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.

What is the function of the organelle identified in the picture
Answer:
An organelle is a subcellular structure that has one or more specific jobs to perform in the cell, much like an organ does in the body. Among the more important cell organelles are the nuclei, which store genetic information; mitochondria, which produce chemical energy; and ribosomes, which assemble proteins.

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.

1. What is the function of a top predator in an ecosystem?
A. It increases the food for other predator species.
B. It creates imbalance in the ecosystem.
C. It maintains populations. **
D. It helps increase the number of prey.
Reason - The answer is C because predators couldn't possibly increase the food for other predators. They obviously don't imbalance the ecosystem since they help keep it cycling. And they can't increase the number of prey if they're eating prey so therfore you're left with C.
2. Which is considered a top predator in the ocean?
A. A shark**
B. A sea lion
C. A small whale
D. A bird.
Reason - The answer is A because actually the top predator in the ocean is the killer whale but since it's not an option, you'd wanna go for a shark. A small whale obviously couldn't eat a big shark, nor could any of the others. :)
3. What happens to an ecosystem during normal seasonal flooding?
A. The biodiversity of the area reaches equilibrium.
B. The biodiversity of the area increases. **
C. The biodiversity of the area decreases.
D. The biodiversity of the area stays the same.
Reason - Just trust, I'm trying to finish this post and got tired of giving reasons. Sorry and thanks:)
4. How is the impact of seasonal flooding different from damming a river?
A. Seasonal flooding helps balance biodiversity, but damming does not.
B. Seasonal flooding is not considered an ecological disturbance like damming.
C. Seasonal flooding does not impact biodiversity for as long term as damming.**
D. Seasonal flooding increases biodiversity, but damming does not.
Reason - Again, trying to finish this and tired of typing reasons but the answer is indeed C because damming a river can causes long-term damage to biodiversity and the ecosystem while it can quickly recover from a flood because it doesn't really damage as much and the flood will simply be gone after a bit. :)
5. Would a long-term increase in the average temperature of a region be considered a significant disturbance in the ecosystem?
A. No, because it would not create large-scale changes in the environment.
B. No, because increases and decreases in average temperatures are normal.
C. Yes, because such a change could have a large-scale impact on wildlife. **
D. Yes, because any slight change in temperature is considered a distribution.
Reason - Eh.. it's pretty self explanatory.
It maintains the population. The top predator of the ocean is a shark, biodiversity of the area increases, the seasonal flooding may impact biodiversity for as long term as damming. Yes, due to the change could have a large-scale impact on wildlife.
What are the Exkplanion for the above answers?As per the top predators of the ecosystem, thy duty is to maintain the level of populating in the community. As they hunt down prey and thus be balanced. The ocean is just like the land is full of predators and prey the shark is the largest top predators species in the oceans.
A dammed river can create long-term damage to the biodiversity of the region. As flooding can lead to disaster and may impact the food supply. A long-term increase in the temperature of the region can lead to a large impact on wildlife.

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.

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.

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.
