Genotypes of offspring:
Phenotypes of offspring:
Plz help me
Answer:
Crossing two chickens heterozygous for the trait feather color, when brown feathers are dominant over red feathers, will produce offspring with brown and red feathers in a brown:red phenotypic ratio of 3:1.
Explanation:
Knowing that in chickens brown feathers are the expression of the dominant allele (B) and the recessive allele is red (b), crossing two heterozygous individuals (Bb) will result in offspring that are likely to have brown or red feathers.
The cross can be represented by a Punnett Square:
Bb X Bb cross
alleles B b
B BB Bb
b Bb bb
Where the result is:
Genotypes:
Bb, 50% BB, 25% bb, 25%Phenotypes:
Brown feathers, 75% Red feathers, 25%.In this case, the probability of having brown or red feathers is 3:1.

A. Rudolf Virchow
B. Charles Darwin
C. Anton van Leeuwenhoek
D. Robert Hooke
E. All of the above helped in developing the cell theory
PLEASE HELP!!
The given statement is false and the cell hypothesis was created by Rudolf Virchow, Theodore Schwann, and Matthias Jakob Schleiden, hence option B is correct.
What is cell theory?As a result, van Leeuwenhoek and Schwann did not independently develop the cell hypothesis.
The scientific idea that cells make up living beings, that they are the fundamental structural and organizational unit of all species, and that they all originate from previously existing cells is known as cell theory.
Typically, three scientists Theodor Schwann, Matthias Jakob Schleiden, and Rudolf Virchow are credited with creating the cell theory.
Therefore, Schwann and Schleiden proposed that cells were the fundamental building block of life in 1839.

How do typical human body temperature and pH explain why lactase can work efficiently in the human body of most humans?
Answer:
Lactase requires 6 pH and 37 degree Celsius temperature.
Explanation:
Lactase can work efficiently in the human body of most humans because the pH and temperature of the body is favorable for the lactase to work. Lactase has a range of pH from 2 to 7 but work best at the pH 6 and at the temperature of 37 degree Celsius which is the human body temperature and pH so that's why the lactase can work efficiently and effectively in the human body.
How does a lack of water in an environment affect the amount of carbon dioxide a plant absorbs?
Answer:
the lack of water in an environment affect the amount of carbon dioxide a plant absorbs by rising carbon dioxide concentrations will increase plant growth. More rapid leaf area development and more total leaf area could translate into more transpiration. Rising carbon dioxide concentrations will decrease leaf stomatal conductance to water vapor. This effect could reduce transpiration.

The lack of water in an environment affect the amount of carbon dioxide a plant absorbs by rising carbon dioxide concentrations will increase plant growth.
What is carbon dioxide?More rapid leaf area development and more total leaf area could translate into more transpiration.
Rising carbon dioxide concentrations will decrease leaf stomatal conductance to water vapor. This effect could reduce transpiration.
Carbon dioxide (CO2) is a colorless gas with a sour taste and a slight harsh odor. It is one of the most significant greenhouse gases associated with global warming, but it only makes up a small portion of the atmosphere on Earth (roughly 3 volumes per 10,000).
Therefore, The lack of water in an environment affect the amount of carbon dioxide a plant absorbs by rising carbon dioxide concentrations will increase plant growth.

1. Fallopian tube
2. Uterus cavity
3. Bladder
4. Urethra
5. Ovary
6. Ovary
7. Uterus
8. Vagina
Explanation:
The vagina is a muscular tube-shaped connection that extends from the vaginal opening to the uterus. Vagina walls are very muscular, which allows contraction and expansion movements. It is located just between the urethra/bladder and the rectus. Menstruation, copulation, and birth occur through the vagina.
The uterus is a muscular and hollow organ, also located between the bladder and the rectus. The uterus wall is formed of three layers: perimetrium, mesometrium, and endometrium. This organ is separated into two parts: the uterus body and the cervix, which protrudes to the superior area of the vagina. Here is located the uterine opening that communicates the vagina with the uterus cavity. The final rounded portion is called "uterus fundus", and each of the two extremes is called "uterus horn". These horns are united to the Fallopian tubes.
Fallopian tubes are ducts that communicate each of the ovaries with each of the uterus horns. These tubes receive the oocytes that are getting out of the ovaries and carry them to the uterus. In their way, they might meet a spermatozoid and be fertilized.
Both ovaries have an oval shape, of approximately 3 cm in length each and 1 cm in width. They are located at each side of the uterus and are in charge of the production of the feminine gametes (the whole ovulation process).

the diagram shows a model of how a hydra reproduces by budding
Answer:
B. It shows offspring that have the same genes as the parent.
C. It shows asexual reproduction.
Explanation:
Hydra reproduces by budding which is kind of asexual reproduction. In budding, a small bud appears on the body of that organism and grow in size with the passage of time and finally detached from the parent body. so no fusion of gametes occurs so no chance of genetic variation. The offspring have the same genes as the parent because it forms from one parent.

how are checkpoints currently behaving in sally cancer cells
Answer:
Instable behavior.
Explanation:
The checkpoints currently behaving instable in sally cancer cells because mutants show genetic instability so this instability is the cause of cancer disease. Two checkpoints are sensitive to DNA damage, one occur before mitosis cell division and the other occur before replication of DNA. So damage occur in these two check points leads to instable behavior of cancer cells.

Which of the following is true regarding the large intestine?
А
It is the major site of water absorption.
B
It is four times as long as the small intestine.
Most chemical digestion occurs there.
D
It contains salivary glands, which secrete amylase.
The statement that is true regarding LARGE INTESTINE is option A which states that It is the major site of water absorption.
The LARGE INTESTINE is part of the alimentary canal in the digestive system of mammals. The main function of
• Is to absorb water and salts from the material that has not been digested as food, and
• get rid of any waste products left over.
The main parts of the LARGE INTESTINE includes:
• the cecum,
• the colon, and
• the rectum
From the cecum, the undigested food passes into the colon. Here, WATER is ABSORBED. This concentrates the waste products and makes them semi-solid. In this state, the waste products are called faeces. Faeces pass into the rectum and out of the body through the anus.
Therefore the statement that is true regarding LARGE INTESTINE is that It is the major site of water absorption.

Suppose that this population of mice has stabilized so that both white and brown appear. White mice survive better in the winter and brown mice survive better in the warmer months. If a group of these mice migrated to an area that didn't get snowy in the winter, what do you think would be the long term effect on the color of these mice? Explain why.
Answer:
more brown mice would survive as the white ones without the snow to camouflage them from predators would get picked off by predators more than the brown ones
Explanation:
Over a long period of time, the population of white mice will reduce or would disappeared.
What is Natural Selection?It is a method of evolution in which the organisms of a population are selected by specific parameters.For example - color, running speed, etc.In a place where the winter is not snowy, the white mice will be easily caught by predators. Brown mice have less chance to be caught by predators, hence surviving better in non-snowy places.Therefore, over a long period of time, the population of white mice will reduce or would disappeared.
