Answer:A
Explanation:
Organisms are classify on the basis of kingdoms Bacteria, Protista, Fungi, Plantae, Animalia, Phylum. Therefore, option (A) is correct.
How do we classify organisms?Organisms can be classified according to any number of criteria, including overall similarities, colors, ecological functions, etc. However, it is generally agreed that the most useful way for scientists to organize biological diversity is to group organisms according to shared evolutionary history.
It is divided into phyla or divisions, which are further subdivided into classes. Further divisions include order, family, genus and species, in that order. Thus, species is the basic unit of classification.
Organisms are usually grouped together based on their unique characteristics. The classification of an organism often provides useful information about its evolutionary history and which other organisms are related to it.

A student is presented with a model of a digestive system and is asked to remove one structure (small or large organ) that will have the largest impact on decreasing chemical digestion. Which structure should the student remove
Answer:
Small intestine
Explanation:
Digestion is the process of breaking down food molecules into simpler and usable forms by the body cells. The process of digestion involved the mechanical aspect and chemical aspect. The mechanical one deals with using physical means like chewing to break down the food particles.
However, the chemical one deals with the usage of chemically-secreted enzymes to work on the food molecules. Lots of digestive organs are involved in this chemical digestion, but, the most of chemical digestion takes place in the SMALL INTESTINE. The small intestine is where most of the chemical digestion occurs including absorption.
Hence, according to this question, the student should remove the SMALL INTESTINE because it will have the largest impact on decreasing chemical digestion.

Some genes are important enough to be called "molecular switch" or "master" genes. What is the purpose of these genes?
A. They control when other genes are expressed
B. They determine the organization of the genome
C. They regulate cell metabolism
D. They modulate the rate of translation
Answer:
Genes called "molecular switch" or master genes have the purpose of control when other genes are expressed (option A).
Explanation:
Master gene is so named because it has the function of controlling the behavior of other genes, organizing their functions and regulating when they can be expressed.
The name of molecular switch is synonymous with the master gene, since its activation determines the genetic regulation necessary to establish cell differentiation and even the determination of the sex of some species.
The other options are not correct because:
B. Master genes do not determine the organization of the genome .
C. Regulation of cell metabolism depends of substances as hormones and enzymes.
D. The rate of translation does not depend on the activity of master genes.

Which process is identified by number 1 in the diagram and where in the cell does this process occur?
DNA
mRNA
Protein
1
2
O replication; during the cell cycle
O transcription; in the nucleus of the cell
translation; at the ribosome
transcription; at the ribosome
The process is identified by number 1 in the diagram and where in the cell does this process occur is translation, at the ribosome. Thus option 3 is correct.
What is translation?Translation is defined as the process by which a messenger RNA (mRNA) molecule's sequence is converted into an amino acid sequence during protein synthesis.
It is also be defined as when DNA is converted to RNA in the cell's nucleus, the process through which ribosomes in the cytoplasm or endoplasmic reticulum synthesize proteins. Gene expression refers to the entire process.
Initiation, elongation, and termination are the three phases of an mRNA molecule's translation by the ribosome.
Thus, the process is identified by number 1 in the diagram and where in the cell does this process occur is translation, at the ribosome. Thus option 3 is correct.

In silkworms,yellow cocoon (B) is dominat over white cocoon(b). If the mom is BB and the dad is bb, what are the chances they have offspring with yellow cocoons?
Answer:
100 %
Explanation:
Dominance is a genetic phenomenon where a gene variant or allele masks the effects of another allele (of the same gene) in heterozygous individuals. This last gene variant is referred to as the recessive allele. In this case, the silkworm mother can produce only one type of gamete carrying the dominant gene (B) form, while the silkworm father can produce only one type of gamete carrying the recessive gene (b) form. In consequence, from this cross, all offspring (100 %) will be heterozygous (Bb) and therefore they will express the dominant trait (i.e., yellow cocoon).

How could you make the lab better?
Answer:

Explanation:
Need help plz!!! Trying to catch up on biology anything can help!!!!
Answer:
See the answer below
Explanation:
The control group in an experimental study is the subject group that is not administered the treatment variable. The control group forms the baseline for comparing the effects produced by the treatment variable on the experimental group.
Thus, in this case, the control group would be the 10 mice that were not exposed to the radio waves.
The independent or the manipulated variable, in this case, is the exposure or otherwise of the mice to the radio waves.
The dependent variable is the actual variable that is going to be measured, otherwise known as the effect variable. In this case, the dependent variable would be the strength of the mice measured by their ability to push the block of wood blocking their food.
Since 8 out 10 mice and 7 out of 10 mice were able to push the wooden block in both the experimental and the control group, Bart's conclusion should reject the hypothesis that the radio waves make mice extra strong.
Bart's experiment can be improved by increasing the number of subject mice in each group. The more the number of subjects, the more the accuracy of the outcome would be.
In a plant species, the allele for dark green leaves (D) is dominant over the allele for light green leaves (d). A plant with Genotype (Dd) is crossed with a plant with genotype (did). What percentage of the offspring are expected to be hybrid for the leaf color trait. A 0% B 25%. C.50%. D 75%
The percentage of the offspring that is expected to be hybrid for the leaf color trait is 50%. The correct option is C.
What are alleles?The trait is caused by a pair of two alleles on the chromosome, and there are two possible outcomes. The dominant allele, which is typically written in capital letters and will control the organism's phenotype even in the presence of the other allele, is the one that has the ability to silence the other allele.
It is used in biology to refer to inherited traits that do not manifest in the phenotype of the individual who possesses them but may do so in their offspring.
Recessive alleles, which are only expressed when they are homozygous, are this other type of allele. Both heterozygous and homozygous genotypes exhibit the dominant allele.
Dd is crossed by dd.
100 / 2 = 50%.
Therefore, the correct option is C.
