Based on the similarities, what defines an ecosystem?
Answer:
An ecosystem consists of a community of organisms together with their physical environment. In ecosystems, both matter and energy are conserved. Energy flows through the system usually from light to heat while matter is recycled.
Explanation:
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.
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.

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.

Which of the following is an example of a heritable characteristic (or inheritable trait) possessed by an animal that will improve its reproductive potential and survivability in its environment?
a. Position of geese flying in V formation
b. Color and shape camouflage of praying mantis
c. Muscle atrophy in aging dogs
d. Male dominance in a pack of wolves
The color and shape camouflage of praying mantises is an example of an heritable trait possessed by an animal that will improve its reproductive ability and survivability in its environment. So, the correct option is (B).
What are Traits?A phenotypic trait is defined as a specific type of a phenotypic characteristic of an organism that can be either inherited or environmentally determined, but usually occurs as a combination of both.
These are characteristics or features of an organism that are expressed by genes and/or influenced by the environment including physical properties of the organism such as hair color, leaf shape, size, etc., and behavioral characteristics such as bird nests.
The color and shape camouflage of praying mantises is an example of an heritable trait. Thus, the correct option is (B).

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.
