ASAP What occurs after the homologous pairs are separated?
A. The sister chromatids separate.
B. Spindle fibers attach to the chromosomes.
C. Haploid cells are formed.
D. The nuclear envelope reforms.
Answer:
A
Explanation:
the sister chromatids separate
After the separation of homologous pairs, the sister chromatids are subsequently separated during meiosis II.
What is Homologous pair?Homologous pairs may be defined as those chromosomes which are very identical to one another and have the same size and shape.
In meiosis I, the separation of homologous pairs occurred. After this process, the sister chromatids are separated in meiosis II.
This separation leads to the production of a total of four products having the half number the chromosomes as compared to the original cell.
Therefore, the correct option for this question is A.

The celiac ganglion ________. Group of answer choices is located near the base of the superior mesenteric artery arises from the greater splanchnic nerve projects postganglionic fibers that innervate the small intestine and the kidney and urinary bladder arises from the lesser splanchnic nerve arises from the lumbar splanchnic nerve
Answer:
The correct answer is ''arises from the greater splanchnic nerve''
Explanation:
The greater splanchnic nerve or great adrenal nerve, originates in the thoracic sympathetic chain from vertebral levels T5 to T9 (T10). It runs over the bodies of the thoracic vertebrae and as it descends it becomes more anterior. It enters the abdomen crossing the diaphragmatic pillar and ends at the celiac plexus. The upper part of each celiac ganglion continues with the greater splanchnic nerve. The collateral or prevertebral ganglia innervate the abdominal and pelvic organs and viscera. The celiac ganglion receives preganglionic fibers from T5 to T12 and innervates the stomach, liver, pancreas, gallbladder, small intestine, spleen, and kidneys.

U can add more if u like it!Elodea is a plant that lives in water. Like all plants, elodea can make its own food through
process called photosynthesis. Oxygen gas is also produced during photosynthesis.
Photosynthesis can only happen in the presence of light. To measure the rate of
photosynthesis, a piece of elodea can be placed in an inverted test tube filled with a
sodium bicarbonate solution. Oxygen gas produced by photosynthesis will collect at the
top of the test tube.
A student has designed an experiment using elodea plants. The experimental setup is
shown in Figure 1-4
Which of the setups would serve as the control of the experiment?
Bucket
Lamp
Flashlight High
Natural
Elodea
Sodium
bicarbonate
solution
The controlled variable is kept constant during the whole experiment in all the different study groups. In this experiment, Sodium bicarbonate solution is the controlled variable.
------------------------
During an experiment, the controlled variables are kept constant in the control groups and the experimental groups. Unlike the independent variable, the controlled variables do not influence the results. These variables do not affect the response of the dependent variable.
In this experiment,
The independent variable → presence/absence of light reaching the plant. The researcher regulates the amount of light by using different elements such as the bucket, lamp, flashlight, and natural light. The dependent variable → oxygen production through which the researcher measures the photosynthesis rate. The controlled variable → Sodium bicarbonate solution. It provides carbon dioxyde, and must be constant in the four scenarios to avoid an effect on the results.-----------------------

Explanation:
For the numbered steps below, select the option that places them in the correct order. 1) The ribosome binds to the mRNA and uses tRNAs to translate mRNA into the corresponding amino acid polypeptide sequence. 2) The spliceosome removes introns. 3) The primary structure of the polypeptide chain undergoes hierarchical foldings to form the tertiary structure. 4) RNA polymerase binds to the promoter region of a gene and initiates transcription.
Answer:
first 4, then 2, then 1, and lastly 3
Explanation:
First, RNA polymerase binds to the promoter region of a gene on the DNA and initiates transcription. Transcription is the process by which we get mRNA (coding RNA) which is used as a template for protein synthesis. Then, in transcription, the resulting mRNA undergoes modification and maturation. This involves removal of introns, addition of 3'-poly-A tail and 5'-cap. Introns are sequences that do not code for protein and are hence removed. The structure that removes introns is the spliceosome. Thirdly, mature mRNA travels to the cytoplasm. Ribosome (composed of rRNA) binds to mRNA and tRNA to start the process of protein synthesis. The process of formation of protein is called translation. Lastly, the primary structure of protein may undergo folding to form a tertiary structure.

Frequently, a group of related species will each have a unique courtship ritual that must be performed correctly for both partners to be willing to mate. Such a ritual constitutes a ________ ________ reproductive barrier. Group of answer choices
Complete question:
Frequently, a group of related species will each have a unique courtship ritual that must be performed correctly for both partners to be willing to mate. Such a ritual constitutes a ________ ________ reproductive barrier.
Group of answer choices
A) behavioral . . . prezygotic
B) mechanical . . . postzygotic
C) temporal . . . prezygotic
D) gametic . . . postzygotic
Answer:
A) behavioral . . . prezygotic
Explanation:
The biological concept of species states that individuals of a species can not mate and reproduce with individuals of another species. But if they get to reproduce, the progeny will not be viable or fertile. There will not be any reproductive success.
There are different reproductive isolation mechanisms, which are barriers that inhibit or interrupt the genetic flow between different species.
Reproductive barriers are isolation mechanisms that prevent mating between two or more species. The prezygotic mechanism avoids fertilization between individuals of different species, while the postzygotic mechanism impedes the zygote to develop and reach the adult stage.
There are different types of reproductive barriers.
Pre-copulatory o pre-ziygotic:
Ecological or by habitat isolation; Seasonal or temporal; Sexual o ethologic; Mechanic; Gametes incompatibility.Postzygotic mechanisms or barriers include
Hybrid inviability, Hybrid sterility, Hybrid reduced viability or fertility, Cytoplasmic interactions.Behavioral isolation is also known as ethological isolation or sexual isolation. This is a prezygotic barrier that refers to the fact that even when many species occupy the same area, they are not sexually attracted to each other, and might be rejected because of behavioral factors, not getting to mate. This mechanism includes courtship patterns or mating rituals and specific chemical signals that allow recognition between individuals of the same species.
