To send signals to control the body

Nerve cells: Transport signals around body

Tissue: Made of many cells

The main function of nervous tissue is C. To send signals to control the body. Nervous tissue is made up of specialized cells called neurons that are capable of transmitting electrical and chemical signals throughout the body. These signals allow the nervous system to control and coordinate various body functions, including movement, sensation, and thought processes. In addition to neurons, nervous tissue also contains support cells called glial cells that help to protect and nourish the neurons. Overall, nervous tissue plays a critical role in the functioning of the nervous system and the control of bodily functions.

Nonliving parts of an ecosystem are called abiotic components or abiotic factors. These include parts of the ecosystem that are non-living but still affect it. Examples include water, soil, air, temperature and sunlight.

The hormone produced by cells around the embryo that maintains the corpus luteum and pregnancy is called human chorionic gonadotropin (hCG).

Human chorionic gonadotropin (hCG) is a hormone that is produced by cells around the embryo, that is, trophoblastic cells that develop into the placenta, after fertilization. Its main function is to maintain the corpus luteum during the early stages of pregnancy. The corpus luteum is a temporary endocrine structure that develops after the release of an egg from the ovary, that is, after ovulation. It produces progesterone, which is essential for the maintenance of pregnancy in humans.

If an egg is fertilized by a sperm, the resulting embryo secretes hCG, which signals the corpus luteum to continue producing progesterone. This is necessary to prevent the lining of the uterus from shedding and to maintain the pregnancy. If the corpus luteum did not receive this signal, it would degenerate after about 12 days, and progesterone levels would decline. This would cause the lining of the uterus to be shed and menstruation to occur. The levels of hCG in a woman's blood and urine can be used to diagnose pregnancy. hCG levels rise rapidly in the first few weeks of pregnancy and can be detected by a blood or urine test. After about 10 weeks of pregnancy, hCG levels start to decline and eventually level off.

Answer:  the Mesozoic era came before the others however the accurate earliest eon is the Hadeon to be exact, but from the options you provided, answer it D.

Explanation:

Answer:

Explanation:

To determine whether the population is in Hardy-Weinberg equilibrium (HWE) for the Ab locus, we need to compare the observed genotype frequencies with the expected frequencies under HWE assumptions. The expected genotype frequencies under HWE can be calculated using the allele frequencies observed in the population.

Let's assume that the Ab locus has two alleles, A and B. We'll denote the allele frequencies as p and q, respectively, and the expected genotype frequencies under HWE as p^2 (AA), 2pq (AB), and q^2 (BB).

Given the genotyping data, we can analyze the observed genotype frequencies and calculate the expected frequencies. Let's say we obtained the following counts:

AA: 45 individuals

AB: 60 individuals

BB: 15 individuals

To determine the allele frequencies, we can calculate the allele counts. Let's denote the frequency of allele A as p and allele B as q.

Count(A) = 2 * AA + AB = 2 * 45 + 60 = 150

Count(B) = 2 * BB + AB = 2 * 15 + 60 = 90

Total count = Count(A) + Count(B) = 150 + 90 = 240

p = Count(A) / Total count = 150 / 240 = 0.625

q = Count(B) / Total count = 90 / 240 = 0.375

Now, we can calculate the expected genotype frequencies under HWE:

p^2 = (0.625)^2 = 0.390625

2pq = 2 * 0.625 * 0.375 = 0.46875

q^2 = (0.375)^2 = 0.140625

To determine whether the population is in HWE, we can perform a chi-square test using the observed and expected genotype frequencies.

Observed:

AA: 45 individuals

AB: 60 individuals

BB: 15 individuals

Expected (calculated above):

AA: (0.390625) * 120 = 46.875

AB: (0.46875) * 120 = 56.25

BB: (0.140625) * 120 = 16.875

To conduct the chi-square test, we compare the observed and expected frequencies for each genotype and calculate the chi-square statistic:

Chi-square = Σ [(Observed - Expected)^2 / Expected]

Calculating for each genotype:

AA: [(45 - 46.875)^2 / 46.875] = 0.07602

AB: [(60 - 56.25)^2 / 56.25] = 0.26765

BB: [(15 - 16.875)^2 / 16.875] = 0.10741

Summing the values:

Chi-square = 0.07602 + 0.26765 + 0.10741 = 0.45108

Degrees of freedom (df) = Number of genotypes - 1 = 3 - 1 = 2

To determine whether the population is in HWE, we compare the chi-square statistic with the critical value from the chi-square distribution table for the given significance level and degrees of freedom. If the calculated chi-square value exceeds the critical value, we reject the null hypothesis of HWE.

Alternatively, we can use statistical software or an online chi-square calculator to obtain the p-value associated with the calculated chi-square value. If the p-value is below the chosen significance level (e.g., 0.05), we reject the null hypothesis.

Further analysis:

If the population is not in HWE, it suggests that there are deviations from the expected genotype frequencies. The deviations could indicate factors such as non-random mating, genetic drift, selection, mutation, or migration.

To explore the deviations further and understand the factors contributing to the population's deviation from HWE, additional investigations can be conducted. These might include:

1.  Investigating mating patterns: Assessing whether individuals are preferentially mating with individuals of certain genotypes or from specific breeding units.

2.  Genetic drift: Analyzing the population size and potential bottlenecks or founder effects that could contribute to deviations from HWE.

3.  Selection: Examining whether natural selection is acting on the Ab locus, leading to deviations from expected genotype frequencies.

4.  Mutation and migration: Assessing the potential impact of new mutations or migration from other populations on the observed genotype frequencies.

By conducting these additional investigations, we can gain a better understanding of the factors influencing the population's deviation from HWE and further test the original hypothesis.

Gross productivity refers to the amount of carbon fixed.

Explanation:

Gross productivity refers to the amount of carbon fixed during the process of  photosynthesis by all producers such as plants and algae etc in the ecosystem. A large part of the energy that is produced in the process of photosynthesis is used by the plants in the metabolic processes of the producers such as respiration. The net productivity indicates that carbon dioxide plants that is used during the photosynthesis process substracted from carbon dioxide the plants releases during the process of respiration.

The curvature in the lower back (lumbar lordosis) helps balance the upper body on the pelvis. In the upper half of the pelvis, the size, shape, and orientation of the iliac paddles differ between apes and humans in a way that reflects our commitment to the walking biped.

In Ardipithecus ramidus it has been tapered and flattened on the sides to support the legs and they also have a shorter and wider pelvis. The three skeletal adaptations that result in a platypelloid pelvis include: an elongated ilium that repositions the gluteal muscles, a shorter distance between the sacroiliac and hip joints, and a ventrally titrated pelvis that aligns the sacroiliac and hip joints. and ultimately produces lumbar lordosis Human bipedalism is promoted by a narrow pelvis. However, in mammals, the pelvis is also the passageway through which newborn babies pass, and the birth canal must be large enough to accommodate a birth. Bipedalism resulted in skeletal changes in the joints of the legs, knees, and ankles, spinal vertebrae, toes, and arms. Most significantly, the pelvis became shorter and rounder, with a smaller birth canal, making childbirth more difficult for humans than other primates.

An external hordeolum, commonly known as a stye, is a localized infection of the eyelash follicle. It is typically caused by bacteria, most commonly Staphylococcus aureus.

Styes appear as a painful, red, and swollen bump on the eyelid, often with a visible pus-filled head. They can be uncomfortable and may cause temporary vision disturbances.

Styes usually resolve on their own within a week, but warm compresses and good hygiene practices can help alleviate symptoms and promote healing. It is important to avoid squeezing or popping the stye to prevent further infection.

In some cases, a doctor may need to drain the stye or prescribe antibiotics if the infection persists or becomes severe.
