The diagram shows two cells. Identify structures C, D, and E and explain how they work together to perform a specific process within the cell.
Structure C, D, and E in the diagram represent the endoplasmic reticulum, the ribosome, and the Golgi apparatus respectively.
When the ribosomes are attached to the endoplasmic reticulum, they give it a rough appearance.
The ribosome, endoplasmic reticulum, and the Golgi apparatus work together in the synthesis and transport of protein within the cell. In other words, they are all involved in the secretory pathway of cells.
The ribosome represents the actual site of protein synthesis.The endoplasmic reticulum gets involved by folding the synthesized proteins and packaging them into secretory vesicles. Thereafter, the vesicles are transported to the Golgi apparatus.The packaged proteins undergo further processing within the Golgi apparatus before they are exported to the cell membrane via the cytosol.In other words, the 3 organelles work together to form the secretory pathway of the cell. They are involved in the synthesis, packaging, processing, and eventual transport of proteins to their target sites.

Certain traits, such as color blindness, are determined by an X-linked recessive gene. A couple in which both have normal vision have a color-blind son. The probability of this couple having a daughter who is a carrier is
Answer:
A daughter can become a carrier in one of two ways – she can acquire the ‘gene’ from a carrier mother or from a color blind father.
Explanation:
If a woman has only one color blind ‘gene’ she is known as a ‘carrier’ but she won’t be color blind. When she has a child she will give one of her X chromosomes to the child. If she gives the X chromosome with the color blindness ‘gene’ to her son he will be color blind, but if he receives the X chromosome which doesn’t carry the color blindness ‘gene’, he won’t be color blind.
A color blind boy can’t receive a color blind ‘gene’ from his father, even if his father is color blind, because his father can only pass an X chromosome to his daughters.
A color blind daughter therefore must have a father who is color blind and a mother who is a carrier (who has also passed the color blindness ‘gene’ to her daughter). If her father is not color blind, a ‘carrier’ daughter won’t be color blind. A daughter can become a carrier in one of two ways – she can acquire the ‘gene’ from a carrier mother or from a color blind father.

Even though they have several differences, a bacterium and a human cell will both contain DNA. With respect to evolution, what does this fact suggest?
Answer:
the fact that they both contain DNA in the nucleus of their cells, this suggests that they had a common ancestor they evolved from.

What are the features of DNA?Deoxyribonucleic acid is a polymer composed of two polynucleotide chains that coil around each other to form a double helix. The polymer carries genetic instructions for the development, functioning, growth and reproduction.
DNA is a complex, long-chained molecule that contains the genetic blueprint for building and maintaining all living organisms. Found in nearly all cells, DNA carries the instructions needed to create proteins, specific molecules essential to the development and functioning of the body.
DNA contains the instructions needed for an organism to develop, survive and reproduce. To carry out these functions, DNA sequences must be converted into messages that can be used to produce proteins.

Forest A consists of only Oak trees and Forest B has Oak trees, Maple trees, and some pine trees. Which of the following is true?
Question 3 options:
Forest B has more biodiversity than Forest A.
Forest A has more biodiversity than Forest B.
Forest B, which has more tree species, is more biodiversity compared to Forest A that has just one tree species. The true statement is: "Forest B has more biodiversity than Forest A."
Biodiversity can simply be described as the variation that exist within an ecosystem whereby different organisms and species can be found in a particular habitat. The more varied the species that exist in an ecosystem are, the higher the biodiversity that exists.
Like the saying goes: "variety is the spice of life". The higher the biodiversity the better. Which means the more varied the species or organisms found in an habitat or ecosystem, the more functional the ecosystem would be.
In Forest A, only one tree species, which is Oak trees exist compared to Forest B that has different tree species.
Therefore, Forest B will have more biodiversity than Forest A.

What is a blood clot?, Pliz l will mark you the brainest
Answer:
a blood clot is a gelatinous mass of fibrin and blood cells formed by the coagulation of blood
Explanation:
Answer:
Blood ClotThe process of forming a clot or thrombus in order to prevent excess loss of blood from the body is called the clotting of blood. A jelly mass like substance is formed by the platelets and fibrin in the blood. Platelets play a vital role in the clotting of blood.
Given below is the flow chart representing the major steps involved in the process of clotting of blood:
Injury to blood vessel and platelets release prothrombin
⇓
Activation of prothrombin to thrombin
⇓
Splitting up of fibrinogen to fibrins by thrombin
⇓
A mesh is formed around the wound controlling RBC and platelets by fibers present in fibrins
⇓
Bleeding is stopped
⇓
The clot hardens and becomes smaller in size
⇓
New cells are grown to rebuild the wounded site
⇓
Plasmin enzymes are released and the clot is dissolved
