The endosymbiotic theory provides an explanation for the origin of chloroplasts. Which trait of chloroplasts supports this explanation? A. Chloroplasts do not reproduce. B. Chloroplasts rely on proteins that are made by the cell. C. Chloroplasts are larger than prokaryotic cells. D. Chloroplasts have their own DNA.
Answer:
D
Explanation:
i think its D because chloroplasts can reproduce so option A is not valid they are the same size as prokaryotic cells and they donot rely on proteins that are made by the cell..but most of all they have there own DNA.

In an experiment to investigate a factor affecting photosynthesis, a leaf of a potted plant which had been kept in the dark overnight was covered with aluminum foil as shown in the diagram below 1. Aluminium foil The set up was kept in sunlight for three hours after which a food test was carried out on the leaf. (a) Which factor was being investigated in the experiment? b) What food test was carried out? (i) State the results of the food test (ii) Account for the results in c (i) above
Answer:
Photosynthetic activity.
Explanation:
The photosynthetic activity of the plant was being investigated in the experiment and no photosynthesis will occur because the aluminium foil reflect 95% of sunlight. Starch test is the food test that was carried out in the experiment. Starch from plants is broken down into its constituent sugar molecules by the plant body in order to provide energy to the tissues so if there is no photosynthesis occurs, the plant body uses starch so decrease occur in the concentration of the starch molecules when the starch food test will occur.

The chemical forces that contribute to the stability of the DNA helix are (choose the best answer):______
a) hydrogen bonds van der
b) Waals interactions
c) disulfide bonds
The forces that contribute to the stability of DNA helix are hydrogen bonds. That is option A.
Deoxyribonucleic acid (DNA) is a molecule found within nucleus of cells which contains genetic information that is used by the organism for development.
A molecule of DNA is made up of four nitrogenous bases which include:
Adenine (A), Cytosine (C), Guanine (G), andThymine (T)The DNA helix is double which is made up of two linear strands that run opposite to each other and twist.
Hydrogen bond is defined as the intermolecular force that is capable of forming a dipole-dipole attractions.
The hydrogen bond that is formed between the nitrogenous base pair helps contributes to the stability of the DNA helix.
Therefore, the forces that contribute to the stability of DNA helix are hydrogen bonds.

Mitosis is a way of making more cells that are genetically the same as the parent cell. It plays an important part in the development of embryos, and it is important for the growth and development of our bodies as well. Mitosis produces new cells, and replaces cells that are old, lost or damaged.

Which of the following is not true of integrin? Question 4 options: Integrin molecules serve as stable, permanent anchors that anchor a cell to the extracellular matrix. Integrins undergo extensive conformational changes on binding to molecules on either side of the plasma membrane. Certain intracellular chemical signals can activate integrins from inside the cell, causing them to reach out and grab hold of extracellular structures. When integrin binds to the extracellular matrix, it stretches into an extended, activated state to attach to molecules on the inside of the cell.
Answer:
Integrin molecules serve as stable, permanent anchors that anchor a cell to the extracellular matrix.
Explanation:
Integrins are transmembrane protein receptors that attach the cell cytoskeleton to the extracellular matrix (ECM) in animal cells. These glycoproteins (integrins) are highly dynamic heterodimeric molecules that anchor cells in their position and transduce signals into and out of cells. Integrin-ligand binding activates signaling pathways that are involved in fundamental cellular functions including, among others, organization of the cell cytoskeleton, cell migration, regulation of the cell cycle, etc.
The statement i.e. not true is Integrin molecules serve as stable, permanent anchors that anchor a cell to the extracellular matrix.
The following information should be considered:

Is it possible to know the genotypes of the three children in generation III? _________________________ Should their shapes be shaded? ____________________________ Explain your answer to both questions
Answer: Some data related to your question is missing attached below is the data.
answer:
It is possible to know their genotypesthe shapes should be shaded as wellExplanation:
It is possible to know the genotypes of the Children ( three of them ) and their genotypes are ; Hh, Hh, Hh
Their shapes should be shaded as well and this because the (3) children posses the dominant allele H in their genotype composition .
Some records associated with your query is lacking connection underneath are the records.
It is feasible to recognize that their genotypes shapes have to be shaded as properly.
It is feasible to recognize the genotypes of the Children (3 of them) and their genotypes are; Hh, Hh, HhTheir shapes have to be shaded as properly and this is due to the fact that the kids possess the dominant allele H of their genotype composition.What are genotypes?Genotype is an individual's series of genes. The time period can also talk over with the 2 alleles inherited for a selected gene. The genotype is expressed whilst the records encoded withinside the genes' DNA are used to make protein and RNA molecules.

Biome Description Biome Name
This biome is characterized by long, cold winters. Plants living in this biome are adapted to the short summer growing season. Decomposition in this biome is slow, because of these low temperatures, high soil acidity, and a deep layer of needles from evergreen trees. ________________
In this biome, very little plant litter builds up on the ground because of the hordes of decomposers living here. Under these uniformly warm and humid conditions, the nutrients that are released by decomposers allow for quick uptake by producers, resulting in lush vegetation. ___________________
Although the average annual precipitation in this biome is quite high, rain falls only during certain times of the year. Grasses and widely scattered clumps of trees are the predominant vegetation, and they are well adapted to surviving alternating cycles of dry heat and heavy rains. _________________
Drought-resistant perennial grasses are the dominant vegetation in this biome, as there is sparse annual precipitation. Periodic natural fires, grazing, and drought typically eliminate most seedlings (which adds to the rich organic composition of the soil). Today, much of this land is devoted to farming, with annual crops such as corn and wheat replacing the natural perennial grasses. __________
The characterization of each biome is as follows:
Biomes that are characterized by long, cold winters and are adapted to the short summer growing season: Temperate deciduous forests. Biome that has uniformly warm and humid conditions, the nutrients that are released by decomposers allow for quick uptake by producers: tropical forests. Biome that has the annual precipitation is quite high rain falls only during certain times of the year. Grasses and widely scattered clumps of trees are the predominant vegetation: Savannah.Biome that has a drought-resistant perennial and much of this land is devoted to farming, with annual crops such as corn and wheat replacing the natural perennial grasses: Temperate grasslands. What is Biome?A biome may be defined as a very large ecosystem that is running in nature in an unmanaged way. In a more simple sense, a biome is characterized as a very large area that is significantly characterized by a particular type of vegetation. Some examples of biomes are tropical rainforests, coral reefs, grasslands, etc.
Temperate deciduous forests have an average rainfall of 75 to 200 cm/year and a temperature of 12 degrees Celcius. Tropical rainforests feel higher rainfall and temperature ranging from 25 to 29 degrees Celcius.
Therefore, the characterization of each rainfall is well described above.
