Which phase of mitosis is shown at the
letter 'A'?
A Interphase
B Prophase
C Metaphase
D Anaphase
E Telophase
A newly created cell and its nucleus go through a series of modifications known as prophase and interphase in order to prepare for cell division. It is also known as the preparatory phase.
Exists the M phase?When a cell is in the M phase, it divides, first through nuclear division (mitosis), then through cytoplasmic division (cytokinesis). The DNA is replicated in the earlier S phase, and cohesins keep each replicated chromosome's two copies (known as sister chromatids) bound to one another.
Is the M phase the longest phase?Prophase is the first and longest phase of mitosis. Chromatin gathers into chromosomes and the nuclear envelope, which is the membrane that encloses the nucleus, disintegrates during prophase. DNA synthesis or replication takes place during the S phase of a cell cycle, which happens during interphase and comes before mitosis or meiosis. Before a cell starts mitosis or meiosis.

Select the most accurate of the following statements: Group of answer choices The vascular bundles of gymnosperms contain xylem only, whereas those of angiosperms contain both xylem and phloem Angiosperms produce specialized shoots bearing modified leaves to attract pollinators and protect gametes All gymnosperms have narrow, needle-like leaves whereas all angiosperms have broad, net-veined leaves Gymnosperm embryos are exposed to the elements, whereas the embryos of angiosperms are packaged with a food source inside a seed coat Gymnosperms have substantially more species than angiosperms
Answer:
The correct answer is - all gymnosperms have narrow, needle-like leaves whereas all the angiosperms have broad, net veined leaves".
Explanation:
Gymnosperm and angiosperm both possess xylem and phloem in their vascular bundles or vascular tissues for the transport of water and nutrients or minerals respectively.
Angiosperm or the flowering plants are the largest groups of all plant groups and more diverse than other even gymnosperms are less diverse and fewer in number in comparison to angiosperm.
All gymnosperms consist of narrow, needle-like leaves and in angiosperms, leaves are broad, net veined.
Both gymnosperms, as well as angiosperms, have xylem and phloem throughout their vascular tissues just to carry moisture and nutrients as well as rare earth minerals.
Angiosperms, or blooming plants, seem to be the most diverse as well as numerous vegetation groupings. Gymnosperms, on the other hand, have become less diverse but also numerous in contrast to angiosperms.Thus the above statement is correct.

Which air mass is likely to form over Minneapolis and what weather conditions would it bring?
Question 5 options:
mT bringing warm moist conditions
cT bringing warm dry conditions
mP bringing cold and moist conditions
cP bringing cold and dry conditions
Answer: The answer is cT bringing warm dry conditions
Explanation: Because, What type of weather does an air mass usually bring?
They can bring anything from tropical warm and humid days to arctic cold depending on the type of air mass. Fronts form the boundaries of air masses with differing properties. The most severe weather usually occurs when dry-cold continental polar air clashes with warm-humid maritime tropical air.
A scientist is attempting to build a cladogram that shows the evolutionary closeness of three organisms in relation to humans.
After doing DNA analysis, they determine that the organisms share the following percentages of DNA:
Organism A and humans share 85% of their DNA.
Organism B and humans share 80% of their DNA.
Organism C and humans share 90% of their DNA,
Based on this information, which order should they go on the cladogram (from least related to most related)?
(1 point)
O A, B, C, humans
OB, A, C, humans
o C, B, A, humans
OC, A, B, humans
B, A, C, Humans is the correct answer
Heyo! ;D
So, just to give you a heads up, these do change and sometimes vary for some, however please make sure before you look into these. Thanks! Just pre-warning!
1. The two organisms that are the most closely related would be:
~A and C~2. Based on the information of percentages of DNA, the order they should go on the cladogram (from least related to most related) would be:
~B, A, C, humans~3. The evidence that would support the relationships shown on the graph between amphibians, reptiles, birds, and mammals would be:
~Mammals have more genes in common with birds than with amphibians.~4. The piece of evidence, if true, that would most likely weaken the hypothesis that humans and chimpanzees have a common ancestor to gorillas would be:
~The cells of the eye on embryos of gorillas and humans follow a similar pattern of development while chimpanzee embryos are different.~5. The similarity of the structures of the forelimbs of bats and humans are known as:
~homologies~because they result from species evolving:
~from the same common ancestor~6. The suggestion above discussing the fact "all vertebrate embryos have a tail and gill slits at some point during embryonic development" helps to suggest that:
~These species share a common ancestor.~7. The conclusion that can be made based on the statement "Fossil A is found closer to the surface compared to Fossil B." would be:
~Fossil B is most likely older than Fossil A.~8. The statement that could be used to explain the similarity of the developmental process of vertebrate embryos would be:
~All vertebrates develop a backbone that protects the spinal cord.~9. The term for the remains, imprints, or traces of living things from a previous geological age would be:
~Fossils~10. The reason some mutations, or changes in the sequence of DNA, don't have any effect on the characteristics of the organisms would be:
~The mutated sequence still codes for the same amino acid.~11. What is typically studies when analyzing not-yet-born (or unhatched) animals is:
~embryological development.12. What scientists can analyze to get a better understanding of how plants and animals evolved from a common ancestor is:
~DNA molecules~13-16. The rest of the questions are written responses, 13-15 being short answers and the last being a single 3-5 sentence response. But no fear!

Gene (C) controls fur pigmentation in Himalayan rabbits. Although the two rabbits in the picture have the same genotype, the rabbit reared at
temperatures above 30°C has no black fur pigmentation on its ears, nose, and feet.
Answer:
The gene C is inactive at these higher temperatures. The gene fails to express the particular phenotype specified by the gene. In this case, temperature is an environmental influence that affects gene expression.

The crayfish, like some other animals, can regenerate lost appendages. It can
also undergo autotomy. Investigate autotomy in crayfish. What is it? How is it
related to regeneration?
Crayfish exoskeleton is the part of the creature which shows autotomy and regeneration.
What is autotomy?Autotomy or self-amputation is the behavior of an animal shedding or discarding one or more of its own appendages, frequently as a self-defense technique to elude a predator's grasp or to distract the predator and thus allow escape.
Are Autotomy and regeneration the same mechanisms?No. Autotomy and regeneration are different processes however they are similar:
Certain living organisms like crayfish exhibit two processes: autotomy and regeneration.The primary distinction between autotomy and regeneration is that during autotomy, body parts are eliminated or shed from the body, but during regeneration, body parts are replaced or formed into a new creature or the amputated body part is regrownHow does crayfish undergo autotomy and regeneration?Crayfish belong to the class of crustacenas which regularly shed their exoskeleton through autotomy and regrow a new one through regeneration.the exoskeleton is rigid and hence does not grow along the size of the creature which allows the creature to shed it off. this process is known as MOLTING.Crayfish molt because as their size grows, they must shed their hard exoskeletons and grow new, larger ones. A crayfish molts six to ten times throughout its first year of existence.Molting normally takes only a few minutes. On the back side, the crawfish's brittle exoskeleton breaks between the carapace (head) and abdomen (tail), and the crawfish normally retreats by tail flipping.hence autotomy and regeneration go along each other in crayfish.

Describe how the lactic acid produced in muscle cells enters the blood
Answer:
Explanation:
Fast-twitch muscle also uses glycolysis to produce energy, but it skips harvesting energy from pyruvate, a process that takes oxygen. Instead, pyruvate gets converted into a waste product, lactic acid, and released into the bloodstream
Answer: Lactic acid is produced in your muscles when you perform strenuous exercise. It’s produced mainly in muscle cells and red blood cells when the body breaks down carbohydrates for energy when oxygen levels are low. These levels decreases during intense exercise or when a person has an infection or disease.

Imagine that fully functioning kidneys have been successfully created through bioengineering. What data analysis would measure the effectiveness of bioengineered organs in improving access to organ transplants among diverse groups of people, and what evidence would be needed to demonstrate that bioengineered organs have improved access
Answer:
The correct data analysis and evidence is:
Analysis: Compare the percentage of different ethnic groups who receive kidney transplants before and after bioengineered kidneys are available.
Evidence: A greater percentage of African Americans, Asians, and Pacific Islanders, and Hispanic/Latinos receive transplants after bioengineered kidneys are available compared to before
Explanation:
Bioengineered organs may be used to repair organs that have been destroyed. If the bioengineered organs are identical to the initial ones, transplantation rejection may be reduced.
So, to assess the effectiveness of organ donation adoption in people of various ethnicities, we should compare the percentage of people of various ethnicities receiving organ transplants before and after bioengineered organs became viable, and look for signs of a higher percentage of people of various ethnicities receiving organ transplantation after bioengineered organs became available.

Plan an investigation using dialysis tubing to determine the effect of temperature on the
activity of the enzyme amylase.
Answer:
To place the enzyme in different temperature.
Explanation:
In order to determine the effect of temperature on the activity of the enzyme amylase, we have to place the enzyme amylase in different environment having different temperatures. That environment which increases the activity of enzyme is considered suitable temperature for the enzyme and the temperature at which the activity of enzyme amylase is minimum is considered as bad temperature for the enzyme. For determining the temperature, we have to place the enzyme in different temperature.

Accept/Reject: Increased parasympathetic impulses to the adrenal medulla would result in cortisol release from neuroendocrine cells to initiate the short-term stress response g
Answer:
Accept.
Explanation:
I accept the statement that increased the impulses of parasympathetic to the adrenal medulla would result in the release of cortisol from neuroendocrine cells to initiate the short-term stress response. The cortisol provides glucose to the body from protein stores through the process of gluconeogenesis in the liver. This energy can help the person to fight against stressor and in avoiding stress. The neuroendocrine system produces the necessary response toward the stress through the secretion of cortisol, which is used to maintain the body's homeostasis.
