In what stage of meiosis is crossing over most likely to occur?
Prophase I
Anaphase II
Metaphase I
Prophase II
Answer:
Prophase I
Explanation:
When chromatids "cross over," homologous chromosomes trade pieces of genetic material, resulting in novel combinations of alleles, though the same genes are still present. Crossing over occurs during prophase I of meiosis before tetrads are aligned along the equator in metaphase I.
By meiosis II, only sister chromatids remain and homologous chromosomes have been moved to separate cells. Recall that the point of crossing over is to increase genetic diversity. If crossing over did not occur until sometime during meiosis II, sister chromatids, which are identical, would be exchanging alleles. Since these chromatids are identical, this swap of material would not actually change the alleles of the chromatids.

Answer:
[tex]\boxed{\tt C. \ Around }[/tex]
Explanation:
Let's break down the word.
Pericardial = peri- cardi - al
Peri-: (prefix) = around
Cardi: (root) = heart
-Al: (suffix) = pertaining to
Put the definition together.
Pericardial = pertaining to around the heart.
Therefore, the correct answer is C. Around

Kendra wishes to build a model of a carbohydrate molecule, ideally containing as many monomers as
Answer:
Assuming this has something to do with sets?... The answer would be polysaccharides.
Explanation:
Polysaccharides are sets of carbohydrates formed by the union of hundreds and miles of carbohydrate molecules, the set having the largest possible number of monomers.
Carbohydrates are energetic molecules that are also present as structural molecules, being essential for the maintenance and functioning of the organism. Carbohydrates can be presented in monosaccharide, disaccharide and polysacride sets.
Which of these changes would most likely lead to exponential growth in
population?
an increase in the predation on the population
a decrease in the habitat size of the population
an increase in the amount of food available to the population
a decrease in the amount of water available to the population
Answer:
It is an increase in available food amount.
Explanation:
An increase in predators would result in the prey species dying off. A decrease in habitat size would result in the species not having a place to live or hide from predators. A decrease in amount of available water would make the species die of dehydration.
The prey species would disappear as there would be more predators. The species wouldn't have a place to reside or hide from predators if the habitat's size shrank.
What is the exponential growth?If the amount of water available decreased, the animal would become dehydrated and die.
An exponential function's curve is created by a pattern of data called exponential growth, which exhibits higher increases over time.
Linear growth, which is additive, and geometric growth can be contrasted with exponential growth, which is multiplicative.
Therefore, The prey species would disappear as there would be more predators. The species wouldn't have a place to reside or hide from predators if the habitat's size shrank.

a type of organism that can occupy the first trophic level of a food chain but not perform
photosynthesis
Autotrophs are organisms that can occupy the first trophic level of a food chain but not perform photosynthesis.
What type of organisms occupies the primary trophic stage?Producers make up the primary trophic stage. Manufacturers, also called autotrophs, make their very own food and no longer rely on every other organism for vitamins. most autotrophs use a process referred to as photosynthesis to create food (a nutrient called glucose) from daylight, carbon dioxide, and water.
Autotrophs no longer consume different organisms, they are the primary trophic degree. Autotrophs are eaten by means of herbivores, organisms that devour plants. Herbivores are the second trophic degree.

what property of water allows the pure water to stick to the penny?
Answer:
This cohesion property results in surface tension. Because water molecules at the surface of the water puddle attract more to one other than they do to the air molecules above them, they cling together and form a dome shape on the coin. Surface tension prevents the water molecules from falling out and spilling.

6. How are cubs raised within the pride?
Answer:
In a pride, lions hunt prey, raise cubs, and defend their territory together. In prides the females do most of the hunting and cub rearing. Usually all the lionesses in the pride are related—mothers, daughters, grandmothers, and sisters. Many of the females in the pride give birth at about the same time.
The cubs are born outside the pride. But as they grow, the male lion hunts prey delivers the food and raises cubs. Female lion also performs the activity of hunting in order to rear cubs.
What are Cubs?Cubs may be defined as the young offspring of the lion which usually require parental care.
During this time, the lioness keeps their cubs hidden from all forms of animals as well as her own pride in order to ensure the security of their cubs.
As time passes, cubs transform into adults. Now it is the time when a male lion, female lion, and adult cubs defend their territory together.
Therefore, it is well described above.

What is the carbon cycle?
The carbon cycle is a biogeochemical cycle by which the carbon tarn=fer from one body to another body. It also transfers into different types of atmospheres. The different atmospheres are stratosphere, geosphere, hydrosphere, etc.
Maintaining a steady carbon balance and temperature on our planet is essential. The carbon cycle naturally regulates carbon, the element that gives the Earth its life. Without it, the Earth would be frozen.
The most prevalent element in biological products and numerous minerals, including limestone, is carbon. The amount of carbon dioxide in the atmosphere decreases or increases with the carbon cycle.
