C
Explanation:
Does every gene combination show up in the offspring?
Answer:
Answer!
Explanation:
Okay so, genes come in different varieties; which are called allele. somatic cells contain two alleles for every gene, with one allele provided by each parent of an organism. BUT, an allele that is hidden, or not expressed by an organism, can still be passed on to that organism's offspring and expressed in a later generation.
During meiosis I, chromosomal pairs randomly align along the metaphase plate. Each chromosome pair member carries one allele for each gene. Every gene combination shows up in the offspring.
Chance determines which of the 23 homologous pairs of both parents' chromosomes are inherited. The possible combinations of 23 chromosomal pairs total 8,324,608. As a result, the chromosomal combinations of two gametes are almost never identical.
Actually, each parent has two distinct gene pools. Additionally, only half of each parent's DNA is passed on to their offspring. and that the randomness of the portion that is passed down. All of these factors work together to guarantee that every child has a distinct collection of genes.

describe the climate in coastal area near a warm ocean current
Answer:
The climate in coastal areas near a warm ocean current has higher temperatures as its moving away from the equator. The warm ocean currents cold water sinks which then allows light warm water to flow to the opposite direction usually away from the equator.
Explanation:
I would try putting in your own words and your own twist but hopefully this helps
The climate in coastal area near a warm current will warm and rainy. The coastal regions will be maintained in a moderate temperature by warm current
What is warm ocean current?
Warm currents are heat transferring wind flowing from ocean parallel to the tropical and sub-tropical regions. Warm ocean current results in summer rainfall in the surrounding areas.
North Atlantic drift and Canary currents are examples of warm ocean currents. They are responsible to bring a moderate temperature level in coastal areas.
Warm ocean currents may sometimes mix with cold currents creating foggy weather in the near areas. Thus cold and dry climate may result in that areas.
Therefore, in general, warm ocean currents make the surrounding coastal areas in a moderate temperature with summer rainfall.

After many years of normal function, a cell begins producing different proteins than it produced before. Propose two different explanations for this change.
Answer:
Explanation:
In order to produce different proteins, mutations must occur in the genetic material of the cell. We distinguish gene and chromosome mutations. Mutations in the level of genes are called point mutations because only one to several nucleotides are changed. These processes are known as deletion, insertion, and substitution. Mutations can also appear in chromosomes altering their number and structure. There are four types of mutations: deletion, duplication, inversion, and translocation.
Cells are the functional unit that has a specific activity to perform. The alteration of the cell function can be due to gene or chromosomal mutations.
What are gene and chromosomal mutations?A change in the sequence of the DNA of the gene causes gene mutation and affects the gene or the part of the DNA of the chromosome. They occur in a single place and are called point mutations.
The point mutation is the alteration, addition, deletion or inversion of the single nucleotide base pair of the gene.
The chromosomal mutation affects the whole chromosome and alters the shape and size of the chromosomes. It leads to the increase or the decrease of the ploidy and structural shape.
Chromosomal mutation can be due to translocation, deletion, inversion and duplication of the chromosomes. Their increase or decrease affects the genome as a whole.
Therefore, alteration of the cell can be due to chromosomal or gene mutation.

the energy role responsible for capturing the energy from the sun and turning it into food is a
A. producer
B. Consumer
C. Decomposer
Answer:
A. Producer
Explanation:
The primary source of energy for almost every ecosystem on Earth is the sun. Primary producers use energy from the sun to produce their own food
Answer:
Hi, there the answer is A. producer
Explanation:
All food chains start with energy from the sun. This energy is captured by plants. Thus the living part of a food chain always starts with plant life and ends with an animal. Plants are called producers because they are able to use light energy from the sun to produce food (sugar) from carbon dioxide and water.
The products of the glycolysis of one molecule of glucose can drive the citric acid cycle
Answer:
Since glycolysis of one glucose molecule generates two acetyl CoA molecules, the reactions in the glycolytic pathway and citric acid cycle produce six CO2 molecules, 10 NADH molecules, and two FADH2 molecules per glucose molecule
The products of glycolysis alone are not sufficient to directly drive the citric acid cycle (also known as the Krebs cycle or the tricarboxylic acid cycle).
However, the output of glycolysis, specifically pyruvate, is a crucial substrate that enters the mitochondria, where it undergoes further processing before entering the citric acid cycle.
The energy carriers, specifically NADH and FADH2, play a crucial role in driving the electron transport chain, the final step of cellular respiration.
The electron transport chain uses the energy from NADH and FADH2 to generate a large amount of ATP through oxidative phosphorylation.
Thus, while the products of glycolysis do not directly drive the citric acid cycle, they contribute to the overall energy production and supply the necessary substrates, such as acetyl-CoA, which is essential for the initiation of the citric acid cycle.

Which change would cause an increase in the size of a population?
Answer:It would be a migration
Explanation:
The answer is migration. It is described as the movement of people from place to place and permanently at the new location.
Similarly, migration will be seen growing old in prosperous areas and boom it in bad ones. Most nations and areas experiencing populace lower accomplish that specifically because of natural change (the distinction among births and deaths), at the same time as areas which advantage populace accomplish that specifically because of extra-migration.
What are the effects of migration in the area? Migration has an effect on the populace of the 2 unique areas. It will increase the populace of the place (new place), in which human beings migrate on the lookout for process possibilities, and reduce the populace of the region in which human beings migrate from. The charge of populace boom is the charge of herbal boom blended with the results of migration. Thus the excessive charge of the herbal boom may be offset via way of means of a massive out-migration, and a low charge of the herbal boom may be countered via way of means of an excessive stage of in-migration.Hence clear that migration change would cause an increase in the size of a population.

Explanation:
what is a non example of crystallization
Answer:
Microscopically, a single crystal has atoms in a near-perfect periodic arrangement; a polycrystal is composed of many microscopic crystals (called "crystallites" or "grains"), and an amorphous solid (such as glass) has no periodic arrangement even microscopically.
Most inorganic solids are not crystals but polycrystals, i.e. many microscopic crystals fused together into a single solid. ... The third category of solids is amorphous solids, where the atoms have no periodic structure whatsoever. Examples of amorphous solids include glass, wax, and many plastics.
In condensed matter physics and materials science, an amorphous (from the Greek a, without, morphé, shape, form) or non-crystalline solid is a solid that lacks the long-range order that is characteristic of a crystal. In some older books, the term has been used synonymously with glass.
Explanation:
This chapter highlights mesocrystals as an interesting example of particle‐mediated, non‐classical crystallization processes. Mesocrystals — the shortened name for mesoscopically structured crystals — are superstructures composed of nanoparticles, being arranged three‐dimensionally in crystallographic register. Mesocrystals are often only intermediate structures in a non‐classical crystallization pathway leading to a final single crystal by nanoparticle fusion. Therefore, they are difficult to detect. Although mesocrystals were initially described for synthetic systems, recent investigations have revealed an increasing number of bio‐mineral systems which appear to be mesocrystals, but which so far have been considered to be single crystalline, including nacre and sea urchin spines. This chapter briefly defines non‐classical crystallization processes, provides some examples of synthetic mesocrystals and mesocrystals in biomineralization, and attempts to provide some insight into their formation mechanisms, despite their being as yet largely unexplored.
