Ball-and-socket joints allow this gymnast to complete many of the routines that she performs. A gymnast is shown. In which part of the body is a ball-and-socket joint found? wrist elbow hip knee
Answer:
c
Explanation:
There is a ball-and-socket joint in the hip area of the body. So, the correct option is C.
What is Ball-and-socket joint?The hip is home to the ball and socket joint. It is situated where the pelvic bone and femur (the thigh bone) meet. An example of a ball and socket joint is one in which one bone exactly resembles a ball and another bone precisely resembles a hollow or socket into which the first bone would fit.
This facilitates the bone's mobility in all planes. As a result, the hip has a ball and socket joint and can move in all directions. When compared to other joints, which are found in the fingers, knees, elbows, and toes, ball-and-socket joints, such as those in the shoulder and hip, permit only bending and straightening motions.
Therefore, the correct option is C.

If a cat with long black hair (Llbb) is crossed with a cat with short hair (llbb). What is the possibility that an offspring will have long black hair or short hair?
Answer:
50% long black hair and 50% short hair
Explanation:
Attatched is a screenshot of a punnett square that shows the possibilities of the offspring having long or short hair. In short, the genetics of long black hair only need one big "L", while the genetics of short hair need to have 2 short "l"s. So when we draw the punnett square and combine the genetics, we get 50% have Llbb, and 50% have llbb

The correct option is
D) variations in the completeness of epigenetic programming of the somatic cell nucleus
Explanation:
Nuclear transplantation method is the method in which the nucleus from a donor cell is removed and inserted in the target cell in which also it's nucleus has been removed or enucleated. The nuclear transplantations has slowed
embryologists to interfere the development of an organism and to study nucleus to direct development. It has been used for the cloning of several species.
Nuclear transplantation has failed in cloning because variations in the completeness of epigenetic programming of the somatic cell nucleus.
A farmer plants Bt cotton that is genetically modified to produce its own insecticide. Of the cotton bollworms feeding on these Bt plants, only 8% survive unless they have at least one copy of the dominant resistance allele R that confers resistance to the Bt insecticide. When the farmer first plants Bt cotton, the frequency of the R allele in the cotton bollworm population is 0.4. What will the frequency of the resistance allele be after one generation of cotton bollworms fed on Bt cotton
Answer:
0.6
Explanation:
According to hardy-weinberg principle,
P2+2pq+q2=1
P+q=1
q=1-p
Given that Allele R frequency is 0.4
and p represent the dominant allele
P=0.4
P2=0.4^2 = 0.16 for genotypic frequency
Since p+q=1
q=1-p
where q stands for recessive allele r frequency and q2 stands for genotypic frequency for allele r
q= 1-0.4= 0.6
q2=0.6 ^2
q2=0.36
Hardy-Weinberg principle states that are used to calculate the genetic variation of a population at equilibrium.
The frequency of the resistance allele in the cotton bollworm is 0.6.
Hardy-Weinberg equation can be given as:
P² + 2PQ + Q² = 1
where,
P = dominant allele (R)
Q = recessive allele (r)
Frequency of R allele = 0.4
From the equation:
P + Q = 1
or,
Q = P - 1
Genetic frequency of the R allele = P² = 0.4 x 0.4 = 0.16
Substituting the values:
Q = 1 - 0.4
Q = 0.6
Q² = 0.36
Thus, the frequency of the resistance allele will be 0.6.

The short-term controls of blood pressure, mediated by the nervous system and bloodborne chemicals, primarily operate via all but which of the following?
a. reflex arc associated with vasomotor fibers
b. reflex arcs involving baroreceptors
c. altering blood volume
d. centers in the medulla oblongata and the pons
Answer:
c. altering blood volume
Explanation:
The sympathetic nervous system acts to modulate blood pressure during short-term periods by modifying arterial pressure. The catecholamine hormone levels may be associated with an increase in the blood pressure by narrowing the blood vessels. Catecholamines are hormonal neurotransmitters released by the adrenal glands. These hormones derive from the metabolism of tyrosine amino acids and include, among others, adrenaline, noradrenaline and dopamine.

When glycogen phosphorylase is phosphorylated Group of answer choices its activity decreases. its activity increases. its activity is unaffected. none of these because that enzyme doesn't get phosphorylated.
Answer:
The correct answer is that its activity increases.
Explanation:
Glycogen phosphorylase comes under the category of phosphorylase enzymes. The mentioned enzyme catalyzes the rate-limiting step in the process of glycogenolysis within the animals. The sequential phosphorolysis of glycogen to discharge glucose-1-phosphate is catalyzed by the enzyme glycogen phosphorylase. Therefore, glycogen phosphorylase plays an essential part in the use of liver and muscle reserves of glycogen. After undergoing phosphorylation, the activity of the enzyme increases.

(1)Cells, like any factory, need energy to operate.
(2)Two different kinds of cellular power plants have evolved: some cells absorb energy directly from the sun, while others gather energy by eating other organisms that have stored it.
(3)Plants acquire energy directly from sunlight through the process of photosynthesis.
(4)In this process, molecules of chlorophyll or related pigments absorb photons from the sun.
(5)The photons’ energy is converted into chemical energy that the plant can use to grow and reproduce.
(6)In the course of this rather complicated chemical process, carbon dioxide and water from the cell’s surroundings are converted into glucose plus oxygen.
(7)The net effect of photosynthesis, then, is to remove carbon dioxide from the air, produce energy for the cell, and give off oxygen as a waste product.
(8)Animals, unlike plants, cannot convert the sun’s energy directly to food, and therefore must get theirs by eating plants or by eating animals that eat plants.
(9)The food you eat contains energy in the form of the bonds that hold its molecules together.
(10)After the food has been broken down, it is taken into the cells, where its energy is released by a process called respiration.
(11)This process allows molecules like glucose to combine with oxygen, thereby releasing the energy tied up in the molecular bonds.
(12)Its waste product is carbon dioxide, which you breathe out.

Why?
NEED ANSWER ASAP SOMEBODY HELP
The information stored in the order of bases is organized into genes: each gene contains information for making a functional product. The genetic information is first copied to another nucleic acid polymer, RNA (ribonucleic acid), preserving the order of the nucleotide bases. Genes that contain instructions for making proteins are converted to messenger RNA (mRNA). Some specialized genes contain instructions for making functional RNA molecules that don’t make proteins. These RNA molecules function by affecting cellular processes directly; for example some of these RNA molecules regulate the expression of mRNA. Other genes produce RNA molecules that are required for protein synthesis, transfer RNA (tRNA), and ribosomal RNA (rRNA).
