plant, but does not know the genotype of the second plant.
Therefore, she cannot use a Punnett square to predict the outcome of the breeding experiment. In order to do so, she would need to know the genotype of the second plant.

No Water Required
Seeds do not necessarily need water to germinate and grow, although some require water to soften the seed coat. Large seeds in dry conditions will hold water and allow the growing plant to grow deep roots without the need for rain or additional water.
Fully Developed Embryo
Inside each seed is a fully developed embryo that is ready to begin growing. Many seeds go through a dormancy period, which is a period when the seed will not germinate and begin growing. When conditions are right, the embryo germinates and begins growing. Having an embryo already grown gives a seed plant a better chance at survival as opposed to a spore.
Nourishment
Each seed contains nourishment for the embryo inside the seed. The endosperm is the tissue that surrounds the embryo inside the seed. The embryo uses nourishment provided by the endosperm as a jump start to begin growing.
The Seed Coat
The seed coat is one major advantage seeds have over spores. A spore is a single-celled organism that develops into a plant or fungus when the conditions are right. The spore has no outer protection.

Incubation is 18 days from the time cockatiels sit in earnest, therefore, count a few extra days if sitting is delayed. Allow the female to abandon the eggs of her own accord rather than removing them even if incubation time is over, because your cockatiel will only lay additional eggs if she reacts to their absence.
