Define negative feedback in biology

Answers

Answer 1

Answer:

A negative feedback loop occurs in biology when the product of a reaction leads to a decrease in that reaction. In this way, a negative feedback loop brings a system closer to a target of stability or homeostasis

Explanation:

Negative feedback occurs when some function of the output of a system, process, or mechanism is fed back in a manner that tends to reduce the fluctuations in the output, whether caused by changes in the input or by other disturbances

In a forest community, a shelf fungus and a slug live on the side of a decaying tree trunk. The fungus digests and absorbs materials from the tree, while the slug eats algae growing on the outside of the trunk. These organisms do not compete with one another because they occupy

A. the same habitat, but different niches
B. the same niche, but different habitats
C. the same niche and the same habitat
D. different habitats and different niches

Answers

Answer: A because they live in the same habitat but they both have different roles that do not compete with each other

The shelf fungus and slug in the forest community do not compete with each other as they have the same habitat, but different niches. Thus, option A is correct.

What are habitat and niche?

Habitat is defined as the place where the species resides while the niche is the role of the specific organisms or the species in that particular habitat or environment. The niche includes the impact of the species on the habitat.

The shelf fungus and the slug both live on the side of the tree and hence have the same habitat but the fungus takes minerals from the tree and the slug from the algae making them differ in the niche.

Therefore, the fungus and slug have the same habitat but different niches.

What is Respiratory System?

The respiratory system is the network of organs and tissues which helps with breathing that includes the airways, lungs, and blood vessels. The muscles that power the lungs are also part of the respiratory system. They work together to move oxygen throughout the body and to clean up waste gases like carbon dioxide.

Respiratory system consists of following parts like

Nose--> Mouth--> Pharynx --> Larynx --> Trachea --> Bronchi --> Bronchioles --> Alveoli

The respiratory system has many functions others than inhaling (breathe in) and exhaling (breathe out), it:

It allows talking and smelling.It warms the air to match the body temperature and moisturizes it to the moisture level the body needs.It transports oxygen to the cells in your body.It removes waste gases, including carbon dioxide, from the body when you exhale.It protects the airways from harmful substances and irritants

Thus, following are the parts of Respiratory system:

1.Nose

Select all that apply.
exocytosis
phagocytosis
diffusion
pinocytosis

Answers

Answer:

Exocytosis, phagocytosis, and pinocytosis

Explanation:

Active transport is when energy is used to move substances across the cellular membrane.

Exocytosis requires energy to remove materials from the cell; it is active.

Phagocytosis also requires energy; it is active.

Diffusion isn't active because it moves materials down their concentration gradient and therefore it doesn't require energy.

Pinocytosis is a form of endocytosis and requires energy; it is active.

Answers

Answer:

F1 Generation

Explanation:

In the study of genetics the offspring of the P generation is referred to as the F1 generation.

In the study of genetics, the offspring of the P generation are referred to as the F1 offspring, or first fillial offspring. Their genetic makeup depends on their parents.

What is inheritance?

Inheritance explains how the genes from the parents pass down to the offspring. An example is when both parents are tall because they are purebred, then all the F1 offspring are tall.

The T is represented by tall, and the t is represented by short. TT is purebred tall, and tt is purebred short. When two parents (P generation) are heterozygous for tallness, such as Tt, each will produce gametes such as T and t. From these gametes, three types of individuals are formed, such as purebred tall (TT), heterozygous tall (Tt), and purebred short (tt). These are called F1 offspring.

Hence,  in the study of genetics, the offspring of the P generation are referred to as the F1 offspring, or first fillial offspring.

2: 1. Body cells make up the body of any multicellular organism. On the other hand, a gamete is a sex cell that can either be a sperm or egg cell.

2. Body cells undergo the process of mitosis while gametes undergo a process called meiosis.

3. A body cell contains a complete number of chromosomes and is called a diploid cell while a gamete contains only half the number of chromosomes of its parent cell, and it is called a haploid cell.

3. Identical twins

4. nucleotide triplets

5. A gene is a sequence of nucleotide bases that specifies certain products; RNA or proteins. It is the segment of DNA that holds the information to build and maintain an organism's cell and also pass genetic traits to offspring. Hence, it is the molecular unit of heredity in living organisms.

The DNA is a long double-helical structure that stores the genetic information in our cells. It consists of two long polynucleotide chains composed of the four nucleotides subunits (A, C, G, T).

In order for the long strand of DNA to fit into the cell's nucleus, it is coiled around certain proteins called HISTONES to form Chromatin, which undergoes further coiling and organization to to linear CHROMOSOMES.

The chromosomes are structured within the nucleus, that are made up of the cell's genetic material (DNA). In eukaryotic cells, the nucleus houses the cell's DNA and directs protein synthesis (expression of the information encoded by genes).
