Plants have chloroplasts and mitochondria. What is the purpose of mitochondria when a cell already has chloroplasts?
To turn sugars into energy
To fight off infection
To help plants store water
To store vitamins
Answer:
To turn sugars into energy
Explanation:
[tex] \bf{ \underline{ \large{Functions \: of \: Mitochondria}}}[/tex]
Mitochondria are main sites of aerobic respiration. They are miniature biochemical factories where food stuffs are completely oxidised to carbon dioxide and water. The energy (ATP) produced in the mitochondria helps to perform various energy requiring processes. Because of the formation of ATP in mitochondria it is called power house of the cell.[tex] \bf{ \underline{ \large{Functions \: of \: Chloroplast}}}[/tex]
Photosynthesis: Light reaction (in thylakoids), Dark reaction (in stroma).Storage of starch.best answer gets brainiest
Answer: Warm air rises, creating a low pressure zone; cool air sinks, creating a high pressure zone. Air that moves horizontally between high and low pressure zones makes wind. The greater the pressure difference between the pressure zones the faster the wind moves. Convection in the atmosphere creates the planet's weather.

Translate the mRNA into the corresponding amino acids.
mRNA Molecule:
AUGAACCAUUCAGUAUGG
Amino Acid( fill) :
The corresponding amino acids would be
UACUUGGCAAGUCAUACC
The given mRNA sequence can be translated into the corresponding amino acid sequence as Methionine-Aspargine-Histidine-Serine-Valine-Tryptophan.
RNA ribosome translation is the process by which mRNA is translated into proteins. A ribosome is a cellular structure composed of proteins and rRNA. It is the site of translation, where codon codons are matched to amino acids and peptide bonds are formed between amino acids.
All mRNAs are degraded at a specific rate once they enter the cell’s cytoplasm. Some mRNAs are translated, some are stored for further translation, and some mRNAs are temporarily translational repressed.

Which of the following is not a potential result of a bottleneck event?
a. an increase in potential mates
b. a decrease in genetic diversity
an increase in inbreeding
d. an increased chance of extinction
C.
Answer:
A. An increase in potential mates
Explanation:
An increase in potential mates would not be a potential result of a bottleneck event because it would actually increase the population rather than kill them off.
HAVE A GOOD DAY!!!!
Event an increase in potential mates is not potential result of a bottleneck.
What is the bottleneck effect for example?The bottleneck effect is an extreme example of genetic drift that occurs when the size of a population is severely reduced.
Events like natural disasters (earthquakes, floods, fires) can decimate a population, killing most individuals and leaving behind a small, random assortment of survivors.

How should the members of a sample be chosen
Answer: They must be randomly chosen, meaning that each member of the larger population has an equal chance of being chosen. They must be large enough so as not to skew the results. The optimal size of the sample group depends on the precise degree of confidence required for making an inference. Simple random sampling is the basic sampling technique where we select a group of subjects (a sample) for study from a larger group (a population). Each individual is chosen entirely by chance and each member of the population has an equal chance of being included in the sample.

Answer:which of the following does not affect the gravitational force between the earth and sun
Explanation:
The following does not affect the gravitational force between the earth and the sun: the temperature that is listed in Option A as the temperature of the earth or the sun does not affect their masses or the distance between them.
What is the gravitational force?The force of gravity between two objects, such as the earth and the sun, is determined by two main factors: the masses of the objects and the distance between them, as there are many factors that have no role in this, such as temperature, rotation, magnetic fields, chemical composition, etc. The temperature of the sun may change, but its mass remains the same; the earth may rotate on its axis, but this does not change its mass or distance from the sun; and the magnetic fields of the earth and the sun also do not affect their masses.

What is a T-cell receptor?
Answer:
The T-cell receptor (TCR) is a protein complex found on the surface of T cells, or T lymphocytes,[1] that is responsible for recognizing fragments of antigen as peptides bound to major histocompatibility complex (MHC) molecules. The binding between TCR and antigen peptides is of relatively low affinity and is degenerate: that is, many TCRs recognize the same antigen peptide and many antigen peptides are recognized by the same TCR.

What are carnivores?A creature known as a carnivore mostly consumes meat or animal flesh. Predators are another name for carnivores. Prey refers to the living things that predators consume. The food web, which describes which creatures consume which other organisms in the wild, includes carnivores as a significant component. Trophic, or nutritional, levels are used to classify organisms in the food chain.
Three trophic levels exist. The lowest trophic level is comprised of autotrophs or creatures that make their own food. Algae and plants are some of these. The second trophic level is occupied by herbivores or creatures that consume plants and other autotrophs. The third trophic level is composed of carnivores. The third trophic level also includes omnivores, which include animals, plants, and fungi in their diet.
Because autotrophs make their own nourishment, they are referred to as producers. Consumers include omnivores, carnivores, and herbivores. The main consumers are herbivores. The primary consumers are omnivores and carnivores.
Carnivores frequently consume herbivores. Some devour other carnivores, while others consume omnivores. Tertiary consumers of other carnivores are classified as carnivores. Orcas, or killer whales, are a well-known illustration of tertiary consumers. Sea lions and seals are prey for killer whales. Carnivores that eat fish, squid, and octopuses are seals and sea lions.
Therefore, carnivores need more energy for hunting.

difference in charge across the thylakoid membrane that allows
a. the production of ATP.
b. the release of water molecules.
c. light to enter the chloroplast.
d. the conversion of 3-carbon molecules into higher-energy forms.
Answer:
a. the production of ATP
Explanation:
Photosynthesis is type of biosynthesis that produces glucose from the reactants sunlight, carbon dioxide and water. It happens in two phases of the chloroplast, the light-dependent and light-independent reactions. In a light reaction that stimulates photosystems, pigments such as chlorophyll absorb light energy at specific wavelengths. Here,
Light energy stimulates photosystem complexes formed from chlorophyll. Photosystem II then absorbs and transfers light to a reaction core. Water undergoes hydrolysis or splitting to yield an electron, a proton (H+) and oxygen. energy is passed along the electron transport chain, where it forms builds up H+ and an electrochemical gradient in the thylakoid spaceThese protons pass through the ATPase enzyme embedded within the membrane, into the stroma, generating ATP from ADP.NADPH is generated from NADP+
