Which of the following describes a positive feedback loop? O When blood sugar concentration is too low, the endocrine system secretes hormones that increase blood sugar concentration to a normal level.
O When the body senses that the heart rate is very high, it secretes hormones that decrease the heart rate.
O When blood sugar concentration is too high, the endocrine system secretes hormones that decrease blood sugar concentration to a normal level.
O When someone is exercising intensely, the body secretes hormones that increase oxygen supply for cellular respiration.

Answers

Answer 1

Answer:

The statement that describes a positivefeedback loop is as follows: when blood sugar concentration is too low, the endocrine system secretes hormones that increase bloodsugar concentration to a normal level.

What is positive feedback loop?

A positive feedback loop is a feedbackloop that occurs in nature when the product of a reaction leads to an increase in that reaction.

A negative feedbackloop, on the other hand, occurs when increased output from the system inhibits future production by the system.

Therefore, the statement that describes a positive feedback loop is as follows: when blood sugar concentration is too low, the endocrine system secretes hormones that increase blood sugarconcentration to a normal level.

In exocytosis, the membrane package fuses with _____. the nucleus
the cell membrane
a transport protein
a gap junction

Answers

Answer:

The correct answer is the plasma membrane.

Exocytosis is the process by which substances are excreted or exported out of the cell. These substances are exported with the help of membrane bound transport vesicles.

Cargo or substance needed to be exported are packaged into the transport vesicles with the help of Golgi apparatus.

These vesicles then flow towards the plasma membrane.

The membranes of the vesicles then fuse with the plasma membrane.

It provides the cargo the passage to move out of the cell .i.e. cargo is secreted out of the cell.

Answer: actully plasma membrane isnt evev one of the chocies it would be the cell membrane

Where in an embryo are the instructions located for how to build organs

Answers

All the instructions are encoded in the DNA within the nucleus. We don't fully understand how the zygote, with the same genetic material as our adult cells, instructs the newly developing embryo to form tissues and organs, but it is all in the DNA.

It's cell differentiation signals produced by nucleus of cells. In an embryo, there are unspecialized pluripotent embryonic stem cells that rely on cell signals to differentiate into organs, even before the embryo is formed, in the blastocyst stage, there are 2 layers of cells, the inner cell mass is destined to form internal organs, and the outer ball of cells forms skin cells, intestines etc

If two objects of the same size will always have the same mass?

Answers

This is incorrect. Size and mass are not related. An example, a balloon that is filled with air can be compared to a bunch of iron that is of the same size yet it has much a smaller mass than the lump of iron.

Which nutrients function as coenzymes and are needed in only small amounts?

Answers

Answer:

Vitamins

Explanation:

The organic molecules which are needed by the organisms in small amounts in order to maintain the proper functioning of the metabolic processes of organisms are known as vitamins.

There are various biochemical functions that the vitamins perform in the body of organisms. As for example some functions have been mentioned below -

Vitamin A regulated cell growth and tissue differentiation.
Vitamin D regulates the mineral metabolism for the bones.
Vitamin B complex functions as a coenzyme.
Vitamin C and E both function as the antioxidants in the body of organisms.

Minerals form from magma in predictable patterns in a process know as

Answers

Minerals form from magma in predictable patterns in a process known as Bowen's reaction series.

Bowen's reaction series is the general model for the formation and the crystallization sequence of magma as the cooling process occurs. Bowen's reaction series was the idea of Norman L. Bowen. The series explains that minerals crystallize differently at certain temperatures as they cool. It also states why specific types of minerals are found together and why others are almost never connected with one another.
