Answer:
One benefit of sexual reproduction is that your (or whoever is mating) genes will be passed on to your (their) children. If you want a specific trait to show (for example, in horses), then the two horses (say, long legs) with long legs would be bred together to get a horse with longer legs.
Claim Evidence Reasoning. Evaluate the following claim: Meiosis is different than Mitosis.
Answer/Explanation:
Yes, although they have similarities, meiosis and mitosis are different.
SimilaritiesMeiosis and mitosis are both types of cell division that results in the production of daughter cells.
They go through similar processes of prophase, metaphase, anaphase, and telophase.
DifferencesHowever, mitosis produces two genetically identical diploid daughter cells from a diploid parent cell.
Meiosis produces four genetically different haploid cells from a diploid parent cell.
There are two rounds of cell division in meiosis, and only one round in mitosis.
the diagram shown represents a dihybrid cross between two pea plants heterozygous for both seed color and seed shape.
what is the phenotypic ratio of the offspring?
A. 1:1:1:2:2:2:2:4
B. 1:3:3:9
C. 1:4
D. 4:12
Answer:
1:3:3:9
Explanation:
There are 12 yellow seeds, from which 9 are smooth and 3 are rough.
There are 4 green seeds, from which 3 are smooth and only 1 is rough.
Both the appearance and color of the seeds is something you need to look out for when dealing with phenotypes.
The phenotypic ratio of this dihybrid cross will be 1:3:3:9.
What is phenotype?The term phenotype simply refers to a trait that may be observed. Pheno means observe and is derived from the same root as "phenomenon." As a result, it's a sort of organism that can be seen, and it may relate to anything from a common characteristic like height or hair color to the presence or absence of disease.What is dihybrid cross?A mating experiment between two animals that are identically hybrid for two features is referred to as a dihybrid cross. A heterozygous organism is one that possesses two distinct alleles at the same genetic location, or locus.The cross between a homozygous pea plant with round yellow seeds and wrinkled green seeds is an example of a dihybrid cross.RRYY alleles are found in round yellow seeds, while rryy alleles are found in wrinkled green seeds.Hence the correct option is B.

What's the difference between inference and observation? Give examples of each.
Answer:
A inference is a conclusion reached on the basis of evidence and reasoning.
A observation is an act or instance of regarding attentively or watching
Explanation:
Example for a inference would be - lets say you notice someone isnt acting like theirself you may infer that their not having a good day or their not in a mood
Observation example- when your doing a lab for science you may observe the different types of utensils or the effects of the object you use like oh this is blue or something
Why is there limited vegetation in the tundra?
Answer:
Frigid temperatures, etc.
Explanation
The tundra has very low temperatures and a layer of permafrost over the soil. It has characteristics similar to the desert and it also has a short summer and a long, freezing winter. Therefore, there are not many flora variations that can thrive in that biome.
Answer:
The tundra experiences little rainfall, which makes the soil devoid of nutrients. The soil is permafrost, or permanently frozen. Both of these factors make it difficult for plants to grow in the tundra.

A cotransporter is something that moves two substances across a membrane, one passively and the other actively. The Na+/ K+ ATPase transports sodium and potassium ions across the plasma membrane against their concentration gradients. This pump is not considered a cotransporter because
Answer:
both ions are transported actively
Explanation:
If both ions are being transported against their concentration gradients, then they are both being transported by active transport, as it requires energy.
A co-transporter moves two substances across the membrane, one passively and one actively. But in this case neither ion is moved passively, so it cannot be considered a cotransporter

2. The thread-like chromosomes are spread
throughout the nucleus in the form
Answer:
When the cell is not dividing, the genetic material is loosely dispersed throughout the nucleus in a threadlike form called chromatin.
Explanation:
Chromatin is the thread-like chromosomes spread throughout the nucleus.
What are chromatin and its functions?Eukaryotic cells' nuclei include a combination of macromolecules called chromatin, which is made up of DNA, RNA, and protein. Heterochromatin (condensed) and euchromatin are the two types of chromatin. The main proteins that make up chromatin are termed histones, which act as bases for the DNA to wrap around to form the "bead-like" structures known as nucleosomes.Functions of chromatin:DNA packagingTranscription regulationChromatin and DNA repair

Bats are common in Texas especially in rocky regions bats with longer hang claws have demonstrated higher fitness because of their ability to cling to rock while resting this adaptive on is becoming more frequent in the population.What mechanism of evolution is this
Answer:
Natural selection
Explanation:
Natural selection is the mechanism of evolution in which organisms evolve in order to adapt the changes in the habitat for their survival. Living organisms are naturally variable and adjust themselves according to their surroundings.
In the given example, bats in Texas evolve themselves with longer hang claws to adapt the rocky nature of the surrounding. These longer hang claws provide them the ability to cling to the rock, which is an adaptive feature of bats that is influenced by the environment.
Hence, the correct option is "Natural selection".

ATP
CoA
NAD
NADH
pyruvate
NAD +molecule
Explanation:
Krebs cycle and electron transport chain are important steps in cellular respiration.
In the Krebs cycle, there is a need of NAD+ molecule which is then in Krebs cycle reduced to form a NADH2 molecule.
NADH2 is also an energy currency. It , giving electron in electron transport chain and return to Krebs cycle as NAD+.
Now in the Krebs cycle, it is ready to take electrons again.

Answer:
the clear plastic bag is used for the sunlight penetration to allow photosynthesis to take place (i guess this is the answer I'm not sure tho but think about it) Black plastic bag would prevent the light penetration

Who wants brainliest? Answer those 2 questions
Answer:
This type of natural selection occurs when there are selective pressures working against two extremes of a trait and therefore the intermediate or “middle” trait is selected for. If we look at a distribution of traits in the population, it is noticeable that a standard distribution is followed: Example: For a plant, the plants that are very tall are exposed to more wind and are at risk of being blown over. The plants that are very short fail to get enough sunlight to prosper. Therefore, the plants that are a middle height between the two get both enough sunlight and protection from the wind.
This type of natural selection occurs when selective pressures are working in favour of one extreme of a trait. Therefore when looking at a distribution of traits in a population, a graph tends to lean more to one side: Example: Giraffes with the longest necks are able to reach more leaves to each. Selective pressures will work in the advantage of the longer neck giraffes and therefore the distribution of the trait within the population will shift towards the longer neck trait.
This type of natural selection occurs when selective pressures are working in favour of the two extremes and against the intermediate trait. This type of selection is not as common. When looking at a trait distribution, there are two higher peaks on both ends with a minimum in the middle as such: Example: An area that has black, white and grey bunnies contains both black and white rocks. Both the traits for white and black will be favored by natural selection since they both prove useful for camouflage. The intermediate trait of grey does not prove as useful and therefore selective pressures act against the trait.
