proteins by rough endoplasmic reticulum and modification of
newly synthesized HIV-membrane proteins is done by Golgi
apparatus.
B)All cell organelles including ribosomes, Rough and smooth
endoplasmic reticulum and vesicles are used to synthesize one type
of viral protein.
C) Only ribosomes are used by the virus for protein synthesis.

Which of the following statements about phenotypes and genotypes is false?
A. Phenotype can be changed by the environment.
B. Genotype affects phenotype by providing the instructions for making proteins.
C. Phenotype is an organism's visible characteristics.
D. An organism's phenotype is only made up of genes and alleles.
Answer:
D. An organism's phenotype is only made up of genes and alleles.
An organism's phenotype is only made up of genes and alleles is the false statement about genotype and phenotype.Therefore, the correct option is D.
What is a genotype and phenotype?Genotype refers to the genetic makeup of an organism, including all of its inherited genes and variations. Phenotype refers to the physical characteristics and traits of an organism that result from both its genetic makeup (genotype) and environmental factors.
The given statement is false because an organism's phenotype is not only determined by its genes and alleles, but also by environmental factors such as diet, exposure to sunlight, and other external factors.Therefore, the correct option is D.

What are several reasons why apoptosis happens
Answer:
There are several reasons: it gets rid of cells that are not needed, in the way or potentially dangerous to the rest of the organism. "Cells that are not needed may never have had a function. In other cases, they may have lost their function, or they may have competed and lost out to other cells.
Explanation:
Explain why John converted change in mass to percentage change in mass.
Answer:
Explanation:
The difference in mass does not deal with the proportional aspect of the solutions, making the results less accurate. The percent was calculated to give an exact difference, along with considering the quantities of solution.

The heart rate increases during exercise. This increase in heart rate increases blood flow to the muscles. Explain, as fully as you can, why this increase in heart rate is necessary.
pls help I am on a timer, think it is biology but not sure
Answer:
Getting your heart beating faster than it's resting rate each day trains your body to move oxygen and blood to your muscles more efficiently. This helps your muscles use that fuel more economically as well, and ultimately you move with more ease. In other words, you end up in shape.

In one student's family, two of the children have curly hair, one child has wavy hair, and the fourth child has straight hair.
Which of these processes is responsible for the variety of hair texture in this family?
Answer:
A. sexual reproduction
Explanation:
The inheritance of multiple phenotype genes that is the mother will have heterozygous as well as the father will have the heterozygous condition as well. The process is included in genetics and the genetics is related to it.
What is genetics ?It is defined as the study of genes and study of genes expression along with all the genetic factors associated with it.
The expression of the hair that is expressed in the progeny of the parents where the multiple expression is present can show incomplete dominance as well where none of the phenotype that is the alleles and the genes that are present in the parents will not express it in the child.
The process is also called as recombination where both the traits re expressed in the child and the characters both associated with the parents will express in the child.

Describe how the process of apoptosis occurs?
Answer:
Apoptosis is an orderly process in which the cell's contents break down and are packaged into small packets of membrane for “garbage collection” by immune cells. It contrasts with necrosis (death by injury), in which the dying cell's contents spill out and cause inflammation. Apoptosis removes cells during development.
Apoptosis is a form of programmed cell death that occurs in multicellular organisms.
What is apoptosis ?It is a natural biological process of programmed cell death in which the cells destroy themselves and maintain the smooth function of the body parts.
There are two types cell death such as Programmed death of cells or apoptosis and uncontrolled death or Necrosis.
Apoptosis can occur via two pathway such as Extrinsic Pathway is triggered in response to external stimuli, ligand binding at death receptor and these receptors are called as Tumor Necrosis Factor gene.
Intrinsic Pathway triggered in response to internal stimuli such as biochemical stress, DNA damage and this pathway is modulated Bax, and Bcl-2 molecules.
Apoptosis helps in maintaining homeostasis, proper size of the body, cell number, elimination of unwanted cell, T-lymphocytes etc.

List 4 concepts you learned in this unit about waves and explain how each one applies to your life (4 points)
Answer:
amplitude, wavelength, frequency, and speed.
Explanation: Sound is a type of wave that moves through matter and then vibrates our eardrums so we can hear. Light is a special kind of wave that is made up of photons. You can drop a rock into a pond and see waves form in the water. We even use waves (microwaves) to cook our food really fast. Water waves are the focus of our Tsunamis and surf resources, but many other kinds of wave exist. These include sound waves, light waves, radio waves, microwaves and others. All kinds of waves have the same fundamental properties of reflection, refraction, diffraction and interference, and all waves have a wavelength, frequency, speed and amplitude.

Where does the mRNA go after it is produced?
Answer:
The mRNA goes after it is produced is made messenger RNA (mRNA) is a single-stranded RNA molecule that is complementary to one of the DNA strands of a gene. The mRNA is an RNA version of the gene that leaves the cell nucleus and moves to the cytoplasm where proteins are made.
Explanation:
mRNA formed in the nucleus is transported out of the nucleus and into the cytoplasm where it attaches to the ribosomes. Proteins are assembled on the ribosomes using the mRNA nucleotide sequence as a guide. Thus mRNA carries a “message” from the nucleus to the cytoplasm.

What additional restriction enzyme would be used to cut out another gene flanked by a different restriction site?
Answer:
a clone
Explanation:
Restriction enzymes are DNA-cutting enzymes. Each enzyme recognizes one or a few target sequences and cuts DNA at or near those sequences. Many restriction enzymes make staggered cuts, producing ends with single-stranded DNA overhangs. However, some produce blunt ends.
What are some of the WORST things about coal fuel?
help me please help me
Answer:
Explanation:
The burning of fossil fuels releases greenhouse gases into the atmosphere, increasing levels of CO2 and other gasses, trapping heat, and contributing to global climate change. Coal combustion releases the greenhouse gases carbon dioxide (CO2) and nitrous oxide (N2O) during combustion. The major disadvantage of coal is its negative impact on the environment. Coal-burning energy plants are a major source of air pollution and greenhouse gas emissions. In addition to carbon monoxide and heavy metals like mercury, the use of coal releases sulfur dioxide, a harmful substance linked to acid rain.
Answer:
Air pollution
Can impact health of citizens like asthma, breathing difficulties, etc.
Can lead to death if not treated or fixed.
Releases greenhouse gases into the atmosphere.
