DNA is a type of _______ that contains the genetic instructions of an organism's development and functioning.A.
lipid
B.
nucleic acid
C.
carbohydrate
D.
protein

Answers

Answer 1

Answer:

Answer:

The correct answer is B. nucleic acid

Explanation:

DNA (deoxyribonucleic acid) is a biomolecule which belongs to the chemical groups of nucleic acids. Nucleic acids include DNA and RNA (ribonucleic acid) and they were called in this way because they were discovered initially within the nucleus of the cells. They are polymers- composed by nucleotids bonded in definited sequences- and they are in charge of the genetic information transference in living organisms.

________are small membrane-enclosed compartments that bud of of the er and golgi membrane and may fuse with other membranes of the endomembrane system or plasma membrane.

Answers

Answer:

they are vesicles, which can be secretory vesicles, or even lysosomes

Final answer:

Vesicles, which are a part of the cell's endomembrane system along with the endoplasmic reticulum, Golgi apparatus, and plasma membrane, bud off from the ER and Golgi apparatus, and fuse with other membranes to package, tag, and transport proteins and lipids for cellular membranes.

Explanation:

The structures described in your question are known as vesicles. These are small membrane-enclosed compartments that bud off of the endoplasmic reticulum (ER) and Golgi apparatus and can fuse with other membranes of the endomembrane system or the plasma membrane. They are part of the endomembrane system of a cell which also includes the nuclear envelope, lysosomes, as well as the plasma membrane. The cellular components found in this system work together to modify, package, tag, and transport proteins and lipids, which in turn form cell membranes. For instance, transport vesicles that leave the ER fuse with the Golgi apparatus to process the proteins, and additional transport vesicles containing the modified proteins and lipids pinch off from the Golgi apparatus and move to fuse with the plasma membrane or other organelle membranes.

Using the explicit formula, calculate how far the students will be swimming on week 10 using Ernest's schedule.

Answers

Ernest would be swimming at 3.25 units on week 10

The explicit formula is given as:

$a_n = a_1 + (n - 1) * d$

Also, we have the following parameters

$a_1 =1.0$ -- the initial distance

$d =0.25$ --- the difference between concurrent distances

In week 10, the value of n is 10.

Next, substitute 10 for n in the explicit formula $a_n = a_1 + (n - 1) * d$

So, we have:

$a_(10) = 1.0 + (10 - 1) * 0.25$

Subtract 1 from 10

$a_(10) = 1.0 + 9 * 0.25$

Multiply 9 by 0.25

$a_(10) = 1.0 + 2.25$

Add 1.0 and 2.25

$a_(10) = 3.25$

Hence, Ernest would be swimming at 3.25 units on week 10

How do Trichinella spiralis enter their hosts? a. Through ingestion of undercooked pork b. Through mosquito bites c. Through skin penetration d. Through contaminated water

Answers

Answer:

Trichinella spiralis enter their hosts through ingestion of undercooked pork. When a person consumes raw or undercooked pork that is infected with Trichinella larvae, these larvae can survive in the human digestive system. Once inside the host's body, the larvae develop into adult worms in the small intestine.

Explanation

: To summarize, Trichinella spiralis enter their hosts through the ingestion of undercooked pork.

Where does the energy & phosphates come from to create ATP?

Answers

Answer:

Most of the ATP in cells is produced by the enzyme ATP synthase, which converts ADP and phosphate to ATP. ATP synthase is located in the membrane of cellular structures called mitochondria; in plant cells, the enzyme also is found in chloroplasts.

Explanation:

Answer:

When the cell has extra energy it stores that enrgy

by reattcaching a free phosphate molecule to ADP, turning it back into ATP. The ATP molecule is just lile a rechargable battery.
