Why is it important for an area to have high biodiversity
Answer:
Biodiversity boosts ecosystem productivity where each species, no matter how small, all have an important role to play. ... A larger number of plant species means a greater variety of crops. Greater species diversity ensures natural sustainability for all life forms.
Explanation:
What leads to the changes in shape of the active site when pH changes?
A. more H+ interfere with the amino acid bonds
B. the OH- ions break apart the amino acids
Answer:
A. more H+ interfere with the amino acid bonds
Explanation:
Enzymes are also sensitive to pH. Changing the pH of its surroundings will also change the shape of the active site of an enzyme.
This contributes to the folding of the enzyme molecule, its shape, and the shape of the active site. Changing the pH will affect the charges on the amino acid molecules.
Answer: A. more H+ interfere with the amino acid bonds

Natural selection results in ______. increased genetic variation increased genetic variation , a population that is better adapted to a future environment a population that is better adapted to a future environment , an increase in the size of a population an increase in the size of a population , a population that is adapted to its current environment a population that is adapted to its current environment Skip to navigation
Answer:
a population that is adapted to its current environment.
Explanation:
The theory of natural selection explains the development of adaptive features by organisms required to survive in their current environment. The theory supports the survival of the fittest idea whereby those organisms with the most equipped environmentally adaptive features survive. Theae features are also passed from parents to offspring on a bid to facilitate their adaptation to their current environment. This means different organisms develop features required for each of their present environment.
What substances does the excretory system get rid of?
Answer:
This is the job of the excretory system. You remove waste as a gas (carbon dioxide), as a liquid (urine and sweat), and as a solid. Excretion is the process of removing wastes and excess water from the body. Recall that carbon dioxide travels through the blood and is transferred to the lungs where it is exhaled

Can someone help me if this is correct
Answer:
I think your answer is wrong. The right answer is D. Nucleus & Ribosome.
Explanation:
A process that takes place in the cells of all living things: the production of proteins. This process is called protein synthesis, and it actually consists of two processes — transcription and translation. During translation, the genetic code in mRNA is read and used to make a protein. These two processes are summed up by the central dogma of molecular biology: DNA → RNA → Protein. In eukaryotic cells, transcription takes place in the nucleus. During transcription, DNA is used as a template to make a molecule of messenger RNA (mRNA). The molecule of mRNA then leaves the nucleus and goes to a ribosome in the cytoplasm, where translation occurs.
The nucleus contains the cell's DNA and directs the synthesis of ribosomes and proteins. Typically, the nucleus is the most prominent organelle in a cell. Eukaryotic cells have a true nucleus, which means the cell’s DNA is surrounded by a membrane. Therefore, the nucleus houses the cell’s DNA and directs the synthesis of proteins and ribosomes, the cellular organelles responsible for protein synthesis.

Are scans done with MRI, CAT scan, PET scan, X-ray, or ultrasound machines?
Answer:
MRI: Magnetic resonance imaging (MRI) uses the body's natural magnetic properties to produce detailed images from any part of the body.
CAT/CT scan: is an upgraded version of an X-ray, which it uses multiple x-rays taken from different angles all around a body. Then uses a computer to create complex cross-sectional images of parts of a body
PET scan: uses radioactive tracers dyes which put into a body(by being swallowed, injecting, etc.). Which is tracked by the PET scanner, creating an image. PET helps to visualize the biochemical changes taking place in the body, such as the metabolism (the process by which cells change food into energy after food is digested and absorbed into the blood) of the heart muscle.
X-ray: when a negatively charged electrode is heated by electricity and electrons are released. Which produces energy that is directed toward an anode at high velocity. Producing an X-ray when the energy collides with the atoms in the metal plate.
Ultrasound: using a small transducer it both transmits sound waves into the body and records the waves that echo back.
Explanation:
Answer:
I cannot figure out what it is you would like to know. Please think about how your question is worded, and make it clear. In usual medical terminology, static x-rays produce images but are not considered scans, whereas all the others are ‘scans’. CT uses X-rays to make a ‘scanned’ image of internal soft tissues that do not show well on simple static X-ray imaging. MRI uses magnetism and radio ‘waves’, ultrasound uses a version of echolocation, PET uses a radioactive ‘tracer’ compound.

PLEASE ANSWER THE QUESTION BELOW
Answer:
Explanation:
A diagram of a Punnett Square showing the chromosomes involved in the inheritance of sex-linked traits.
The female had the genotype XHXh, and produced the two gametes seen at the left side of the diagram.
The male had the genotype XHY0, and produced the two gametes seen at the right side of the diagram.
The genotypes seen in the center of the square represent the possible genotypes of the F1 generation.
Two female offspring are produced for every two male offspring.
One male and one female offspring inherit normal genes.
One female is heterozygous for the hemophilia trait and is considered a carrier.
One male receives a damaged X-chromosome and inherits the condition known as hemophilia.
The student is studying the movement of substances across the cell membrane. She understands that some substances combine with special transport proteins to be carried across the cell membrane. The substances can move only from an area of higher concentration to one of lower concentration. This process is known as:
Answer:
Facilitated diffusion
Explanation:
Facilitated diffusion is the transport of hydrophilic molecules that can not freely cross the membrane. Channel protein and many carrier proteins are in charge of this transport. When uncharged molecules cross the membrane, they do it according to their concentration gradients, going from the more concentrated side to the lower concentrated one. When ions need to cross the membrane, the process depends on an electrochemical gradient.
Facilitated diffusion is a passive transport process because they only depend on electrochemical gradients, so they do not need any energy to occur.

how does energy get into the air also what happens to the air temperature
Answer:
Since air is a poor conductor, most energy transfer by conduction occurs right near Earth's surface. Conduction directly affects air temperature only a few centimeters into the atmosphere. During the day, sunlight heats the ground, which in turn heats the air directly above it via conduction.

How is cytokinesis different
in plants and animals
Answer:
MAIN DIFFERENCES
- During cytokinesis, animal cells undergo a narrowing in the center, which does not occur in plant cells.
- Once the process is finished, the plant cells are partially united while in the case of animals they remain separated.
- A fundamental difference is that in animals, cytogenesis occurs by strangulation, but this is not the case of plants, which is by septation.
