Which step occurs in meiosis to prepare for fertilization in sexually
reproducing organisms?

Answers

Answer: 12 sexual reproduction and meiosis concept outline

Explanation: The process of meiosis produces unique reproductive cells called gametes, which have half the number of chromosomes as the parent cell. Fertilization, the fusion of haploid gametes from two individuals, restores the diploid condition. Thus, sexually-reproducing organisms alternate between haploid and diploid stages.

In what order do species appear during primary and
secondary succession?

Answers

Answer:

here you go :)

Explanation:

Primary succession is one of two types of biological and ecological succession of plant life, occurring in an environment in which new substrate devoid of vegetation and other organisms usually lacking soil, such as a lava flow or area left from retreated glacier, is deposited. In other words, it is the gradual growth of an ecosystem over a longer period of time.

In the primary succession, species like algae, fungi, and lichens are preset. In the secondary succession, the pioneer species present, that already existed in the environment.

What are primary and secondary succession?

One of two types of biological and ecological succession of plant life. They are primary succession that takes place in environments where fresh substrate is deposited that is devoid of plants and other species that typically lack soil, such as lava flows or areas left behind from glaciers that have receded.  

In other words, it is the steady development of an ecosystem through time.

Thus, Algae, fungus, and lichen species are established during the primary succession. The pioneer species that were previously existing in the habitat are found in the secondary succession.

What are the physical structures and organs of birds?

Birds are the warm-blooded animals. Their forelimbs are generally modified into wings. They have a well-developed flight muscles which help during the flight of bird. Their hind limbs are adapted for the purpose of walking, hopping, perching, grasping, wading and swimming.

The ovaries produce the eggs. The ovaries are responsible for producing eggs in birds. Therefore, if there is an error in the table that incorrectly identifies the function of the ovaries, it is important to correct it by stating that the ovaries produce the eggs.

Purple: FF /White: ff the principles of dominance and segregation to analyze the diagram, alleles would you expect in the F1 plants. Thus, option (a) is correct.

What is segregation?

The Segregation Principle defines how pairs of gene variations are divided into reproductive cells. Gregor Mendel discovered the segregation of gene variants, known as alleles, and their accompanying qualities in 1865. During meiosis, allele pairs (different features of the same gene) are separated so that they can pass to distinct gametes.

The diagram was analyzed using the principles of supremacy and segregation. The principle of the impact in segregation was described as Purple: FF / White: ff. This inheritance pattern is known as partial dominance, which means that neither allele is completely dominant over the other: both genotypes can be seen at the same time.

As a result, the Purple: FF /White: ff the principles of dominance and segregation.

Genotype, and Phenotype

In a flock of birds, parents can raise small clutches on their own but can increase their clutch size if they have a helper. You want to see if altruistic behavior is likely to spread. To do this you observed a male bird that stayed at his birth nest for a year to help raise the offspring of his father and his stepmother (the original mother died) and then built his own nest the following year. You calculated direct fitness (cost) for the male bird by counting the number of offspring he produced in one year and multiplied it by ½ due to the relatedness between parents and offspring. To calculate his indirect fitness (benefit), you took the total number of offspring produced in his birth nest by his father and stepmother when he assisted them and multiplied it by ½. To determine if this altruistic behavior would spread you subtracted the cost from the benefit to determine whether it was greater than 1. What did you do wrong

Answers

Answer:

The mistakes made

Altruistic behavior is measured as ; b - c > 0  and not b - c > 1 relatedness for half siblings = 0.25 and not 1/2

Explanation:

The relatedness between ; Mother, father, daughter and son = 0.5 ( 1/2 )  which is included in the direct fitness category  ( For the MALE bird )

The relatedness for the Half brother and Half sister of the male bird = 0.25 ( 1/4 ) ( indirect fitness )

hence applying  Hamilton's rule

Relatedness = rb - c > 0

where b = benefit , c = cost

∴Total fitness = ∑ direct fitness + ∑ indirect fitness

                       = 0.5x + 0.25y

hence the mistakes made

Altruistic behavior is measured as ; b - c > 0  and not b - c > 1 relatedness for half siblings = 0.25 and not 1/2

A scientist injects a drug called rifampicin, which inhibits RNA synthesis, into a bacterium. What is the most likely direct result of this alteration?

The bacterial DNA will stop replicating.
The bacterial DNA will replicate in an uncontrolled way.
The process of protein synthesis will stop in the bacterium.

Answers

The most likely direct result of this alteration is that the bacterial DNA will stop replicating. Thus, the correct option for this question is A.

What is Rifampicin drug used for?

The drug Rifampin is used to treat tuberculosis (TB) in many different parts of the body. It is also used by patients who have meningitis bacteria in their nose or throat who do not show symptoms of the infection to prevent the spread of the bacteria to other patients.

Rifampin specifically inhibits bacterial RNA polymerase. It is an enzyme that is responsible for DNA transcription, by forming a stable drug-enzyme complex with a binding constant of 10(-9) M at 37 C. The corresponding mammalian enzymes are not affected by rifampin.

Therefore, the most likely direct result of this alteration is that the bacterial DNA will stop replicating. Thus, the correct option for this question is A.

Mitosis consists of four basic phases: Prophase, Metaphase, Anaphase, and Telophase. These phases occur in strict sequential order, and cytokinesis - the process of dividing the cell contents to make two new cells - starts in anaphase or telophase. Stages of mitosis: prophase, metaphase, anaphase, telophase.

A. Prophase

Prophase is the first phase of mitosis, the process that separates the duplicated genetic material carried in the nucleus of a parent cell into two identical daughter cells.

B. Metaphase

Metaphase is the third phase of mitosis, the process that separates duplicated genetic material carried in the nucleus of a parent cell into two identical daughter cells.

C. Anaphase

Anaphase is the fourth phase of mitosis, the process that separates the duplicated genetic material carried in the nucleus of a parent cell into two identical daughter cells.

D. Telophase

Telophase is the fifth and final phase of mitosis, the process that separates the duplicated genetic material carried in the nucleus of a parent cell into two identical daughter cells.

The third stage of mitosis, known as metaphase, is when the genetic material that was replicated and carried in the parent cell's nucleus is split into two identical daughter cells.

What are the different phases of mitosis?

There are four fundamental stages of mitosis: prophase, metaphase, anaphase, and telophase.

Cytokinesis, which is the process of separating a cell's contents into two new cells, begins in either anaphase or telophase, where the phases are strictly sequentially ordered.

The division of the duplicated genetic material contained in a parent cell's nucleus into two identical daughter cells is called mitosis, and the process begins with the prophase.
