The picture is showing the biological classification patriarchy where the first is the kingdom that is the first level and the last one is species.
What is binomial nomenclature ?It is the naming of the organism in which the scientific name is written into two parts as genus and the other one is species.
The answer to this question will be a, f, b, e, d and c, The order is always the kingdom> order> family> genus > species and two classification system is given by It is the cycle in which the first one is the kingdom that is the one to which a specimen belongs.
In the taxonomy hierarchy, the organisms are divided and classified as. Taxonomy is the branch of biology that studies about the name and the nomenclature of the species. Lineus gave the first system of classification. Genus is defined as the species group that are having the same characters.

Variation in genotype is caused by
O None of the above
e phenotypes changing more quickly than genotypes.
o recombination of genes as a result of sexual reproduction.
O
O mutations only.
Answer:
Mutations, the changes in the sequences of genes in DNA, are one source of genetic variation. Another source is gene flow, or the movement of genes between different groups of organisms. Finally, genetic variation can be a result of sexual reproduction, which leads to the creation of new combinations of genes.

B.
Should unborn children be tested in the womb for genetic disorders?
C.
Should scientists be permitted to genetically modify plants?
D.

Answer:
D. all of these.
Explanation:
All of these are the questions that involves ethical considerations because the method used in these questions are not doing naturally. Vitro fertilization is the fusion of woman's egg with the sperm of male outside the uterus of women which is unethical. Testing of unborn children in the womb for genetic disorders and producing genetically modify plants are also unethical because it does not occur naturally.

Speculate how mutations cause changes that can then be seen over many generations.
Answer:
Over thousands of generations, many mutations will be introduced into a population and some of these will increase to a detectable frequency as a result of selection or genetic drift. Both of these processes may take a long time to make a measurable increase in allele diversity. hope this helps :D
Mutations are errors produced during DNA replication. These errors can be perpetuated by successive cell divisions in daughter mutated cells.
A mutation is any alteration in the genetic material (DNA) of an organism. These mutations can occur as spontaneous genetic errors during DNA replication.
In somatic and germinal cells which suffered a mutation, each successive DNA replication cycle before mitosis/meiosis will produce new daughter cells carrying the mutation.
The consequence of this process is the perpetuation of the mutation in the cell lineage originated from a parental 'mutated' cell.
The DNA repair mechanisms work to avoid the perpetuation of genetic mutations.
Somatic mutations cannot be passed to the next generation (i.e., they are inherited by somatic cells that divide through mitosis), whereas germline mutations can eventually be inherited in the next generations through gametes.
In conclusion, mutations are errors produced during DNA replication. These errors can be perpetuated by successive cell divisions in daughter mutated cells. In germline cells, mutations can eventually be inherited by successive generations.

After fertilization, the successful development of a mature, full-term fetus depends on A. The release of human chorionic gonadotropin (hCG) by the developing placenta AND the production of estrogen and progesterone by the placental tissues B. the release of human chorionic gonadotropin (hCG) by the developing placenta C. maintenance of the corpus luteum for all 9 months D. all of these E. the production of estrogen and progesterone by the placental tissues
Answer:
The correct option is A (The release of human chorionic gonadotropin (hCG) by the developing placenta AND the production of estrogen and progesterone by the placental tissues).
Explanation:
The developing placenta release Human chorionic gonadotropin (hCG) during pregnancy. What this hormone does is tell the body (corpus luteum) to produce progesterone to maintain the pregnancy. The presence of Human chorionic gonadotropin is a sign of pregnancy, meaning successful fertilization had happened, and implantation of the embryo had occurred too, preventing another cycle of menstruation.
The successful development of a mature, full-term fetus also depends on estrogen which during pregnancy aids the formation of blood vessels and also aids fetal maturation. While progesterone is a hormone when released during pregnancy helps maintain a healthy pregnancy.

Flowering Locus C (FLC) is a gene that is responsible for flowering in certain plants. FLC is expressed in new seedlings, which prevents flowering. Upon exposure to cold temperatures, FLC expression decreases and the plant flowers. FLC is regulated through epigenetic modifications. What type of epigenetic modifications are present in new seedlings and after cold exposure
Answer:
- New seedlings: histone acetylation
- After cold exposure: histone methylation
Explanation:
Vernalization is an adaptive mechanism whose objective is to ensure that flowering occurs only after winter (i.e., after cold conditions). In certain plants, this process (vernalization) suppresses the expression of genes that encode repressors of flowering. In Arabidopsis, vernalization is associated with histone modifications at FLC chromatin. The FLOWERING LOCUS C (FLC) is a MADS-box gene that acts as a repressor of flowering in Arabidopsis. Epigenetic modifications control the expression of the FLC gene. The FLC gene is expressed at low temperatures due to histone acetylation at FLC chromatin, and thereby the expression of FLC mRNA transcripts ensures that the Arabidopsis plant cannot flower. Subsequently, as the Arabidopsis plant is exposed to cold, FLC is repressed by the accumulation of trimethylation on lysine 27 of histone 3 (H3K27me3), thereby allowing it to flower when temperatures become warmer.

Answer:
When an animal breathes, it takes in oxygen gas and releases carbon dioxide gas into the atmosphere. This carbon dioxide is a waste product produced by the animal's cells during cellular respiration. Cellular respiration occurs in the individual cells. Digested foods have chemical energy stored in them.

Choices: bronchi, nasal cavity, capillaries, trachea, pharynx, aveoli, bronchioles
Answer:
Nasal Cavity, Pharynx, Trachea, Bronchi, Bronchioles, Alveoli and Capillaries.
Explanation:
We first breathe in the air through our nose so it goes through our nasal cavity. After that it goes down our throat past the pharynx (voice box) and through the trachea (windpipe). From here it arrives in our lungs via the bronchi, which then splits into smaller bronchioles which have alveoli at the end of them. The alveoli then have small capillaries which the oxygen goes into so it can travel around the body through the bloodstream.
