CUCKOO AND WARBLER symbiotic relationship?
Answer:
The relationship between the Cuckoo Bird and the Warbler is a parasitic symbiotic relationship.
Explanation:
The Warbler lays their eggs in the Cuckoo bird's nests that their offspring can be cared for by the other bird. The Warbler benefits by not having to care for their young while the Cuckoo bird is harmed by having to care for the extra birds in their nests.
How does the oxygen from inhalation get transferred to the cells of the body?
a. It moves from the bronchioles to the lymphatic system which moves it throughout the body.

c. It is absorbed from the lungs by the organs that need it.
d. It moves from the bronchi to the heart to then get pumped throughout the body.
Answer:
the answer of this question is option B

Please and don’t waste my time bu saying that you don’t know the answer. thank you :) I hope you have a nice day
Answer:
Plants exchange oxygen and carbon dioxide. The oxygen is used for respiration and is also a waste product of photsynthesis. The carbon dioxide is used for photsynthesis.
During the day time, the stomata of the plant will open to let the carbon dioxide in for photsynthesis. Cabron dioxide diffuses into the leaf down a concetration gradient. oxygen will leave the leaf down the concentration gradient.
This process is the gas exchnage of plants.
How stomata open: Stomata open during the dayby absorbing water vapor, become turgid and and open. During the night, the stomata becomes flaccid and floppy. this causes it to close.
Explanation:
plants use water, carbon dioxide, and sunlight to make oxygen, water, and what other product

A(n) _____ is a thick film of protein secreted by mucous membranes in the mouth that coats teeth and provides a substrate for Stretptococcus mutans to adhere and begin the formation of a slime layer.
Answer:
The correct answer is - the biofilm.
Explanation:
Biofilms are a type of one or more than one type of microbes that grow on many different surfaces, These microbes include fungi, bacteria, and protist that develop attached to the surface and one another and embedded in a self-produced matrix.
It is a thick film of protein such as fibrin, polysaccharides such as alginate or eDNA secreted by the bacteria, and other microbes that cover the teeth surface.

Scientists recently studied the reproductive behavior of a yeast species. They noticed a new species emerged from two populations. This new species formed after the yeast were exposed to signaling molecules called pheromones. Both male and females release pheromones, which bind to cell surface receptors. Pheromones from the male bind to female cells. The opposite is true for pheromones secreted from female cells. This signaling action causes the yeast to change their sex type.
Explain how this phenotypic plasticity is beneficial.
Answer:
Phenotypic plasticity in yeast cells is beneficial because this allows the yeast to change its phenotype of being a male or female. This plasticity depends on the type of pheromone exposure. The ability to change phenotype increases the reproductive success of yeast cells. This condition is useful for yeast, especially if they must adapt to changes affecting their reproduction and survival. By having phenotypic plasticity, the yeast can continue to grow its population size.
Answer:
When the yeast is exposed to a pheromone, its phenotypic plasticity allows it to change its sex type, meaning if there is a yeast molecule that is releasing pheromones close to another molecule of yeast, the latter molecule will change its sex type to the opposite sex, if necessary, to reproduce. The yeast's phenotypic plasticity regarding sex type allows it to grow the population more effectively, helping the species survive.
Sedimentary rocks are not found on the Moon because
A. there is no silicon on the Moon.
B. lava flows are missing from the surface.
C. the Moon's gravity is too weak.
D. there is no weathering on the Moon.
Answer:
D, There is no Weathering on the moon
Explanation:
The moon doesn't have an atmosphere therefore there cannot be any Sedimentary rocks on the Moon.

Sebaceous glands in the skin produce oil that lubricates the skin and hair shafts. What organelle are cells in the sebaceous gland likely to have a lot of so that they can produce all of this oil
Answer:
The sebaceous glands are responsible for forming sebum
Explanation:
The fat glands are formed by acini and excretory ducts that are the bait formers.
These acini have a highly developed REG in their interior since they have a high protein coding, this is the reason that the acinar cells have a good basophilic color in H&E sections in MO.
Which disappears more rapidly from a population, a deleterious dominant allele or a deleterious recessive allele?
Answer:
Selection is a directional process that leads to an increase or a decrease in the frequency of genes or genotypes. Selection is the process that increases the frequencies of plant resistance alleles in natural ecosystems through coevolution, and it is the process that increases the frequencies of virulence alleles in agricultural ecosystems during boom and bust cycles.
Selection occurs in response to a specific environmental factor. It is a central topic of population and evolutionary biology. The consequence of natural selection on the genetic structure and evolution of organisms is complicated. Natural selection can decrease the genetic variation in populations of organisms by selecting for or against a specific gene or gene combination (leading to directional selection). It can increase the genetic variation in populations by selecting for or against several genes or gene combinations (leading to disruptive selection or balancing selection). Natural selection might lead to speciation through the accumulation of adaptive genetic differences among reproductively isolated populations. Selection can also prevent speciation by homogenizing the population genetic structure across all locations.
Selection in plant pathology is mainly considered in the framework of gene-for-gene coevolution. Plant pathologists often think in terms of Van der Plank and his concept of "stabilizing selection" that would operate against pathogen strains with unnecessary virulence. As we will see shortly, Van der Plank used the wrong term, as he was actually referring to directional selection against unneeded virulence alleles.
A deleterious dominant allele would disappear more slowly from a population compared to a deleterious recessive allele.
What is a deleterious dominant allele?In the case of a deleterious dominant allele, the individual possessing the allele will always express the negative trait associated with it, making it easier to identify and potentially select against. In contrast, a deleterious recessive allele may not be expressed in individuals who carry only one copy of the allele, as the normal copy of the gene can still produce enough functional protein to mask the effects of the deleterious allele.
As a result, the deleterious recessive allele can persist in a population as carriers pass the allele on to their offspring without showing any negative effects themselves. However, over time, the recessive allele may become more common in the population, increasing the likelihood of two carriers mating and producing offspring that express the deleterious trait.

How many different genotypes and phenotypes will there be in the F2 generation?
Answer:
in the offspring. F2 showed 4 different phenotypes: the round and yellow traits did not stay linked to each other. Ratios for each trait corresponds to what one would expect from monohybrid crosses. Shuffling of traits occurs before they realign in every possible combination.
