#: Why do you think egg cells are large and sperm cells are small?
HELP!!! ASAP
Answer:
Because eggs contain amost all organelles, and materials for growth. A sperm only contains haploid chromosome and certian mitochondria for movement.
Explanation:
:)
The egg, like a sperm cell, has a nucleus with half the number of chromosomes as other body cells. Apart from a sperm cell, the egg contains a large amount of cytoplasm, or cell contents, which is why it is so large.
What are gametes?A gamete is an animal or plant reproductive cell. Female gametes are known as ova or egg cells in animals, while male gametes are known as sperm.
Ova and sperm are haploid cells, with only one copy of each chromosome in each cell. A sperm and an ovum combine during fertilization to form a new diploid organism.
Because the formation of the egg begins before birth inside the developing body of a female embryo and is not completed until the egg is fertilized by a sperm many years later, the egg cell is much larger than the sperm cell.
The sperm cell is small in size because its primary function is to swim to the egg cell.
Thus, the egg cells are large and sperm cells are small.

How is the difference in the walls of the atria and ventricle related to the different functions of the atria and ventricle?
Answer:
The atria are thin-walled sacs that receive blood from the body or lungs, while the ventricles have a thick muscular wall because they must pump the blood with greater pressure than the atria.
Explanation:
In the human heart, the atria and ventricles are responsible for handling blood and have different structures and function.
The atria are thin-walled sacs located at the top of the ventricles and their function is to receive the blood that comes from the whole body —right atrium— or from the lungs —left atrium— to pass it to each ventricle through the atrioventricular valves, which does not require much pressure. On the other hand, the walls of the ventricles are made up of a thick layer of muscular tissue, since the pressure with which they must pump the blood -towards the lungs or to the entire organism- is greater than that of the atria.The structure of each chamber of the heart is configured to be able to fulfill the specific function that they possess.
1. Luca made the following chart for Earth's four basic movements, what needs to be correct on his chart?
Rotation Speed Revolution Speed Solar System Speed Milky Way Speed
0.3 miles/sec
18.5 miles/sec
370 miles/sec
150 miles/sec
The rotation speed and revolution speed should be switched
The revolution speed and solar system speed should be switched
The rotation speed and Milky Way speed should be switched.
The solar system speed and Milky Way speed should be switched.
Answer:
The solar system speed and Milky Way speed should be switched.
Explanation:
The speed of the Earth is with respect to how it moves around it's own axis (rotation speed), the Sun (revolution speed), solar system (solar system speed), and the milky way galaxies (milky way speed) etc.
According to this question, Luca made a chart for this Earth's four basic movements. The chart with their respective speed are as follows:
Rotation Speed - 0.3 miles/sec
Revolution Speed - 18.5 miles/sec
Solar System Speed - 370 miles/sec
Milky Way Speed - 150 miles/sec
Luca, however, made a mistake in his chart.
- The rotation speed of the Earth around its axis is correctly 0.3miles/sec
- The revolution speed of the Earth around the sun is correctly 18.5 miles/sec
- The solar system speed of the Earth i.e. around the solar system is about 150miles/hour
- The milky way speed of the Earth i.e. around local group of galaxies is about 370miles/hour.
Based on the comparison of Luca's chart and correct speed illustration, THE SOLAR SYSTEM SPEED AND MILKY WAY SPEED SHOULD BE SWITCHED.
Give an example of how Eubacteria can be beneficial. Explain. Please help me.
Answer:
Some bacteria are good for you, including the bacteria in your digestive system, or gut. These bacteria help to break down food and keep you healthy. Other good bacteria can produce oxygen are used to create antibiotics. Bacteria are used in food production to make yogurt and fermented foods.
An example of how Eubacteria can be beneficial is that these bacteria fix nitrogen for soil that can be used by living beings.
What are eubacteria?The bacteria in your gut and digestive tract are among the beneficial bacteria. These microorganisms aid in the digestion of food and promote good health. To make antibiotics, other beneficial microorganisms that can also produce oxygen are employed. Yogurt and other fermented foods are produced using bacteria in the food industry.
Oxygen, carbon, nitrogen, and phosphorus that living things like animals and plants cannot use can be converted by eubacteria into usable forms. In the soil, they fix the nitrogen that is present in the air.
Therefore, Eubacteria can help the environment by fixing nitrogen into the soil so that living things can use it.

a cell was poisoned by a substance that destroyed all of its mitochondria. which cell transport processes would be able to still continue?
Answer:
Nothing
Explanation:
If a cell's mitochondria were destroyed it would die. Mitochondria are the power houses of the cell and without energy, necessary reactions could not take place .
If a mitochondria stopped working the cell would not have its respiratory function such as to use carbon dioxide, water, and energy in which the cell needs to survive so the cell would eventually stop moving and slowly die out with no nutrients and energy.

17. Which of the following best describes how amino acids affect the tertiary structure of a
protein?
a) The number of amino acids determines the tertiary structure of the protein.
b) The interactions of the different R-groups with other R-groups and with their environment
determine the tertiary structure of the protein.
c) The R-group of the last amino acid that is added to a growing polypeptide chain
determines the next amino acid that is added to the chain.
d) The sequence of the amino acids in the polypeptide chain determines the protein's
primary structure but has no effect on its tertiary structure.
Answer:
It is B
Explanation:
I had this question on my test last week
The tertiary structure of the protein is determined by the interactions of the different R-groups with other R-groups and with their environment in the protein (Option B).
An R-group (also called variable group) is a side chain that is attached to the α-carbon of the amino acids, the building blocks of proteins.The linear sequence of amino acids within a protein is the primary structure of proteins. The second structure of proteins is determined by the pattern of hydrogen bonding in the peptide backbone. The most common secondary structures of the proteins are alpha-helices and beta-sheets.The protein tertiary structure is the 3D (tridimensional) shape of the protein, which is due to interaction among R groups of amino acids and with their environment.The most common tertiary structures of the proteins are globular and fibrous structures.Finally, the quaternary structure of the proteins is determined by the interaction of several protein chains or subunits.In conclusion, the tertiary structure of the protein is determined by the interactions of the R-groups and with their environment in the protein (Option B is correct).

Essential nutrients move through a cell membrane by both passive transport and active transport. Which of the following correctly describes the transport of materials across a cell membrane?
Answer:
This question lacks options, the options are:
A). Active transport requires chemical energy to move nutrients from areas of low concentration to areas of high concentration.
B). Passive transport requires chemical energy to move nutrients from areas of low concentration to areas of high concentration.
C). Active transport moves nutrients from areas of high concentration to areas of low concentration without the use of chemical energy.
D). Passive transport moves nutrients from areas of low concentration to areas of high concentration without the use of chemical energy.
The answer is A
Explanation:
Transport of materials across a cell occurs via passive transport or active transport depending on whether energy input is required or not to facilitate the movement.
- Passive transport is the transport of materials e.g nutrients from areas of high concentration to areas of low concentration i.e down a concentration gradient, without the use of chemical energy (ATP).
- On the other hand, active transport requires chemical energy (ATP) to move nutrients from areas of low concentration to areas of high concentration i.e against concentration gradient.
In the process of photosynthesis, plants use carbon dioxide (CO2), water (H2O), and light energy to produce a sugar (C6H12O6) and oxygen (O2). In the process of aerobic respiration, animals and plants release energy from sugar and oxygen and produce carbon dioxide and water. The chemical equations that describe these reactions look like this: 6CO2 + 6H2O + light C6H12O6 + 6O2 C6H12O6 + 6O2 6CO2 + 6H2O + energy
The question is incomplete, the complete question is;
In the process of photosynthesis, plants use carbon dioxide (CO2), water (H2O), and light energy to produce a sugar (C6H12O6) and oxygen (O2). In the process of aerobic cellular respiration, animals and plants release energy from sugar and oxygen and produce carbon dioxide and water. The chemical equations that describe these reactions look like this:
photosynthesis: 6CO2 + 6H2O + light ---> C6H12O6 + 6O2
cellular respiration: C6H12O6 + 6O2 ----> 6CO2 + 6H2O + 36 ATP
How do these equations explain why the total amount of O2 and CO2 remains the same?
Answer:
See explanation
Explanation:
If we look at photosynthesis and cellular respiration, we will realize that the both are complementary processes. The product of one process is the input material for the other process.
Respiration and cellular respiration helps to balance the amount of O2 and CO2 in nature because photosynthesis takes in CO2 and releases oxygen while cellular respiration takes in oxygen and releases CO2. This maintains the delicate balance between the both gases in nature.
