Which best describes the relationship between two species and a niche?
If two species have the same niche, one species will always become extinct.
Two species are able to occupy the same niche in the same habitat.
Two species cannot occupy the same niche in the same habitat.
If two species have the same niche, one species will always move.
Answer:
If two species have the same niche, one species will always move.
Explanation:
In biology, ecological NICHE refers to how the species of an organism performs in its ecosystem i.e. its role. Niche includes the reproduction, feeding pattern, prey, etc. However, if there are two species occupying the same niche, one species will always move.
One of the species, usually the weak one, will always move because occupying the same niche by two species will inevitably lead to competition, which causes one of the species to go elsewhere when these resources are limited.
Answer:
C.) Two species cannot occupy the same niche in the same habitat.

Plants roots create holes and tunnels in the soil allowing infiltrations to happen more easily. However, if trees and plants are stripped way, the soil can become dry. What process will increase if trees and plants are absent in the area?
Answer:
This question lacks options, but it can be answered based on general knowledge. The answer is SOIL EROSION
Explanation:
Soil erosion is a process whereby the top layer of the soil gets washed away by certain agents including water (from excessive rainfall) and wind etc. According to this question, plants roots create holes and tunnels in the soil allowing infiltrations to happen more easily. This means that the presence of plants in a soil makes the soil permeable to water and air.
However, in the absence of any plant form on a soil; the soil become exposed directly to this agents, becomes less infiltrable due to low penetration by roots, becomes less compact and held together etc. All these occurrences promotes the process of SOIL EROSION to occur on such a soil more.
In tomato plants, the production of red fruit color is under the control of an allele RR. Yellow tomatoes are rrrr. The dominant phenotype for fruit shape is under the control of an allele TT, which produces two lobes. Multilobed fruit, the recessive phenotype, have the genotype tttt.

Explanation:
I hope this helps!
One important role that ocean waters have in heating Earth is to absorb and transport solar energy.
What is a ocean?The ocean is a major heat sink for the Earth, meaning it absorbs and stores large amounts of heat from the sun. Sunlight penetrates the surface of the ocean and is absorbed by the water, causing it to warm up. This warm water then circulates through the ocean, carrying heat energy from the equator towards the poles. The ocean's currents also help to distribute heat around the globe, affecting global climate patterns.
Additionally, the ocean plays a crucial role in regulating the temperature of the atmosphere through the process of evaporation. As the sun heats the ocean's surface, water molecules evaporate and rise into the atmosphere. This process releases heat energy into the atmosphere, which helps to warm the air.

Which statement about protein hormone synthesis is FALSE. First exclude the four statements that are true. Which statement about protein hormone synthesis is FALSE. First exclude the four statements that are true. The RNA used for protein hormone synthesis is a copy of the gene for the protein hormone. Protein hormones are synthesized on free ribosomes. The cell invests energy to move protein hormones through the cell. Protein hormones are packaged into vesicles for movement through the cell. Protein hormones often travel through the bloodstream in order to reach a target cell.
Answer:
The correct answer is - Protein hormones are synthesized on free ribosomes (false).
Explanation:
The majority of the hormones that are produced from endocrine glands are produced are steroids however some of the hormones are made up of peptide or proteins.
Protein hormone synthesis uses RNA, is a copy of the gene for this hormone, this is packaged into vesicles with the help of ER and Golgi bodies for movement through the cell and reaches to its target cell by traveling through the bloodstream. mRNA is transcribed from DNA in order to produce protein. These hormones are produced according to the mRNA coding from amino acids in the cell.

1. Smooth ER
2. Rough ER
3. Golgi apparatus
4. Lysosomes
B. Sites of protein synthesis
All proteins are synthesized by ribosomes in the cell. Some ribosomes float freely in the cytosol, while others are bound to the surface of the endoplasmic reticulum. Most proteins made by free ribosomes function in the cytosol. Proteins made by bound ribosomes either function within the endomembrane system or pass through it and are secreted from the cell. Which of the following proteins are synthesized by bound ribosomes?
A. Lysosomal enzyme
B. Insulin
C. ER protein
D. DNA polymerase
E. Ribosomal protein
C. Pulse-chase experiments and protein location
Scientists can track the movement of proteins through the endomembrane system using an approach known as a pulse-chase experiment. This experiment involves
the "pulse" phase: Cells are exposed to a high concentration of a radioactively labeled amino acid for a short period to tag proteins that are being synthesized.
the "chase" phase: Any unincorporated radioactively labeled amino acids are washed away and large amounts of the same, but unlabeled, amino acid are added.
Only those proteins synthesized during the brief pulse phase are radioactively tagged. These tagged proteins can be tracked through the chase period to determine their location in the cell.
The data below were obtained from a pulse-chase experiment in which cells were examined at different times during the chase period. The numbers represent the radioactivity (measured in counts per minute) recorded at each of the indicated sites. The higher the number, the greater the radioactivity.

4. Lysosomes: c. macromolecule digestion, e. autophagy
B) A. Lysosomal enzyme; B. Insulin; C. ER protein
C) c. phagocytosis
Explanation:
In eukaryotic cells, the smooth ER (smooth endoplasmic reticulum) is defined as a subset of the endomembrane system of the endoplasmic reticulum responsible for many cellular functions, including the synthesis of lipids and hormones (steroid hormones), the elimination of harmful metabolic compounds and the storage of calcium ions. The Rough ER is a series of connected flattened sacs that bound to the ribosomes and functions during the synthesis of proteins. The Golgi apparatus is another membrane organelle responsible for transporting, modifying, and packaging lipids and proteins. The lysosomes are also membrane organelles that are found in animal cells, these organelles contain digestive hydrolytic enzymes used to break down different types of molecules. Ribosomes are structures formed by both RNA and proteins which are found within all cells. The ribosomes play a major role during the synthesis of proteins, specifically during the translation from messenger RNAs (mRNAs) to proteins. These structures link amino acidic residues to form polypeptide chains. Finally, phagocytosis is a type of endocytosis where the cell engulfs a particle by using its plasma membrane, thereby producing a phagosome.

Horses with two Ov copies, OvOv, die soon after birth and are called white overo because they are completely white. Horses with no Ov copies are solid colored, ovov. The Leopard complex gene, Lp, shows incomplete dominance and controls white spotting. One Lp allele, Lplp, produces the leopard phenotype, in which there are spots everywhere. Two Lp alleles, LpLp, produce the fewspot phenotype, in which the horse is mostly white with colored spots.

Solid Horse with leopard phenotype. Leopard Horse with pintaloosa phenotype. Pintaloosa Horse with fewspot phenotype. Fewspot Suppose that 16 pairs of pintaloosa horses have one offspring per pair. How many of each phenotype would be expected
The question is incomplete. Here is the complete question.
In horses, the Overo gene, Ov, produces a white splotch pattern on the coat. The overo phenotype is seen only when a horse has one Ov copy, Ovov. Horses with two Ov copies, OvOv, die soon after birth are called white overo because they are completely white. Horses with no Ov copies are solid colored, ovov.
The Leopard complex gene, Lp, shows incomplete dominance and controls white spotting. One Lp allele, Lplp, produces the leopard phenotype, in which there are spots everywhere. Two Lp alleles, LpLp, produce the fewspot phenotype, in which the horse is mostly white with colored spots.
A horse that is both overo and leopard is called pintaloosa, and these horses are spotted with splotches. A horse that is overo and fewspot is considered fewspot because the white areas from Lp is indistinguishable from the white from Ov.
Suppose that 16 pairs of pintaloosa horses have one offpring per pair. How many each phenotype would be expected? Determine the number out of 16 expected for each phenotype. Only count phenotypes of offspring expected to live past one week of age.
overo:
white overo:
fewspot:
Answer: Overo: 2
White overo: 0
Fewspot: 3
Explanation: Pintaloosa is a "combination" of overo and leopard, so the pair's genotype is OvovLplp.
To cross a pair, use Punnet Square and to facilitate, use the square for each characteristics:
Punnett Square For overo and white overo:
Ov ov
Ov OvOv Ovov
ov Ovov ovov
Analysing this Punnett square, notice that there are 2 individuals who will carry the genotype for overo (Ovov) phenotype. So, 2 out of the 16 pair will have an overo phenotype.
Since white overo is recessive (ovov) and doesn't survive past birth, there will be zero horses with that phenotype.
Punnett Square For leopard and fewspot:
Lp lp
Lp LpLp Lplp
lp Lplp lplp
From this square, notice that there are 1 individual who is fewspot. However, a horse that is overo and fewspot is considered fewspot, so for the 16 pair, 3 out 16 will be fewspot.

How does the life process of a prokaryotic cell differ from a eukaryotic cell?
Answer:
There are several differences between the two, but the biggest distinction between them is that eukaryotic cells have a distinct nucleus containing the cell's genetic material, while prokaryotic cells don't have a nucleus and have free-floating genetic material instead.Jul 11, 2019
Explanation:
There are several differences between the two, but the biggest distinction between them is that eukaryotic cells have a distinct nucleus containing the cell's genetic material, while prokaryotic cells don't have a nucleus and have free-floating genetic material instead.Jul 11, 2019
Answer: A prokaryotic cell has no nucleus, while a eukaryotic cell does. What that means is that since a prokaryotic cell has no nucleus, it significantly differs itself from a eukaryotic cell. The nucleus in the eukaryotic cell stores the Gene's, DNA, and information about the cell, while a prokaryotic cell has genetic material floating around in it. This is the main differentiator of the two, however there are other ones.
