B cells can divide to form plasma cells. Each plasma cell contains many mitochondria
and an extensive endoplasmic reticulum. Referring to the function of plasma cells in your answer, explain why these features are important adaptations.
Answer:
Explanation:
The presence of mitochondria and an extensive endoplasmic reticulum are the features that are important for adaptations of the plasma cell because plasma cells (white blood cells) secrete immune proteins also called antibodies which only formed due to the presence of endoplasmic reticulum whose function is to formed proteins for the cell so that's why plasma cells have large sized endoplasmic reticulum.
Why would cells from the same organism have different functions?
Answer:
Explanation: Cells have to fulfill multiple different functions to be able to build complex multicellular organisms. Differently expressed genes lead to different proteins made in the cell, which leads to different morphology, shape or function. ... When this factor cannot be expressed, these cells do not develop at all.

they increase in size.
Answer:
The increase in size and changes in shape of a developing organism depend on the increase in the number and size of cells that make up the individual. Increase in cell number occurs by a precise cellular reproductive mechanism called mitosis.

Which answer choice accurately depicts the sequence by which blood moves from the pulmonary vein to the body tissues?
Answer:
See the answer below
Explanation:
Oxygen-rich blood flows from the lung through the pulmonary vein to the left atrium of the heart. From there, the blood is pumped through the mitral valve to the left ventricle. The contraction of the left side of the heart sends the oxygenated blood out of the left ventricle through the aortic arch to the major arteries designated to carry blood to the major parts of the body. From the arteries, blood moves to the capillaries and then to the various tissues of the body before returning back to the heart through the vein.
Thus, the sequence of flow of blood from the pulmonary vein to the body tissues can be summarized as:
Pulmonary vein -> Left atrium -> Arteries -> Capillaries -> tissues
Construct Explanations Based on evidence from your model, explain how hotspot volcanoes change Earth's surface. When there are tectonic plates
Answer:
High heat and lower pressure at the base of the lithosphere (tectonic plate) facilitates melting of the rock. This melt, called magma, rises through cracks and erupts to form volcanoes. As the tectonic plate moves over the stationary hot spot, the volcanoes are rafted away and new ones form in their place.

B. breaking the glucose into 2,3 carbon molecule D. breaking the glucose molecule to produce acetyl CoA
9. The enzymatic redox reaction process in Krebs Cycle produces what molecule?
A. Cytochrome oxidase C. Oxaloacetate
B. Succinate Acetate D. Oxaloxide
10. During electron transport chain, energy from the electrons of NADH and FADH2 is used in the process
chemiosmosis to __________.
A. reduce NADH to NAD+ C. phosphorylate ADP to ATP
B. reduce FADH2 to FAD D. pump hydrogen ions across the membrane
Answer:
7. D. breaking the glucose molecule to produce acetyl CoA
8. C. Oxaloacetate
10. phosphorylate ADP to ATP
Explanation:
Cellular respiration is the metabolic process by which energy in form of ATP is obtained in a cell. However, it occurs in three major stages namely: glycolysis, Krebs cycle and electron transport chain (oxidative phosphorylation).
- Glycolysis is the process where glucose is broken down to produce pyruvate, which is then processed into acetyl coA before it enters the next stage (Krebs cycle).
- Krebs cycle is the stage where series of REDOX reactions occur to produce OXALOACETIC ACID as a final product, which accepts acetyl coA for another cycle to begin.
- Electron transport chain (ETC) uses the energy derived from the electron carriers energy NADH and FADH2 to phosphorylate ADP to ATP in a process called CHEMIOSMOSIS.
Mitosis vs Meiosis, someone help me with this, ill give brainiest.
♡ hi there!! i tried to go back to my notes, but i couldn't find anything. but here if an explanation i found. ♡
different: mitosis consists of one stage whereas meiosis consists of two stages. mitosis produces diploid cells (46 chromosomes) whereas meiosis produces haploid cells (23 chromosomes). mitosis produces two identical daughter cells whereas meiosis produces four genetically different daughter cells.
similar: both involve cell division, both the processes occur in the M-phase of the cell cycle. In both cycles, the stages are common – metaphase, anaphase, telophase and prophase. synthesis of DNA occurs in both.
♡ i hope that helps!! good luck on your assignment or whatever thing you're working on! btw i love your pfp, chizuru mizuhara! ♡

can anyone explain me the Transpiration Pull in plants?
Answer:
As the water is lost from the leaf surface by transpiration, more water molecules are pulled up due to the tendency of water molecules to remain joined (cohesion), and thus to produce a continuous column of water through the stem is called transpiration pull.

if epigenetic changes take place above the level of the genome , what would be an example of a change at the level of the genome ?
Answer:
epigenetics chamges take place.
Epigenetics is the examination of the way cells manipulate gene interest without converting the DNA series." Epi-"approach on or above in Greek, and "epigenetic" describes elements past the genetic code.
Epigenetic changes are adjustments to DNA that modify whether or not genes are grown to become on or off. These adjustments are connected to DNA and do now no longer alternate the series of DNA constructing blocks. Within the entire set of DNA in a (genome), all the adjustments that modify the interest (expression) of the genes are referred to as the epigenome.
Because epigenetic changes assist decide whether or not genes are grown to become on or off, they affect the manufacturing of proteins in cells. This law facilitates making sure that everyone produces the handiest proteins which might be essential for its function. For example, proteins that sell bone boom aren't produced in muscle cells.
What is the epigenetic pattern?Patterns of epigenetic change range amongst individuals, in one-of-a-kind tissues inside an individual, or even in one-of-a-kind cells inside a tissue. Environmental influences, together with a person’s food plan and publicity to pollutants, can affect the epigenome. Epigenetic adjustments may be maintained from cell to as cells divide and, in a few cases.
Hence concluded that Epigenetics changes and causes cancers, by changing the genome, epigenome, or both.

How do living organisms return carbon to the atmosphere in the carbon cycle
Answer:
Carbon enters the atmosphere as carbon dioxide from respiration and combustion. Carbon dioxide is absorbed by producers to make glucose in photosynthesis
Living organisms return carbon to the atmosphere in the carbon cycle by two process namely respiration and combustion. Carbon dioxide is absorbed by producers to make glucose in photosynthesis.
What is photosynthesis?
A photosynthesis is a biochemical process which occurs in plants, algae, and bacteria, when they are exposed to sunlight. During photosynthesis, water and carbon dioxide join to form sugars and give off oxygen.
Respiration is defined as the inhaling of oxygen and the exhaling of carbon dioxide and combustion is defined as the process in which a substance burns in the presence of Oxygen, produce off heat and light in the process.

what would the chromosome to the right be called?
Answer:
The two identical chromosomes that result from DNA replication are referred to as sister chromatids. Sister chromatids are held together by proteins at a region of the chromosome called the centromere. Chromosomes undergo additional compaction at the beginning of mitosis.
Explanation:
Based on the position of centromere and length of chromosomal arms, the chromosomes are classified into 4 groups:
(1). Telocentric chromosomes.
(2). Acrocentric chromosomes.
(3). Sub-metacentric chromosomes.
(4). Metacentric chromosomes.
