Answer:
The foot
Explanation:
Mollusks have bilateral symmetry and are coelomed protostomes, but the coelom is only represented by small residual spaces around the pericardial cavity, the gonads, some parts of the nephridia, and in some cases part of the intestine. The foot is used primarily as a means of movement. The foot is also a very important structure, although it has adapted differently depending on the classes of mollusks. It is characterized by having a really powerful and complex musculature. The most widespread use of this organ is that of locomotion, as happens with gastropods. However, in bivalves it serves to burrow or in cephalopods it helps to provide propulsion.
Invertebrate animals with the unsegmented soft body which is enclosed in shells made up of calcium carbonate are called Mollusca.
The part of mollusk's specialized in feeding, burrowing and movement are:
Foot
The Mollusca can be explained as:
The Mollusca have the bilateral type of symmetry and coelomate protostomes which are visible as residual spaces surrounding the pericardial cavity, nephridia and gonads.The foot is the part that is used in locomotion and is adapted differently for various purposes in various forms of Mollusca.It has a complex musculature and helps in propulsion, as a mode of feeding appendage and in some for burrowing purposes.Therefore, the foot is a specialized organ.

How do small food molecules such as glucose get from ur gut to the cells
Answer:
The cells along the small intestine use primary active transport to ensure that glucose only flows one way: from digested food to the inside of cells. Active transport proteins use adenosine triphosphate (ATP), the cell’s energy storage molecule, to pump glucose into the cell, either with or against the concentration gradient.

a scientist is studying a population of fungi. she finds that the recessive allele for small spores has a frequency of 0.75. what frequency should she expect for the dominant allele?
If the scientist finds the frequency for recessive alleles to be 0.75, then she could expect the frequency for the dominant allele to be 0.25.
According to Hardy Weinberg equilibrium principle, the genetic variations like genotypes and frequencies of the alleles would remain constant from one generation to another in the absence of disturbing external factors. These disturbing factors can be mutations, selective mating, natural selection, gene flow and genetic drift. All of these factors disturb the equilibrium by introducing external alleles, thus suppressing the ability of an organism to carry its own alleles to the next generation.
In the absence of the disturbing factors, the allele frequencies (taken as p and q) are always constant, and would be equal to 1. This means that:
p + q = 1
Where p denotes recessive allele frequency while q denotes dominant allele frequency. If p = 0.75, then q would be:
q = 1 - 0.75 = 0.25.

Dna sequences in many human genes are very similar to the sequences of corresponding genes in chimpanzees. The most likely explanation for this result is that.
The most likely explanation for this result is that humans and chimpanzees share a relatively recent common ancestor.
Scientific research has shown that about 98.8% of the human genome matches with a chimpanzee genome. The occurrence of such similarities between genomes of two organisms predicts that both the organisms had a common ancestor in the near past.
The DNA studies of an organism help to determine how closely or distinctively related two species of organisms are. Organisms with a similar genome are considered to be having a common ancestor in the near past. As humans and chimpanzees have a vast similarity index between their genomes, this explains that both these organisms evolved from a common ancestor in the near past.
These evolutionary relationships help scientists to study how a particular organism evolved into the form that can be seen today.

Fermentation is a chemical reaction that takes place in the cytoplasm and occurs when oxygen is Choose... . Byproducts of fermentation may include Choose... or Choose... . Fermentation yields Choose... ATP than the electron transport chain.
Answer:
Fermentation is a chemical reaction that takes place in the cytoplasm and occurs when oxygen is low or absent. Byproducts of fermentation may include lactic acid or ethanol. Fermentation yields less ATP than the electron transport chain.
Explanation:
Fermentation is a chemical reaction that occurs under anaerobic or low-oxygen condition whereby the NADH produced during glycolysis is oxidized to NAD⁺ with the production of lactic acid as well as other products such as ethanol.
Since oxygen is lacking, pyruvate and NADH produced in glycolysis cannot be oxidized. In order to produce energy in the form of ATP for the cells and tissues,the NAD⁺ is regenerated from NADH by the reduction of pyruvate to lactic acid by the enzyme lactate dehydrogenase. In some other organisms such as yeast and microorganisms, pyruvate is converted to ethanol and carbon dioxide.
The net production of ATP in fermentation process is 2 molecules of ATp much lesser than that produced in aerobic respiration.

Study this unusual food chain. What could ‘P’ represent?
a. Any normal insect that eats grains.
b. An insect that can make its own food.
c. A carnivorous plant like the Venus flytrap.
d. There is a mistake - nothing can match 'P'.
The correct option as to what P could represent in the food chain would be option C.
P could be a carnivorous plant such as Venus flytrap because these plants are able to get their food both by harnessing solar energy to photosynthesize and by feeding on flying insects.
On the other hand, P cannot be any normal insect that eats grains or makes its own food because according to the diagram, P also derives energy from the sun. Only plants and some microbes are able to photosynthesize.
Therefore, only a carnivorous plant is able to both photosynthesize and feed on insects for their foods when necessary and hence, can fill the space of P in the food chain.

3. Many pea plants have rounded pods, but some have flat pods because they are homozygous for a recessive
allele (d). A plant that is homozygous for the dominant allele and another plant that has flat pods are crossed. Two of
the offspring are then taken and they are crossed to produce more offspring (called F2 offspring). There are 200 F2
offspring plants. Predict the number that will have flat pods. Show all your working.
The proportion of offspring homozygous recessive for at least two of the three traits is 6 out of 16 total offspring. Then it becomes 3/8.
The genotype of each plant contributes to its phenotype. In this case, the phenotype is the appearance of that flower. A given genotype is said to be homozygous if it has two identical alleles, and heterozygous if the two alleles are different. The process of genotyping is called genotyping.
Wood Since there are offspring that are homozygous recessive for both traits, each parent must have at least one recessive allele for each trait. Thus, the white disc parent has the WwDd genotype, and the white sphere parent has the Wwdd genotype. A cross between a long-stemmed pea and a short-stemmed pea is an example of a monohybrid cross. Crossing the two produces heterozygous offspring.

There will be 50 offsprings that will have flat pods.
As shown in the image below,
F2 offspring are total 4 in number with 3round pod plants and 1 flat pod plant.
As given in the question there are 200 F2 offspring,
So, number of flat pods will be =( 1/4) x 200
=50
In monohybrid cross, both the alleles ( R and r) are expressed in the F2 generation without any blending. Thus, the law of segregation is based on the fact that each gamete contain only one allele.
here,A monohybrid cross results in a phenotypic ratio of 3:1 (dominant to recessive), and a genotypic ratio of 1:2:1 (homozygous dominant to heterozygous to homozygous recessive).

rainforest use oxygen for?
Answer:
Animals and plants use oxygen for processing cellular respiration.
Explanation:
Most of all organisms use oxygen to undergo cellular respiration with the help of the mitochondria that powers energy. Cellular respiration is needed to obtain energy for survival. As products of cellular respiration, ATP energy is created, and carbon dioxide + water is released from the organism. Thus, an ecosystem like a rainforest with animals and plants use oxygen for processing cellular respiration.

What are the advantages of differential staining procedures over the simple staining technique.
Answer:
The advantages of differential staining procedures over the simple staining technique are:
Explanation:
Different species of bacteria may be identified from one another by having different stains applied to them because of differential staining. Various stains used on bacteria will highlight their unique characteristics since different cells don't really stain in exactly the same manner. A gram stain is an illustration of a differential stain. A stain known as crystal violet is used in gram staining, which makes cells purple and may be used to separate gram-positive and gram-negative cell walls because it can be removed from the cell walls of gram-negative but remains on the gram-positive cell walls. While one cationic dye is applied by a simple stain, giving the clear cells some color so we can see it properly. But it's not always possible to distinguish various kinds of organisms. We can only notice their presence.
