NEED HELP ASAPP!!!! 1. Which of these is smaller: a cell or a protein?
Answer:
[tex]\boxed {\boxed {\sf Proteins}}[/tex]
Explanation:
Proteins are found inside the cell. There are proteins in the cell membrane and cytoskeleton, they act as enzymes inside the cell, and they are created inside the cell during protein synthesis at the ribosome.
Since proteins are part of the cell and are made inside the cell, the proteins must be smaller.
The size comparison between a cell and a protein depends on the specific cell and protein being considered. In general, cells are larger than proteins.
1. Cells: Cells are the basic building blocks of life and can vary in size depending on the organism and cell type. For example, a human red blood cell has a diameter of about 7-8 micrometers, while a typical animal cell can range from 10 to 30 micrometers in diameter.
2. Proteins: Proteins are biomolecules made up of amino acids and have a variety of functions in cells. Proteins can vary in size, with some being relatively small and others much larger. For example, insulin is a small protein consisting of two polypeptide chains, each about 21 amino acids long. In contrast, titin is the largest known protein and can contain over 38,000 amino acids.
Therefore, while cells are generally larger than proteins, it is important to consider specific examples to accurately compare their sizes.

A. Fish and Wildlife Service
B. International Union for Conservation of Nature
C. Department of Natural Resources
D. National Marine Fisheries Service
Answer:
d
Explanation:
Under the Endangered Species Act, National Marine Fisheries Service looks after marine wildlife. Therefore, option (D) is correct.
What do you mean by endangered species act?An organism that is in danger of extinction is known as an endangered species. There are two main reasons why species become threatened: loss of genetic diversity and habitat destruction.
The Endangered Species Act of 1973 was enacted with the intention of safeguarding biodiversity and other endangered species. The bill came after the Endangered Species Conservation Act of 1969, which was an extension of the 1966 bill.
The act's goal is to safeguard both species and "the ecosystem on which they depend." This implies that organic entities that are at risk for going wiped out due to people obliterating their normal living space for advancement should be observed.

Who was Albert Einstien and what was he known for ?
Here ya go , Fivez and marcus UwU
Answer:
Albert Einstein is a German-born physicist and scientist who has created many ideas and theories relating to the study of relative. He is famously known for creating the famous equation [tex]e = mc^{2}[/tex] (Energy equals mass times the speed of light squared).
He was involved in the help of creating nuclear powered- mechanisms (not for destroying things, but for helpful, everyday things). Matter has an inherent amount of energy to it, mass can be converted (under the right conditions) to pure energy, and energy can be used to create massive objects that did not exist previously. Nuclear fission takes place when a heavy atomic nucleus, such as uranium, breaks into two or more smaller pieces with the release of some energy. During this process some of the mass of the original atom is converted into energy in accordance with the equation [tex]e = mc^{2}[/tex].

In humans, the allele for unattached earlobes (E) is dominant. The allele for attached earlobes (e) is recessive. A woman who is heterozygous for this trait marries a man who has attached earlobes. What is the probability that this couple's child will have unattached earlobes?
Group of answer choices
A: 100%
B: 75%
C: 50%
D: 25%
The alleles are the alternative form of the genes. When a heterozygous is crossed with a pure recessive, then 50% of offspring will have unattached earlobes. Thus, option C is correct.
What is a dominant allele?Dominant alleles are the gene forms that are expressed chiefly in heterozygous and purebred conditions and repress the expression of the recessive genes.
The unattached earlobes (E) are dominant traits whereas the attached earlobes (e) are recessive traits that can only be expressed in purebred conditions.
The cross between the heterozygous woman and man with attached earlobes is attached to the image below. From the cross, it can be seen that half or 50% of offspring have attached earlobes while the rest 50% have unattached earlobes.
Therefore, 50% of offspring have unattached earlobes.

What would happen to an animal cell with an internal salt concentration of 10% if it were placed in a salt solution with a concentration of 30%?
O The water would move out of the cell and the cell would decrease in size.
O The water would move into the cell and the cell would increase in size.
O The salt would move into the cell and the cell would increase in size.
O The salt would move out of the cell and the cell would decrease in size..
Answer:
The water would move out of the cell and the cell would decrease in size.
Explanation:
This question is depicting OSMOSIS, which is the movement of water from a region of high concentration (low solute concentration) to a region of low concentration (high solute concentration) across a semi-permeable membrane. This movement is caused when a concentration gradient forms between the two sides of the membrane.
In this case, an animal cell contains an internal salt concentration of 10% while the salt solution has a concentration of 30%. This means that the animal cell is hypotonic (contains high water concentration) to the salt solution, hence, water would move out of the cell and the cell would decrease in size
Which will most likely cause a decrease in the predator population? an increase in prey populations 2. a decrease in prey populations 3. a decrease in decomposers 4. an increase in producers.
Answer:
[tex]\huge\boxed{\sf A \ decrease \ in \ prey\ population}[/tex]
Explanation:
Predators are those animals which hunt prey. Prey is the animals which is "hunted".
When the prey population is less (a decrease in prey population), There will not be more animals for "predators" to hunt and so, the competition of living will become more. Decrease in preys population would lead to a decrease in predator's population because many predators will die of hunger.

What might happen to a cell if its cell membrane fails to function properly?
Answer:
If cell membrane fails to function then the cell will not be able to perform its task properly. The organelles will stop working which means no more protein created, no more energy production in the mitochondria and no material comes in and out of the cell. Eventually the cell will die.
Your welcome
Answer:
If the cell membrane is unable to do its job properly, this can cause the cell to stop working properly. If many cells have bad cell membranes, the disease can affect an entire organ or even the whole body. In many of these cell membrane diseases, proteins within the cell membrane don't transport materials properly.

How is the principle of superposition helpful in determining the age of the earth? Justify your response in two or more complete sentences.
How is stratigraphy helpful in determining the age of the earth? Justify your response in two or more complete sentences.
please hurry and answer both of these questions, this is important and put your answer again in the comments, thank you and please hurry.
Explanation:
The principle of superposition states that "in an undisturbed sequence of strata, the oldest is usually at the bottom and the youngest on top of it".
Judging by this, we know that sedimentary rocks are arranged on top of one another. We can use this to determine relative age because we know for sure the oldest layers are at the base of the sequence and the youngest are on top.
ii. Stratigraphy deals with the relative way in which strata are deposited in sedimentary basins.
It is useful in determining age of rocks because, rocks in different localities can be correlated using stratigraphic principles.

3 redwood trees are kept at different humidity levels inside a greenhouse for 12 weeks. One tree is left outside in normal conditions. The heights of the trees are measured once a week. What is the independent variable? What is the dependent variable? What is the control group?
Answer:
The correct answer is -
The independent variable - Humidity levels
The dependent variable - Height
The control group - Tree kept outside of the greenhouse
Explanation:
In this study or experiment, the independent variable is the different humidity level as it is what is changed in the study to see its effect on the growth of the redwood tree. The independent variable is manipulated in the experiment to see the change or effect in the dependent variable occurs.
The dependent variable is the variable which \depends on the independent variable as the Independent variable manipulated the dependent variable is measured to the effect which is the height of the redwood trees here.
The control group is a groub of subjects that did not get the treatment that experiment group recieves as it is kept for analysing the deviation from the natural condition. The control group is the redwood trees that are kept in natural environemnt outside of the greenhouse.
How does the mitochondria help maintain homeostasis?
Answer:
Mitochondrial biogenesis and mitophagy are two pathways that regulate mitochondrial content and metabolism preserving homeostasis. The tight regulation between these opposing processes is essential for cellular adaptation in response to cellular metabolic state, stress and other intracellular or environmental signals.
Explanation:
Answer:Mitochondria produce energy for cells through respiration. Mitochondria also helps maintain the environment of the cell (homeostasis) to keep the best conditions for optimum function. This is achieved by the storage and release of free calcium.
Explanation:
Do you think it would be a good idea for a bumper car to ride minimum and maximum weight requirements for riders? Apply Newtons Second and Third Laws of motion in your response.
Answer:
No
Explanation:
Eache one have a variation of the inertia because of F=ma (Force= mass*acceleration).
And the third law: for every action (force) in nature there is an equal and opposite reaction, if the car is too heavy it will bump everybody away but also reflect to other cars, and the light car will reflect at high speed to other cars.
If a cell's MITOCHONDRIA were to stop working, what would happen to the cell right
away?
A. Materials would not be transported
B. Energy would not be produced
C. Proteins would not get made
D. The cell would not be able to stop things from getting in and out
Explanation:
If a cell's mitochondria was to stop working, energy would not be produced.
This is so because The Mitochondria as part of the cell is the power house of the cell, it produces or gives energy to the cell so if were to stop working, energy will not be produced.

Answer:
1. 0 chance (0%)
2. 2 chances (50%)
3. 4 chances (100%)
Explanation:
the way a punnet square works is that you basically multiply two genes. for example:
b b
B Bb Bb
b bb bb
then, if it's uppercase, it is dominant. if it's dominant, it will take over the recessive gene. if it was Bo, B being brown and dominant, and o being recessive and orange, then brown would take over. there are also cases with codominant but that's not in the question. feel free to ask me anything about this.
