How does a cell's external environment affect the movement of water across the cell membrane?
Answer:
water molecules move according to the energy from where they are to where they're going.
Explanation:
The external environment of the cell significantly affects the movement of water across the cell membrane when a cell is placed in three types of solution.
What is a cell membrane?A cell membrane may be defined as a type of biological membrane that significantly separates and protects the interior environment of all cells with respect to the outside environment. It is semi-permeable in nature which regulates the transport of materials entering and exiting the cell.
If a cell is placed in a hypertonic solution, water will migrate out of the cell, and the cell will shrink. In an isotonic environment, there is no net water movement, so there is no change in the size of the cell. When a cell is placed in a hypotonic environment, water will enter the cell, and the cell will swell.
Therefore, the external environment of the cell significantly affects the movement of water across the cell membrane when a cell is placed in three types of solution.

Which of the following processes occurs in the mitochondria?
cellular mutations
cellular respiration
transcription
translation
Answer:
Process that occurs in the mitochondria is cellular respiration (second option).
Explanation:
Cellular respiration consists of the process in which an energetic substrate, such as glucose, is oxidized for energy, in the presence of oxygen. This process occurs in a cellular organelle called the mitochondrion.
In the mitochondria, oxidative phosphorylation and the electron transport chain occur as part of energy production, processes that are linked to produce cellular respiration and obtain energy in the form of ATP.
The other options are not correct because:
Cellular mutations occur at the molecular level, in the DNA. Transcription occurs in the cell nucleus. Translation occurs in the cytoplasm, with the participation of mRNA and ribosomes.how does botany and stomach contents help during a crime scene investigation

3.4.4 Why are cells so small?
1. Write a brief summary of the main steps you took in the procedure. Be sure to describe any adjustments you made to the procedure and why you made them.
Cells are small because they can absorb nutrients much more efficiently. Because they are smaller they can efficiently absorb enough food. ... When a cell doubles in size the volume increases much more then the surface area, which is why large cells cannot receive enough food efficiently for their volume.

Ecosystem-based management represents a paradigm-shift in the way we manage natural resources in the U.S.
1. What are some potential roadblocks to EBM at the policy level?
2. At the constituent level?
3. How would you suggest a way forward?
Answer:
1. The need for an appropriate management unit, creation of administrative bodies and the poor knowledge of the ecosystem function and time constraints.
2. Limited resources to implement the projects with little existing knowledge of the system. It is vague in concept and ignores the historic and individual factors that might influence the ecosystem functionality.
3. There must be an established communication with the management and adaptive management should be adopted to counter the unpredictable nature of the ecosystem.
Explanation:
Ecosystem-based management is an environmental approach to analyze the interaction between species and their environment. It studies the terrestrial and marine species and environment and factors within these environments that cause behavioral change and migration.
During photosynthesis, specific pigments absorb light energy, which is then used to fuel the building of sugar molecules. Which colors correspond to the wavelengths of light that are strongly absorbed by each pigment
Answer:
Chlorophyll a- violet blue
Chlorophyll b - orange red
Carotenoids- green yellow
Explanation:
The three major plant pigments are chlorophyll a, chlorophyll b and carotenoids.
Various pigments are identified by their specific pattern of wavelength absorption in the spectrum of visible light. Chlorophyll a absorbs light in the violet-blue region, while chlorophyll b absorbs orange-red light. Chlorophyll a and b reflects or transmits green light hence they appear green. Carotenoids absorb light in the green - yellow region hence they reflect longer yellow, red, and orange light.

Fill in the following flowchart to show the pathway of a red blood cell as
journeys from the right ventricle to the brain.
lungs
right ventricle
left atrium
brain
What substance does haemoglobin in red blood cells form as the blood
through the lungs?
Answer:
1. The pathway of a red blood cell from the right ventricle to the brain is:
Right ventricle → pulmonary arteries → lungs → pulmonary veins → left atrium → left ventricle → artery aorta → arterial vessels → brain .
2. The substance that forms hemoglobin in red blood cells when it passes through the lungs is oxyhemoglobin.
Explanation:
Red blood cells are structures present in the blood, whose function is to transport oxygen (O₂) and carbon dioxide (CO₂). This process requires travel throughout the body, through the blood vessels, and gas exchange at the pulmonary and tissue level.
1. A red blood cell in the right ventricle contains carbon dioxide and must pass to the lungs to be oxygenated. The route it takes from there includes Right ventricle (minor circulation) → pulmonary arteries → lungs → pulmonary veins → left atrium → left ventricle → (joining the major circulation) artery aorta → arterial vessels → brain .
2. The red blood cell or erythrocyte contains a molecule, called hemoglobin, which has an iron core that allows it to bind to O₂ and CO₂ in order to transport them. The affinity for one molecule or another depends on the presence of a certain gas in a certain place.
When the red blood cell passes through the lungs, the concentration of O₂ is higher than CO₂, so the latter is released and O₂ binds to hemoglobin, a conjugation that is called oxyhemoglobin.

Choose true or false for each statement listed below.1. The most prevalent alleles in a population are called wild type alleles
Answer:
The statement is true.
Explanation:
The wild type allele or wild allele of a gene refers to the allele that predominates in the general population, that is, the most frequent allele that is arbitrarily designated as normal is often called the wild type allele (dominant but not always), these they are responsible for the wild type phenotype and are used as a standard to compare other mutations that occur at a particular locus. A mutant allele has modified genetic information often specifying an altered gene product.

When early embryo are releasing chemicals to nearby cells to elicit protein production in the activated neighboring cells. What is the primary function of the signaling molecule?
a. facilitating cell death
b. initiating gene translation
c. regulating gene expression
d. stimulating cell division
Answer:
c. regulating gene expression
Explanation:
During development, early embryo cells release different ligand molecules that bind to specific receptors on the surface of nearby cells, thereby triggering signaling pathways involved in cell differentiation and development. These signaling events have been associated with the activation of transcription factors located in the cytoplasm which are then translocated into the nucleus where they activate the transcription of target genes. For example, sonic hedgehog (SHH) is a peptide hormone that plays roles during animal development. SHH is secreted by epithelial cells to activate transcription factors in nearby cells involved in several developmental processes.

A type O woman marries a man with type B blood, given that both of their mothers were type O, predict their possible offspring.
Answer:
For a woman with type O blood and a man with type B blood, whose mother was of type O blood, the possible offspring will consist of B and O children.
Explanation:
Blood type is an inherited trait and is determined by the presence or absence of antigens A and B on the surface of the erythrocyte:
Blood type A contains the antigen A and its genotype can be A|A or A|O. Blood type B contains the antigen B, whose genotype may be B|B or B|O. Blood type AB contains both antigens and a single genotype expression A|B. Blood type O lacks surface antigens, with a unique O|O genotype.In the above case, the woman has an O blood type, whose genotype is O|O. The male must be heterozygous, since his mother was of blood type O, so his genotype is B|O.
♂ B|O ♀ O|OTo know the possible descendants of this couple, the crossing of the wolf alleles must be done:
Alleles B O
O B|O O|O
O B|O O|O
From where the probabilities of the offspring are obtained:
Individuals with blood type B and genotype B|O 50% Individuals with blood type O and genotype O|O 50%Therefore, from this crossing only descendants of individuals with blood type B and O can be obtained.

How to get BA/BE Services from reliable suppliers?
Bioavailability (BA) refers to the degree and rate at which the administered drug is absorbed by the circulatory system, thereby accessing the sites of action. BA is one of the essential tools in drug development, since it must be considered when calculating dosages for non-intravenous routes of administration based on absorption.
