Carbon has an atomic number of 6. Which of the following does the atomic number 6 tell you about carbon?
Answer:
The atomic number only tells you how many protons an element has, regardless of the amount of neutrons etc.
Carbon 6 therefore has 6 protons, and that's the only thing you can deduce from its atomic number.

Which of the following is not a function of a vertebrate’s endoskeleton?
a.) Increase speed of digestion
b.) Protect major organs
c.) Offer support and structure
d.) Connect with muscles to create movement
Increase speed of digestion is not a function of a vertebrate’s endoskeleton. So, the correct option is (A).
What is Endoskeleton?
The rigid part which provides internal support of the structure is called endoskeleton which develops from endoderm and is called a living structure. Some examples of endoskeleton are cartilage, bone etc. The hard part that is on the outside of the body that protects the soft tissues and muscles is called the exoskeleton.
Vertebrates are animals that have a backbone and an endoskeleton which is a skeleton inside their body while invertebrates are animals that do not have a backbone. Invertebrates may have a skeleton on the outside of their body called an exoskeleton, while some invertebrates have no skeleton at all.
It protects major organs, offer support to the structure, connect the muscles to create movement.
Thus, Increase speed of digestion is not a function of a vertebrate’s endoskeleton. So, the correct option is (A).

jill made the table below during her research on aquatic zones and living organisms. Based on jills observations, which conclusion can you draw? (ik the answer i just need the explanation)
Answer:
B. There are no producers in the benthic zone that relay on photosynthesis.
Explanation:
There are no producers present in the benthic zone because benthic zone is located in higher depth where there is no sunlight so no photosynthesis occurs there. We know that photosynthesis only occurs in the presence of sunlight, if there is no sunlight then there is no photosynthesis occurs and as a result no producer can survive there so we can conclude that there is no producers present in the benthic zone .
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.
How does the release of carbon dioxide by microorganisms benefit plant life?
a.
It reduces the acidity of water in soil, which increases water absorption and provides plants with necessary water.
b.
It increases the acidity of water in soil leading to the breakdown of rocks in soil. This releases nutrients which can be used by plants.
c.
It decreases the acidity of water in soil leading to the breakdown of rocks in soil. This releases nutrients which an be used by plants.
d.
It increases the acidity of water in soil, which decreases water absorption providing plant life with firmer soil for root growth.
Answer:
b.
It increases the acidity of water in soil leading to the breakdown of rocks in soil. This releases nutrients which can be used by plants.
Explanation:
When microorganisms release carbon dioxide into the soil, the acidity of water surrounding soil particles is increased. This increase in acidity allows for rock present in soil to be broken down, releasing minerals into the soil. These minerals are then available for use by plant life.

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.

Environmental impact has also been seen through human activity with agriculture. This is due to the high amounts of monoculture farming. Although having large agricultural fields of one crop can be efficient, it results in attracting a higher number of pests, which, in turn, results in a high use of pesticides. Identify a solution that would possibly remedy this issue and explain why that action would be beneficial.
Explanation:
Pesticides, fertilizers and other toxic farm chemicals can poison fresh water, marine ecosystems, air and soil. They also can remain in the environment for generations. Many pesticides are suspected of disrupting the hormonal systems of people and wildlife. Fertilizer run-off impacts waterways and coral reefs.
