Answer:
Explanation:
The number of copies of an allele in a population divided by the total number of all alleles for that gene in a population is the allele frequency. For a gene with two alleles whose frequencies are p and q, the Hardy-Weinberg equation states that the genotypes that are possible for the population are p^2 + 2pq + q^2, which is equal to
Name the reproductive parts of an angiosperm. Where are they located? Explain in brief the structure
of its female reproductive parts with labeled diagrams.
Answer:
Stamen is the male reproductive part and the pistil is the female reproductive organ.
Explanation:
Stamen or androecium is the male reproductive part and the pistil or carpel or gynoecium, is the female reproductive organ of an angiosperm. Both are located in the flower of a plant. In flower, male reproductive part is present in the form of pollen located at certain height and the female part is located lower side so that the pollen falls on the stigma and reaches to the ovary where female cells or ovules is present that fused with pollen produces seed.

The common grackle is a species of robin-sized blackbirds that are fairly common over most of the
United States. Suppose that long tails (L) were dominant to short tails (1) in these birds. A female short-
tailed grackle mates with a male long-tailed grackle that had one parent with a long tail and one parent
with a short tail. What is the tail length probability of their offspring?
Answer:
Long tail (Ll) = 1/2 or 50%
Short tail (ll) = 1/2 or 50%
Explanation:
This question involves a single gene coding for tail length in grackle birds. The allele for long tails (L) were dominant to short tails (l) in these birds. This means that a bird that is heterozygous (Ll) for the gene will be phenotypically long tailed.
According to the question, a female short-tailed grackle (ll) mates with a male long-tailed grackle that had one parent with a long tail and one parent with a short tail. This male grackle will have a genotype: Ll because of his parental genotype. Hence, crossing ll × Ll, the following gametes will be produced by each parent:
Ll (male) = L and l
ll (female) = l and l
Using these gametes in a punnet square (see attached image), the following proportion of offsprings will be produced:
Ll, Ll, ll and ll
2 Ll out of 4 are long-tailed i.e 1/2 or 50% probability
2 ll out of 4 are short-tailed i.e 1/2 or 50% probability

what do you see inside the cell? three chromosomes three sister chromatids three homologous pairs of chromosomes three homologous pairs of chromatids
Answer:
three homologous pairs of chromosomes
Explanation:
Inside the cell we can see three homologous pairs of chromosomes as in humans there are 23 pair of homologous chromosomes and they are very similar in size and shape.
Three chromosomes are not possible to see because there are only two chromosomes and if anyone is having three chromosomes then the person is suffering from down syndrome having 47 chromosomes.
Three sister chromatids is also not possible because only two sister chromatids are found after DNA replication.
Three homologous pairs of chromatids is also not possible because chromatids are not found in pair and sister chromatids are called homologous chromosomes.
Hence, the correct answer is "three homologous pairs of chromosomes".

Fossil evidence can be used to determine the degree to which different organisms are related. The relatedness of organisms can also be determined by examining
A. internal and external anatomical features of the organisms.
B. ancestors that the organisms share in common.
C. chemical processes that occur within the organisms.
D. all of these
Answer:
D
Explanation:
The relatedness of organisms can also be determined by examining internal and external anatomical features of the organisms, ancestors that the organisms share in common and chemical processes that occur within the organisms. Therefore, option (D) is correct.
What are anatomy characteristics?Human anatomy is characterized by reproduction, inheritance, cellular organization, growth and development, response to stimuli, evolutionary-adapted traits, and metabolism.
Anatomical characteristics that are shared by multiple organisms as a result of a common ancestor are known as homologous structures. Homologous structures, or homologies, are the tetrapod limbs.
the comparative study of the body structures of various animal species to comprehend the adaptive changes they have undergone since common ancestors evolved.

what evidence and logical reasoning support the conclusion that anaerobic organisms evolved first, followed much later by aerobic organisms?
Answer: The atmosphere of the early Earth consists mainly of carbon dioxide and nitrogen, with little or no oxygen. In this case, the ancient prokaryotes are anaerobic, which evolved in the absence of oxygen. Eventually, when photosynthetic bacteria became common, they released oxygen and changed the Earth's atmosphere.

Select one:

b. cooler than usual waters in the tropical Pacific
c. warm waters traveling eastward toward South America
d. cool waters causing colder than normal temperatures in the Southeast Incorrect
Answer:
D
Explanation:
I think so
1. Coriolis effect would deflect the path of the air mass to the west.
2. A horizon would provide the best assessment of the fertility of a soil.
3. Label E is located above Label D.
4. A La Niña can be described as cooler than usual waters in the tropical Pacific
The correct options for 1, 2, 3 and 4 are B, B, D and B respectively.
The Coriolis effect is the deflection of moving air (or an object) due to the Earth's rotation. The air moving in the northern hemisphere is deflected to the right of its intended path due to the Coriolis effect. As a result, in the Northern Hemisphere, air masses traveling from high to low latitudes will be deflected west.
The A horizon, commonly known as the topsoil, contains the most organic matter and nutrients, making it the most fertile layer of soil. This is the layer in which organic components such as degraded plant matter and humus interact with mineral particles to provide an optimal environment for plant growth.
The location at latitude D, which lies above the equator and parallel to the top of the Hadley cell, is where you might expect to find the driest average conditions in the Hadley cell circulation pattern mentioned in the question (north of the equator). Due to the compression, the air in the Hadley cell becomes warm and dry as it descends, resulting in arid or desert-like conditions.
La Niña is a climate phenomenon that causes cooling of sea surface temperatures in the central and eastern tropical Pacific Ocean. It represents the inversion phase of the El Niño–Southern Oscillation (ENSO) cycle.
Therefore, the correct options for 1, 2, 3 and 4 are B, B, D and B respectively.
