PLEASE HELPP!!! Brainiest answer :))) thanks sm

Answer:

D. N

Explanation:

Meiosis is a kind of cell division which produces daughter cells that are genetically different from the parent cell and have a reduced number of chromosomes (by half).

Meiosis occurs only in reproductive cells to produce gametes. If a diploid (2n) cell undergoes meiosis, a haploid (n) daughter cell will result. This means that the chromosome number has been reduced by half in order to maintain the chromosomal number of the next generation.

Mitosis only

OPTION A

Mitosis is simply the process of cell division.

Meiosis is the process of producing gametes (eggs and sperm), which is important for sexual reproduction.

Answer:

Pangaea

Explanation:

Alfred Wegener proposed that the continents were once united into a single supercontinent named Pangaea, meaning all earth in ancient Greek. He suggested that Pangaea broke up long ago and that the continents then moved to their current positions. He called his hypothesis continental drift.

[tex]\sf\purple{Pangaea}[/tex] was the name of the supercontinent in Alfred Wegener’s continental drift hypothesis.

Answer: Los descendientes de la primera generación filial tendrán un genotipo Aa y un fenotipo color blanco.

Explanation:

Un gen es un segmento de ADN que codifica para una proteína. Para cada gen, hay distintas versiones, conocidos como alelos. Por ejemplo, el gen que codifica para el pelaje tiene los alelos para el color blanco y para el color negro. Considerando que los organismos diploides tienen dos copias de cada gen (dos alelos), un alelo dominante solo necesita una copia para expresarse. Mientras que un alelo recesivo, necesita dos copias.

En este ejemplo, el borrego homocigota blanco tiene un genotipo (conjunto de genes) de AA ya que el color blanco es dominante y al ser homocigota indica que ambos alelos son iguales. El borrego homocigota negro tiene un genotipo de aa ya que se necesitan dos alelos recesivos para mostrar ese fenotipo (características visibles).

Los borregos producen gametos, los cuales son células sexuales (espermatozoide u óvulo) haploides, es decir que solo poseen un alelo de cada gen. Entonces el borrego AA solo produce gametos con genotipo A, mientras que el borrego aa solo produce gametos con genotipo a. Estos gametos son los que se cruzan, es decir que la descendencia solo puede tener un genotipo Aa (con un alelo de cada padre)

El genotipo Aa posee un alelo dominante A (que codifica para el color blanco) que enmascara los efectos de el alelo recesivo a (que codificaría para el color negro) Entonces, los descendientes de la primera generación filial tendrán un genotipo Aa y un fenotipo color blanco.

Answer:

In dim light, your pupil expands to allow more light to enter your eye. In bright light, it contracts. Your pupil can range in diameter from 1/16 inch (1.5 mm) to more than 1/3 inch (8 mm). Light detected by the retina of your eye is converted to nerve impulses that travel down the optic nerve.

Explanation:

Homologous evolution means divergent evolution.

it is a type of evolution in which different species have common ancestor. for example if we take members of one species and put them in different environments then it is observed that there is some changes in the species according to environment

analogues evolution means convergent evolution

Answer:

Similar traits can be either homologous or analogous. Homologous structures share a similar embryonic origin. Analogous organs have a similar function. For example, the bones in a whale's front flipper are homologous to the bones in the human arm.

The chart that was used to compare the price of graphic T-shirts to the quantity supplied is a: supply schedule.

Supply can be defined as the total quantity of goods or services that are demanded by consumers at a given price and period of time.

In Economics, there are two main types of chart that are used to illustrate the relationship between the total quantity of goods or services that are demanded by consumers and the total quantity of goods or services that were supplied by a manufacturer or producer and these include:

In this scenario, the chart that was used to compare the price of graphic T-shirts to the quantity supplied is called a supply schedule.

Answer:

Vacuoles are the first blank, while cell membrane is the second blank.

Explanation:

The release of water from the vacuoles causes a plant to wilt and droop; if the cells do not contain any water, the plant will wilt and droop.

Vacuoles are enclosed compartments in the solution that are filled with water, inorganic-organic compounds, and enzymes. It's a crucial organelle in the cell of a plant.

The cell wall, on the other hand, aids in the plant's structural preservation during times of stress.

Evolution

Explanation:

Answer

Along with decreasing rainfall comes rising temperatures. By 2050 the U.S. could be as much as 5.7°F warmer, and extreme weather events, such as heatwaves and drought, could be more intense and occur more frequently. As temperatures warm, evaporation increases, further decreasing water in lakes, reservoirs, and rivers.

Answer: The correct answer is zygote...blastocyst...embryo...fetus.

Explanation:

The zygote is the single cell that was the result of fertilization.

The blastocyst is the big ball of cells that was the result of differentiation and mitosis.

Then comes the embryo, and then finally, the fetus.

Answer:

RNA and DNA wouldn't be read in the proper order and would code for different proteins, with devastating consequences.

Explanation:

Directionality is important in DNA and RNA because it ensures that all transcription and translation occurs in an organized and uniform manner. Without directionality, the DNA and RNA machinery would get confused and read the nucleotides into the machinery backward, which would give the sequence an entirely different meaning.

Answer:

Adverse effect on the animals.

Explanation:

If the rabbit population suddenly shrank due to disease, it will adversely affected the population of eagle, fox and coyote because these animals depend on them through feeding. Eagle, fox and coyote feed on the rabbit so if the population of rabbit decreases, then there will be scarcity of food for these animals and as a result decrease occur in their populations so we can say that adverse effect occurs on the population of eagle, fox and coyote.
