Biology
1 answer:
Kobotan [32]3 years ago
3 0

Answer:

Testes are the structure in male organism where sperm cells are produced. The process in which sperm cells are produced called spermatogenesis. Ovaries are the structure in female organism where egg cells are produced. The process in which egg cells are formed is called oogenesis.

When sperm of male combine with egg of female, it produces a fertile zygote and this zygote turns into a new organism.

The fundamental resolution of an optical instrument is set by
yaroslaw [1]

Answer:

The wave nature of light is the fundamental resolution of an optimal instrument.

Explanation:

All the optical instruments are working on light that's why they are known as optical instrument. Optics means the behavior of light or sight. Light is an electromagnetic radiation which comes in the category of electromagnetic spectrum. It travels in the form of wavelength.

So, optical instruments are based on wave nature of light.

Which statement would be true of a membrane-bound protein that works in conjunction with a sodium–potassium pump during secondar
Rudik [331]

Answer:

The correct answer is option d. "Its conformation will change when both an ion and a small molecule bind to it".

Explanation:

The secondary active transport is a form of active transport at which a ion (typically Na+ or H+)  is transferred down its electrochemical gradient to the uphill movement of another molecule. Secondary active transport takes place by the conjunctive work of membrane-bound proteins and sodium–potassium pumps. During secondary active transport, both of these proteins change its conformation when an ion and a small molecule bind to it. This change in conformation makes possible that the ions and the small molecules pass through the membrane.

1) How is DNA condensed to form a chromosome?
frosja888 [35]

Answer:

Hello! Here are the answers:

  1. Chromosomes are a highly condensed form of a combination of DNA and protein called chromatin. DNA strands (negatively charged) are tightly wound around these proteins called histones (positively charged) to form chromosomes.
  2. Mechanism genes code for for proteins that govern life processes. These genes or portions of DNA  are called exons. DNA segments between these exons are called introns that strictly code for regulatory proteins and also contain genetic regulatory elements (DNA sequences that control gene expression).
  3. Gene expression is the process of translation of DNA sequences into proteins. The genetic code is the nucleotide sequence in the DNA itself that codes for different amino acids that combine together to form a functional protein.

Explanation:

* 2. The intronic regions are misleadingly referred to as "junk DNA" but introns code for crucial regulatory elements that control gene expression.

* 3. The genetic code determines the sequence of amino acids in various proteins.
