Which structures are similar in function, but do not indicate that the organisms are related?
analogous structures
homologous structures
vestigial structures
transitional structure
Answer:
A
Explanation:
analogous structures
Analogous structures are similar in function but do not necessarily suggest that the organisms are related.
What are analogous structures?The term “analogous” is used to describe biological structures that have similar or analogous functions but are not of the same evolutionary lineage. This means that the same biological structures are used by the same species for the same purposes, but the species are from different evolutionary origins. This type of evolution is called convergent evolution.
For example, similar structures of different species might have similar or equivalent functions, even though they originated from a different evolutionary point of view.
The wings of birds and insects are similar organs. Both birds and insects have wings that allow them to fly. However, their wings come from different ancestors. This is an example of analogous structure.

Are coastal mangrove forests and commercial shrimp farms equal in their economic value to humans? i need help
Yes, they are very much capable in providing economic importance to the man as they are capable enough to provide resources to the humans. The largest vegetation found in the plants is helping to provide a big number of resources.
What is the reason of high vegetation in such areas ?The reason of higher vegetation in such areas is because of the direct sunlight on the trees and because of the large exposure of sun on the trees it makes the photosynthetic rate higher.
Mangrove forests are capable in providing the following resources :
1. provision of food and clean water
2. influence climate regulation
3. soil composition regulation
4. disaster risk reduction (regulating services)
5. recreational and spiritual space (cultural services).

Which of these is the primary site of protein synthesis?
Answer:
Ribosome
Explanation:
Ribosome is a sub cellular structure, that is involved in protein synthesis.
Mitochondria is a sub cellular structure, where cellular respiration takes place, therefore it is called the energy house of the cell.
Cytoplasm is a jelly like structure in which sub cellular structures are found.
Nucleus is the main part of the cell in which all cellular activity is controlled by.
It contains DNA and RNA.
Nucleus is mostly known for it's thread like structure that contains hereditary information which is passed from parents to offspring.

The primary site of protein synthesis is the ribosome, because the ribosome carries out the protein synthesis of both types, such as secretory proteins and cytoplasmic proteins.
What is the role of the ribosome?The ribosomes are present in both the prokaryotes and the eukaryotes in the cytoplasm, and in the case of the eukaryotes, some of the ribosomes are present on the rough endoplasmic reticulum. The main function of the ribosome is to carry out translation, which is the protein synthesis process, and the protein can either enter the other cell organelle such as the nucleus, be present in the cytoplasm, or exit the cell.

Water has the ability to dissolve salts and carry dissolved carbon dioxide. How does this action help the human body maintain homeostasis?
A.) Both are involved in providing energy to the cells.
B.) These materials can be cycled through the body.
C.) The body will be able to absorb materials it needs from the environment.
D.) Waste can be removed from the cells of the body.
Answer:
i think its D
Explanation:
Because homeostasis is to maintain the internal enviroment of an organsism body constant .
organs responsible for homeostasis :
lungs: keep the concentration of carbondioxide and oxygen constant
skin: regulates the body temperature
kidney: regulates the concentration of water and urea
liver : regulates blood sugar level
To maintain the same concentrations inside the cells as outside of them, the blood's water and mineral ion levels are regulated. By preventing too much water from entering or exiting the cells through osmosis. Thus, option D is correct.
What action help the human body maintain homeostasis?Your body makes use of hormones like glucagon and insulin to maintain homeostasis. Insulin is released to counteract this alteration if your blood glucose level is too high.
Insulin helps your body cells absorb extra sugar from your blood. Glucagon reacts immediately if your blood glucose level is low.
The neural and endocrine systems maintain homeostasis. A response to a stimulus known as negative feedback keeps a variable near to a predetermined value.
Therefore, Waste can be removed from the cells of the body by homeostasis.

What is reproduction cycle?It goes through four stages: menstrual, regenerative, proliferative, and secretory. The cycle duration is the time it takes from the first day of one menstruation to the first day of the following menstruation; most usual cycles last 28 days, but it can range from 21 to 40 days. Puberty and sexual maturity, the breeding season, the estrous cycle, postpartum sexual activity, and aging are all related to the reproductive cycle. Environmental, genetic, physiologic, hormonal, behavioral, and psychological variables all influence these components. Reproduction is a biological process in which an organism reproduces biologically similar offspring. Reproduction allows and guarantees species continuation generation after generation.

C
Alcoholic fermentation takes place, and during the Krebs cycle, CO2 is produced, creating pockets in the dough.
D
Alcoholic fermentation takes place, and the H2O byproduct of the electron transport chain vaporizes to create pockets in the dough.
Answer:
A. Alcoholic fermentation takes place and ethyl alcohol and CO2 gas are formed, creating pockets in the dough.
Explanation:
Alcoholic fermentation is a process carried out by certain organisms in the absence of oxygen. In this process, sugars such as glucose etc are broken down without oxygen into ethanol (alcohol) and carbon dioxide (CO2) by an organim called YEAST.
According to this question, Jose and Rema are making sourdough bread. The starter being fed has undergone fermentation (in the absence of oxygen).

True
Explanation:
The point where the separation of the DNA occurs is called the replication fork. Therefore, it is true.
What is a replication fork?The DNA double helix of a cell has been unwound and split into the replication fork, which is where DNA polymerases and other enzymes can work.
DNA helicases unwind DNA at locations known as origins during DNA replication, where synthesis will begin. The replication fork, so named because the two strands of DNA seem forked as they are unzipped apart, is a structure that is created while DNA helicase proceeds to unwind the DNA.
A replication bubble is created when the circular bacteria chromosome's double-stranded DNA is opened at the point of replication. A replication fork, a Y-shaped junction where double-stranded DNA is split into two single strands, is present at each end of the bubble. Therefore, it is true.
