Eukaryotic cells are enclosed in the membrane, and the nucleus is bound by a nuclear membrane. Major parts of the eukaryotic animal cell are the nucleus, cytoplasm, mitochondria, Golgi, ER, etc.
What are animal cells?Animal cells are eukaryotes that lack cell walls but have almost the same components as plant cells. The cytoplasm is the component of the cell where all the organelle lies.
The nucleus is the central organ that is involved in genetic replication and transcription and translation. Mitochondria are involved in the metabolic process and release of energy.
Golgi are involved in the packaging and transport of the proteins and ER produces proteins that are transported to the Golgi. Vacuoles though are present in small quantities they aid in the accumulation and elimination of the waste product.

Answer:
Biosphere is a part of the ecosystem
The correct statement about ecological organization is:
An organism is part of a community.The levels of ecological organization are a hierarchy of categories that go from the micro to the macro (and vice versa), showing us different dimensions of analysis of living beings.
These levels are: organism, population, community, ecosystem, biosphere and biome.
The community is the level made up of a set of organisms of different species, which interact with each other in a specific area.
This includes life forms of all phyla: animals, plants, fungi, bacteria, etc. .
But in turn organisms interact, and these interactions can prevent some very similar species from coexisting (competitive exclusion principle), or the presence of a predator can cause two competitors to remain in low density and therefore there are no exclusion.
Therefore, we can conclude that the organisms of any species (plant or animal) are part of a community and that they coexist in a defined space (the biotope) that offers the external conditions necessary for their survival.

a)
hlwhos on this Imao ??
Answer:
The correct labels of the three planes are -
a. axial or transverse plane.
b. sagittal plane
c.. coronal plane
Explanation:
The human body can be divided into three planes on the basis of anatomy - the sagittal plane, the coronal plane, and the transverse plane
A sagittal plane is a longitudinal plane that divides the human body in the left and right parts.
A coronal plane is an anatomical plane that divides the body vertically into the back and front, ventral or dorsal (to be more specific).
An Axial or transverse plane, it is the plane that divides in the upper part of the body and lower part of the body.
Thus, the correct answer is -
a. axial or transverse plane.
b. sagittal plane
c. coronal plane
A farmer in Minnesota plants some tomato seeds in early spring. She plants them outdoors in soil and adds water every day. A few weeks later, nothing has happened. What is the most likely reason the seeds have not germinated?
Answer:
Other factors could affect the reason the seed didn't germinate because under suitable conditions depending on the variety it should germinate within 5 to 10 days from planting. However, the most likely reason it didn't germinate must be the Temperature.
Explanation:
From the question above, the farmer lives in Minnesota and she planted between March and May, meaning the temperature was way cold which is not suitable for tomato. One other valuable point was she planting outdoor which could also affect the performance of the tomato seedlings. Planting in early spring doesn't necessarily mean bad as some seeds might thrive under conditions explained above. For tomato, depending on temperature because too high temperatures could also affect the viability of the seeds. In Minnesota in early spring, it would have been better if she planted indoors to raise the temperature before transplanting as a balanced night temperature is also important for the seed viability.
Some other factors to be considered for seeds to germinate:
1. Water
2. Type of the soil
3. Seed depth in the soil
4. Nature of seed coat
5. Oxygen
6. Light

Which of these changes to the cell would cause the greatest reduction in the activity of the catalase?
CHOICES:
#1 a return of pH to the normal range
#2 A decrease in the concentration of hydrogen and oxygen
#3 an increase in the concentration of hydrogen peroxide
#4 an increase or decrease in PH beyond normal range
Answer:
#3 an increase in the concentration of hydrogen peroxide.
Explanation:
The changes to the cell that causes the greatest reduction in the activity of the catalase would be - #3 an increase in the concentration of hydrogen peroxide.
Catalase enzyme is present in both plant and animal cells. The catalase is mainly found in aerobic organisms. The substrate for the enzyme is hydrogen peroxide which is broken down into oxygen and water.
The hydrogen peroxide is harmful to the cell and very reactive. Its buildup can kill the cellto breakdown the hydrogen peroxide, the catalase enzyme catalyzes it and convert it into water and oxygenincrease of the hydrogen peroxide leads to a reduction in the activity of the catalase.A single molecule of the catalase can break down 40 million molecules of hydrogen peroxide per minute.Thus, the correct answer is - #3 an increase in the concentration of hydrogen peroxide.

What are the different sizes of carbohydrates
Cellulose, starch, glycogen, and most sugars
The molecule pictured below produced a blue color when tested with Benedict’s reagent, a yellow color when tested with IKI, and a violet color when tested with Biuret reagent. Based on the structure shown below and these chemical results, what kind of biomolecule is this? the molecule a blue color with benedicts reagent.no color change that given molecule is not a simple carbohydrate
Answer:
The molecule is a protein
Explanation:
When the molecule was tested with benedict's solution and a blue color was formed, that actually meant there was no colour change because the colour of benedict's solution is blue. Benedict's solution is used to test for the presence of reducing sugar, which changes it's colour to green, orange, yellow or even red; the fact that there was no colour change shows the molecule is not a reducing sugar.
Yellow colour when tested with IKI (Iodine-potassium iodide) also shows no colour change. IKI reagent is used to determine the presence of starch, which gives off a dark-blue colour if starch is present. Hence, absence of this dark-blue colour or observation of a yellow/orange colour shows the molecules is not starch.
Biuret reagent is used to test for peptide bonds in a molecule. In the presence of a peptide bond, the biuret reagent changes colour from blue to violet. The amino acids in proteins are held together by peptide bond, hence the biuret colour change shows that the biomolecule is a protein.

Explanation:
. Name the cells that are produced by the testes and ovaries.
Answer and explanation:
In the female of the species the reproductive cells are the egg cells, and in the male the reproductive cells are the sperm. The male gonad, the testicle, produces sperm in the form of spermatozoa. The female gonad, the ovary, produces egg cells. Both of these gametes are haploid cells. The testes contain germ cells that differentiate into mature spermatozoa, supporting cells called Sertoli cells, and testosterone-producing cells called Leydig (interstitial) cells.

Which statement best compares and contrasts lipids and carbohydrates?
HURRY PLEASEE I HAVE TWO MINUTES JUST THE LETTER AWNSER
The correct answer is B. Both are used for energy storage, but only carbohydrates are used for short-term energy.
Explanation:
Carbohydrates and lipids are both biological macromolecules, which means they are essential for living organisms. Additionally, these are similar because they store energy. However, the type of energy they store is different.
Indeed, carbohydrates store short-term energy, which means carbohydrates are broken down a short time after ingested, and the energy in them is used. On the other hand, in lipids, the energy store is long-term energy, which means it is not consumed as fast as in carbohydrates. This occurs because lipids contain more energy. According to this, the correct statement is "Both are used for energy storage, but only carbohydrates are used for short-term energy".
Answer:
B
Explanation:
Both are used for energy storage, but only carbohydrates are used for short-term energy storage.
