1. Indicate all statements that are true. A. Haploid cells are only generated by meiosis B. Diploid cells are only generated by
zubka84 [21]

Answer: Option A, B and F.

Explanation:

Haploid cells are produced during meiosis. Meiosis is a type of cell division that reduces the number of diploid cell parent chromosomes to half number of chromosomes producing haploid cells.

Haploid cells contain half number of parent chromosomes.

Diploid cells is generated during Mitosis.

Mitosis is a type of cell division in which the parent cell divided to produce two daughter cells( diploid cells) which contain the full number of parent chromosomes.

Diploid cells can be generated by fusion.

Diploid cells is produced when two haploid cells fuse together.

All muscle types will respond to an electrical stimulus because all muscle cells are _________.
irakobra [83]

Answer:

excitable

Explanation:

All muscle types will respond to an electrical stimulus because all muscle cells are excitable.

Excitability is response of muscle to signal which delivered through the motor neuron.

Excitability is stretching of muscles.

The contraction and relaxation of muscle occur in following way:

Muscle contraction begins with signal. The contraction occur when nervous system send signals. The impulse which is called signal is travel through a motor neuron.

The whole process include following three steps:

1) Message is traveled from nervous to muscular system and trigger the chemical reaction.

2) This chemical reaction causes the muscle fibers to reorganize in such a way that shorter the length of them which is called contraction.

3) when this signal is no longer remain , reverse chemical process occur and muscles relax.

Please help!!
Nikitich [7]

Answer:

1. d.water comes "out of" or "exits" the reaction

2. a.energy goes "into" or "enters" the reaction

3. Path A

Explanation:

1) Peptide bond synthesis is dehydration reaction which means water is "dehydrated" meaning released when the reaction occurs.

2) Anytime we want to join things together we gotta use energy, these processes are anabolic reactions such as making sugars, proteins, lipids, in our cell. Since we are making protein here, we need to put energy into the reaction.

3) Path A is hydrophobic b/c they directly diffuse thru cell membrane to attach to intracellular receptor.

My best attempt, hope its right.

An atom has an 16 protons, 18 neutrons, and 13 electrons. What are its atomic number, atomic mass, and net charge?
joja [24]

Atomic number = number of proton = 16

Atomic mass = number of proton + number of neutron = 16+18 = 34

Net charge = Number of proton - number of electron = 16-13 = +3
