Which of the following statements about the nuclear envelope is false?

a) Nuclear pores are made up of a group of proteins that are collectively called the nuclear pore complex.
b) The nuclear envelope is continuous with the Golgi apparatus.
c) The nuclear envelope is composed of two lipid bilayers.
d) Molecules pass into and out of the nucleus through nuclear pores.

Answers

Answer 1

Answer:

b) The nuclear envelope is continuous with the Golgi apparatus.

Explanation:

The nuclear envelope is a nuclear membrane composed of two lipid bilayers: inner and outer membrane and perinuclear space between them. Its outer membrane is continuous with the endoplasmic reticulum. Nuclear pores that are part of this envelope allow the movement of molecules in and from the nucleus (e.g. mRNA formed during transcription should be transported into cytosol through the pores).

Which of these statements about the hip joint is false? It permits circumduction.

Answers

it permits circumduction

The false statement about the hip joint is: b. It has a biaxial design.

However, stating that the hip joint has a biaxial design is incorrect. The hip joint is a ball-and-socket joint, which means it allows movement in multiple directions, not just two. It permits movements such as adduction, abduction, flexion, extension, internal rotation, and external rotation.

a. The hip joint permits adduction, which is the movement of the thigh toward the midline of the body.

c. The hip joint permits flexion, which is the movement of bending the thigh toward the abdomen.

d. The hip joint permits extension, which is the movement of straightening the thigh backward.

Therefore, the correct statement would be that the hip joint has a multiaxial or triaxial design rather than a biaxial one. Additionally, all hip joints in humans permit circumduction due to their structure and the muscles that act upon them.

The complete question is:

Dna is located in the nucleus of the cell and makes up the_________

Answers

Dna is located in the nucleus of the cell and make up the chromosomes.

Every cell has a nucleus that carries DNA. In the DNA, thread-like structures are formed and are known as chromosomes. The chromosome are coiled up and tightly wrap around proteins.

Final answer:

DNA is in the nucleus of the cell and forms the organism's genetic material. It contains the information needed for growth, development, and reproduction. The genetic material is organized into structures called chromosomes.

Explanation:

DNA, which stands for deoxyribonucleic acid, is located in the nucleus of the cell and makes up the genetic material of the organism. It is a molecule that contains information that an organism needs for growth, development, functioning, and reproduction. This genetic material is organized into structures called chromosomes. For example, in humans, DNA is organized into 23 pairs of chromosomes.

How many hydrogen bonds are found between a-t

Answers

The correct answer is two hydrogen bonds between adenine and thymine (the bond is thus weaker and longer) and three between cytosine and guanine.

A hydrogen bond is a bond formed between a hydrogen (H) atom and electronegative atom or group, such as nitrogen (N), oxygen (O), or fluorine (F).

Hydrogen bond is found in the double helical structure of DNA between its base pairs. Guanine is complementary linked with cytosine and adenine with thymine. Thanks to hydrogen bonds one complementary strand is connected to the other and replication is enabled.
