D lytic infection
Answer:
D) lytic infection
Explanation:
During lytic infection, a virus enters the host cell, makes a copy of itself, and causes the cell to burst, or lyse.
Answer:
its D
Explanation:
lytic infection is the correct answer because the host cell will lyse AKA burst.
What step in photosynthesis may occur during day and night? A.Light independant reactions B.Light dependant reactions c. Photolysis
Answer:
a is the answer
Explanation:
Light independent reactions of photosynthesis may occur during day and night.
STAGES OF PHOTOSYNTHESIS:
Photosynthesis is a metabolic reaction undergone by green plants to obtain their food using energy from sunlight. Photosynthesis is a process that involves two major stages: light independent reactions and light reactions. Light dependent reactions occur strictly under light conditions because light is needed to break down water molecules in a process called photolysis. In the light dependent reactions, water is broken down by light to give oxygen gas. In the light independent reactions, carbon dioxide is required.However, light independent reactions may occur during day and night. This is because light independent reactions does not require light to occur.

How have freshwater and salt water fish adapted to deal with osmosis in their respective environments?
Answer:
Salt water fish are perfectly adapted to their salty environment and need osmosis to live. The replacement fluid taken on to replace the lost water is desalinated by a process known as diffusion. Diffusion allows fish to live in a state of constant osmosis

Why does sexual reproduction process create offspring with genetic variation (different genes between parents and siblings)?
Answer:
Sexual reproduction process creates offspring with genetic variation because their are 2 parents unlike in asexual reproduction where there's only 1 parent. Since, there are 2 parents with difference in their DNA & genes the offspring too will have a variation.

1. Which layer is the oldest? Which layer is the youngest? How do you know?
2. What are some characteristics of the organisms in layers 1-6?
3. What are some characteristics of the organisms in layers 7-12?
4. Develop a theory as to how the organisms in this area changed over time.
Answer:
the youngest layer is 7(middle point) because decomposition must occur in the middle of decomposed materials.the oldest is 12(upper one) because decomposed material are found at the top most of organisms.they are highly decomposed material.they don't decompose easilyThe youngest layer is 7(middle point) because decomposition must occur in the middle of decomposed materials. The oldest is 12(upper one) because decomposed material are found at the top most of organisms. They are highly decomposed material. They don't decompose easily.
What is Decomposition?Decomposition of organic matter is a complex process that involves the breakdown of complex molecules into simpler ones by the action of microorganisms. In the case of the layers mentioned, the higher layers are the oldest because the decomposed material is found at the top of the layer, and it takes a long time for the organic matter to decompose into soil.
The highly decomposed material in these layers is called humus. Humus is a dark brown or black organic substance that is a result of the decomposition of plant and animal matter. It is an essential component of healthy soil as it provides nutrients to plants and helps retain moisture in the soil.
Humus does not decompose easily because it is a stable form of organic matter. It is made up of complex molecules that are resistant to further decomposition. This makes it an important component of soil fertility as it can remain in the soil for hundreds of years, providing a steady source of nutrients for plants.
Overall, the highly decomposed material found in these layers is an important indicator of the age and health of the soil. Understanding the decomposition process and the factors that affect it can help us better manage our soil resources for agriculture, forestry, and other uses.

What is the repeating monomer of a DNA molecule?
triglyceride
O dipeptide
nucleotide
phospholipid
Answer:
3. Nucleotide
Explanation:
The repeating monomer of a DNA molecule is basically called as nucleotide. The correct option is C.
A nucleotide is the DNA molecule's repeating monomer. The building blocks of DNA are called nucleotides.
They are made up of three primary elements: a nitrogenous base (such as adenine, thymine, cytosine, or guanine), a sugar molecule (deoxyribose), and a phosphate group.
Covalent interactions between these nucleotides allow them to join together to form a lengthy chain or strand of DNA. The genetic information is encoded in the nitrogenous nucleotide sequence throughout the DNA strand.
DNA is able to carry and transmit genetic information from one generation to the next due to the specific nucleotide configuration.
Instead of being repeating monomers of DNA, triglycerides, dipeptides, and phospholipids are parts of other macromolecules.
Thus, the correct option is C.

Where do most volcanoes form?
A. Near plate boundaries
B. In the middle of tectonic plates
C. Where there is no plate movement
D. On a supercontinent
Explanation:
Most volcanoes form at the boundaries of Earth's tectonic plates. These plates are huge slabs of the Earth's crust and upper mantle, which fit together like pieces of a puzzle. These plates are not fixed, but are constantly moving at a very slow rate. ... Sometimes, the plates collide with one another or move apart.

When an action potential is generated within a motor neuron, ________. When an action potential is generated within a motor neuron, ________. all of the muscle cells within the motor unit are stimulated to relax the muscle cells from a neighboring motor unit will contract every muscle cell of the motor unit is stimulated to contract only select muscle cells within the motor unit are stimulated to contract the muscle cells of the motor unit will occasionally contract
Answer:
every muscle cell of the motor unit is stimulated to contract.
Explanation:
Stimulus in biology can be defined as an obvious change in either the chemical or physical structure of an organism' environment (either external or internal). Thus, all living organisms (both animals and plants) respond to changes in their environment and consequently, an appropriate response or reaction is made. Also, stimulus arising from within the organism is known as internal stimulus while those from its environment are known as the external stimulus.
In organisms, the specialized cells that detect stimulus are generally known as sensory receptors while a group of these receptors is referred to as sense organ. Therefore, the senses are necessary for behavior because stimuli must be sensed in order to respond.
Stimulus control can be defined as a phenomenon that arises when a living organism responds or behaves in the presence of a stimulus and in another way in the absence of a stimulus.
For example, opening the door of a microwave oven as soon as its timer beeps.
Example II; When your body touches a hot object, you quickly move away and feel some pain subsequently.
Action potentials generates the nerve impulse in a motor neuron.
When an action potential is generated within a motor neuron, every muscle cell of the motor unit is stimulated to contract.

If the DNA molecule is only composed of four possible nitrogen bases, how can thousands of different proteins be formed from such a limited set of fixed shapes?
Answer:
nucleotides are only building blocks whose combinations determine different codons which subsequently associate in a sequential manner in order to create different amino acid combinations
Explanation:
A gene is a specific segment of DNA whose (nucleotide) sequence is copied into an RNA during the process of transcription, typically a messenger RNA (mRNA) molecule which is subsequently used to synthesize a protein. During translation, each triplet of nucleotides, i.e., each codon, corresponds to a specific amino acid. There are 64 possible codons (4³: 64), which can combine in different ways to create different amino acid combinations, and thus they are responsible for the generation of a huge amount of proteins coded by a given genome.
