The rising levels of oxytocin during childbirth contractions are an example of what type of feedback?
A. positive
B. negative
C. neither
Answer:
A. Positive
Explanation:
The release of oxytocin from the posterior pituitary gland during labor is an example of positive feedback mechanism. Oxytocin stimulates the muscle contractions that push the baby through the birth canal. The release of oxytocin result in stronger or augmented contractions during labor.
A positive feedback is an increase, while a negative feedback is a decrease.

Most plants appear green because chlorophyll:
A. absorbs green light
B. absorbs voilet light
C. reflects green light
D. does not absorb voilet light
C. reflects green light
Chlorophyll gives plants their green color because it does not absorb the green wavelengths of white light. That particular light wavelength is reflected from the plant, so it appears green.
so its option C.

The pedigree below shows the inheritance of a dominant allele of a gene in a family over several generation. Circles represent females and squares represent males. Shaded symbols indicate individuals carrying the allele. The pedigree suggest that the gene is on a nuclear chromosome, and not on a mitochondrial DNA, because A) mitochondrial genes are not heritable B) mitochondrial mutations cannot produce dominant traits C) maternal mitochondrial mutations are inherited by all of a mother's offspring D) mitochondrial DNA is circular, whereas chromosomal DNA is linear
Complete question:
You will find the pedigree in the attached files
Answer:
The correct option is C) maternal mitochondrial mutations are inherited by all of a mother's offspring.
Explanation:
Mitochondrial inheritance is one of the ways in which a disease or a trait might be inherited from the maternal line.
Most of the DNI is located in the nucleus, but there is also DNI in mitochondria. Sperm cells hardly carry mitochondria, so mitochondrial DNI is mostly inherited from the maternal side. If there exists any mutation in this DNI, the whole progeny of the mutated woman will be affected, as they will get the mother´s mitochondria carrying the mutation. On the contrary, if there is a man affected by a disease caused by a mutation in mitochondrial DNI, non of their descendants will get the disease.
In the exposed pedigree, we can see that the mother is affected by the disease, but the couple had two daughters, and only one of them was affected, while the other one was not. This tells us that the mutation occurred on a nuclear chromosome. If the mutated allele was in mitochondria, both daughters would be affected.
The pedigree suggests that the gene is on a nuclear chromosome, and not on a mitochondrial DNA because maternal mitochondrial mutations are inherited by all of a mother's offspring (Option C).
Mitochondrial DNA (mtDNA) is a special type of genetic material that exhibits a matrilineal inheritance pattern.In consequence, all genes (and mutations) contained in mtDNA will pass from the mother to her offspring.It is for that reason that mtDNA is widely used in evolutionary studies (we can trace matrilineal lineage from mtDNA).In conclusion, the pedigree suggests that the gene is on a nuclear chromosome, and not on a mitochondrial DNA because maternal mitochondrial mutations are inherited by all of a mother's offspring (Option C).

Brendan made a chart to categorize the characteristics of animals.
An empty 2-column table titled Characteristics of Animals. Column 1 is labeled Always. Column 2 is labeled Sometimes.
Which phrase should be written in the column titled "Sometimes”?
Are multicellular
Have membrane-bound organelles
Produce their own food
Display an asymmetrical body plan
Answer:
Im gonna say produce their own food, i may or may not be wrong. sorry
Explanation:
Animals are multicellular and have membrane-bound organelles, sometimes display an asymmetrical body plan and sometimes they produce their own food. Thus, the correct option are C and D.
What is an asymmetrical body plan?Animals are the organisms which are multicellular eukaryotic organisms. Animals have all membrane-bound organelles such as mitochondria, chloroplast, etc.
Animals sometimes produce their own food. Animals also are asymmetrical sometimes because they have disproportionate arrangement of body parts, which exhibits no pattern. However, animals are also symmetrical sometimes because of the proportional arrangement of body parts and pattern.
Therefore, the correct option are C and D.

When humans come to a previously pristine environment, they inadvertently bring organisms with them that can be harmful to the local flora and fauna. Such organisms are known as _____.
Answer:
INVASIVE species
Explanation:
In biology, an organism is said to be INVASIVE if the organism is foreign to a particular region or habitat and possess the unpleasant ability to proliferate or grow rapidly to the point of competing with local species of organisms.
According to this question, humans are said to introduce organisms that have the ability to harm the local flora and fauna. Hence, these organisms are INVASIVE SPECIES because they are foreign to that place and cause damage in their new environment.

QUICK ASAP PLS Certain bacteria live and grow on the roots of some plants and produce chemicals that are beneficial to the plants. Which of the following observations best supports the claim that this relationship is beneficial to the plants?
Group of answer choices
Plants with a higher amount of the bacteria on their roots have increased rates of survival and reproduction.
When the bacteria are removed from the plant roots and are grown in a laboratory setting, they fail to survive.
The population size of the bacteria varies greatly depending on the chemistry of the soil and the type of the plant.
The chemical produced by the bacteria can be created by humans and added to the soil where it reaches the roots of the plant.
Answer:
Explanation: Plants with a higher amount of the bacteria on their roots have increased rates of survival and reproduction.

Why is investment in capital goods important for a country like Japan? Japan's economy depends heavily on industry and must be modern to be competitive. Japan needs investment in capital goods to develop its rich natural resources. Investment in capital goods makes up for a poor literacy rate in Japan. Investment in capital goods makes overseas trade unnecessary.
Answer: Japan's economy depends heavily on industry and must be modern to be competitive.
Explanation:
Capital goods are referred to as the physical assets which are utilized during production process and they're simply used to produce other goods. Examples of capital goods are machinery, buildings, vehicles etc.
Investment in capital goods is important for a country like Japan because the economy of Japan depends heavily on industry and must be modern to be competitive. It is a highly industrialized country and must continually invest in order to keep up with other nations.

describe the different processes involved in the movement of these substances into and out of the cell; oxygen, carbon dioxide, glucose, potassium, water, and enzymes.
Answer:
Dissolved or gaseous substances have to pass through the cell membrane to get into or out of a cell. Diffusion is one of the processes that allows this to happen. Diffusion occurs when particles spread.
Explanation:
To enter or exit a cell, dissolved or gaseous substances must pass through the cell membrane. One of the mechanisms that makes this possible is diffusion. Particles diffuse when they spread.
What is cell?Cell is defined as the fundamental membrane-bound entity that houses the essential molecules of life and is the building block of all living things.
It can also be defined as a semipermeable cell membrane encloses one or more nuclei, cytoplasm, and different organelles, which are the smallest structural component of an organism capable of autonomous functioning.
There are basically two types of cell.
Prokaryotic cellEukaryotic cellCell membrane is defined as a biological membrane that keeps all cells' interiors isolated from the outer world and provides protection for it.\
Barriers and gatekeepers are cell membranes. Because of their semi-permeability, some molecules can diffuse across the lipid bilayer but not others.
Thus, to enter or exit a cell, dissolved or gaseous substances must pass through the cell membrane. One of the mechanisms that makes this possible is diffusion. Particles diffuse when they spread.
