Read the paragraph from the section "Pea Plants And The Punnett Square."
A pea plant could have one copy of the height gene that coded for "tall" and one copy of the height gene that coded for
"short." The tall allele is "dominant," and this means that it can mask the other allele. The short allele is called
"recessive." The allele combination of tall-short would result in a tall plant since the tall allele is dominant.
Which option is the BEST definition of the word "mask" as used in the paragraph above?

Answer:

1 so that all parts of the plants and animals Get Enough nutrients and oxygen

2 the pigment called haemoglobin makes it red

3 waste products such as urea will cause great harm to the body is not excreted

4 the heart pumps blood the blood contains nutrients and oxygen facial transported to other organs so that the cells can operate

5 transpiration is the loss of water by plants. it helps with cooling down the plant after photosynthesis. Just the Way We sweat

6the stomata opens and closes to allow water to pass through it therefore transpiration occurs

Answer:

Plants are autotrops

Animals are Heterotrops

Answer:

1. New chromosomes remain attached to cell membrane - Both

2. Proteins check for errors - Both

3. Starts at one place - Prokaryotes

4. Proceeds in two directions - Both

5. Copies of DNA condense into chromosomes that separate - Both

6. Starts at many places - Eukaryotes

Explanation:

The difference between prokaryotic and eukaryotic DNA replications is associated with the origins of replication, that is, the locations where replication starts. While in eukaryotic DNA, the origin of replication occurs in several places along the strands of DNA, replication in prokaryotic DNA has a unique origin of replication.

Replication of a cell refers to the formation of the two alike copies of DNA it is crucial for biological legacy, cell growth and division.

The process of replication in prokaryotes and eukaryotes somewhat contrasts from each other.

1. New chromosomes remain attached to cell membrane - Both in prokaryotes and eukaryotes.

In prokaryotes, the single circular chromosome remains attached to the cell also in eukaryotes chromosomes remain attached to the nuclear envelope.

2. Proteins check for errors - Both in prokaryotes and eukaryotes.

Although the process of formation of proteins is different proofreading occurs in both types of organisms.

3. Starts at one place - Prokaryotes.

Replication in prokaryotes originates from only one place while eukaryotic replication can occur from multiple positions.

4. Proceeds in two directions- Prokaryotes.

Replication in prokaryotes is bidirectional and advances in two directions.

5. Copies of DNA condense into chromosomes that separate - Both in prokaryotes and eukaryotes.

DNA condenses in the nucleoid which later gets separated.

6. Starts at many places - Eukaryotes.

In eukaryotic replication, the DNA strand has multiple sites of origin and the replication can occur at multiple positions.

To be pollinated, pollen must be moved from a stamen to the stigma. When pollen from a plant's stamen is transferred to that same plant's stigma, it is called self-pollination. When pollen from a plant's stamen is transferred to a different plant's stigma, it is called cross-pollination.

Answer:

Due to the industrial revolution, smoke caused the environment of the peppered moths to change to a darker/black color. This resulted in a higher prevalence of black peppered moths over white peppered moths.

Explanation:

The dark environment made it so black peppered moths had the favorable trait while the white moths, who previously had the advantageous trait due to old environments being light in color, now had a deletirous trait. Predators could now more easily see the light colored moths, so they were more likely to be killed than the dark colored moths, so more dark colored moths were able to reproduce. This lead to a larger prevalence of dark peppered moths.

During the Industrial Revolution, pollution darkened tree trunks in England. This favored dark moths, causing a decline in lighter ones.

The peppered moth's environment changed due to the Industrial Revolution in England during the 19th century. Prior to the Industrial Revolution, the trees in England were predominantly light-colored, and the majority of peppered moths were also light-colored, or "typica." However, as a result of industrial pollution, the bark of the trees darkened, becoming covered in soot and ash.

This created a selective advantage for the dark-colored peppered moths, or "melanics," who were better camouflaged against the darkened trees. The change in the moth's environment was caused by the burning of coal in factories, which released soot and other pollutants into the air, leading to widespread pollution and industrialization. This phenomenon is often cited as an example of natural selection in action, as the moths adapted to their changing environment through the evolution of their coloration.

There are 22 numbered pairs of chromosomes called autosomes. The 23rd pair of chromosomes are the sex chromosomes. They determine an individual's sex. Females have two X chromosomes, and males have an X and a Y chromosome.

This is how you know if a karyotype is male or female?

Answer:

Females have two X chromosomes, and males have an X and a Y chromosome.

Elements such as carbon can move through the environment and organisms in a cycle because living and nonliving things interact in ecosystem. The correct option is D.

An ecosystem is made up of all the organisms and the physical environment in which they live.

These biotic and abiotic elements are linked by nutrient cycles and energy flows. Photosynthesis introduces energy into the system, which is then incorporated into plant tissue.

Healthy ecosystems clean even our own water, purify our air, keep our soil in good condition, regulate the climate, recycle nutrients, and provide us with food.

They supply raw materials and resources for pharmaceuticals and other uses. They are the foundation of all civilization and the lifeblood of our economies.

Because living and nonliving things interact in an ecosystem, elements such as carbon can move through the environment and organisms in a cycle.

Thus, the correct option is D.

Amino acids for given RNA strand is Serine - Leucine - Cysteine - Aspartic acid - Leucine.

There are 20 amino acids that are present in nature and are necessary for a number of biological functions. Although the molecular structures of these amino acids vary, they all have a core backbone made up of an amino group, a carboxyl group, and a side chain. Each amino acid is distinct due to its side chain, which also gives it special characteristics and abilities. Hydrophobic, hydrophilic, acidic, basic, and aromatic side chains can all be divided into different categories. How amino acids interact with their surroundings and other compounds is determined by this classification. Amino acids for given RNA strand is Serine - Leucine - Cysteine - Aspartic acid - Leucine.

Dominant traits will always be expressed if any amount is there. Recessive traits will only be expressed if two are there.

Answer:

If a trait is dominant, then you will only have to have at least one parent with a dominant trait for the offspring to inherit the trait.

If a trait is recessive, then you will only need one parent with a recessive trait for the offspring to be able to inherit the trait.
