Answer:

An organelle is a subcellular structure that has one or more specific jobs to perform in the cell, much like an organ does in the body. Among the more important cell organelles are the nuclei, which store genetic information; mitochondria, which produce chemical energy; and ribosomes, which assemble proteins.

eukaryotes have organelles

What is mRNA?
Deffense [45]

Answer:

Messenger RNA is a type of RNA that is necessary for protein production. In cells, mRNA uses the information in genes to create a blueprint for making proteins. Once cells finish making a protein, they quickly break down the mRNA. mRNA from vaccines does not enter the nucleus and does not alter DNA.

So the answer will be C or A

Which statement best describes the orbit of Earth?
ruslelena [56]

Answer:

B. Earth rotates on its own axis and revolves around the Sun.

Explanation:

The earth moves not only in one way but in two ways. It revolves around its axis and revolves around the Sun.

We do not notice it because we are on Earth and we turn together with it.

When the Earth revolves around its (imagined) axis, we call such a movement a rotation, and when it revolves around the Sun - a revolution.

joost, s. et al. single-cell transcriptomics reveals that differentiation and spatial signatures shape epidermal and hair follic
DerKrebs [107]

A single cell RNA seq analysis identifies 25 population of epidermal cells . 

<h3>What is single cell transcriptomics used for?</h3>

Single cell transcriptomics are being used to create reference maps of healthy human tissues, organs and systems at single cell resolution.

An essential model system for studying stem cells and tissue regeneration is the mouse epidermis with its hair follicles. To demonstrate how the cellular heterogeneity of the murine telogen epidermis is controlled at the transcriptional level, we used single-cell RNA-sequencing in this study. 25 different populations of interfollicular and follicular epidermal cells were identified by impartial clustering of 1,422 single-cell transcriptomes. With previously unheard-of resolution, our data allowed for the reconstruction of gene expression patterns during epidermal development and along the proximal-distal axis of the hair follicle.

Jane learns the relaxation technique of Progressive Relaxation. When Jane gets stuck in bumper-to-bumper traffic on her way home
german

Answer:

It is known as <u>Progressive Muscle Relaxation</u>

<em>b) She alternates muscle tension and relaxation of various muscles in her body.</em>

Explanation:

PMR is a healthy coping skill normally learned in any kind of psychiatric business. For example, I learned PMR while I was inpatient at a behavioral health unit. The way we did PMR was that we'd sit up in our chairs and start from the toes and on up. We squeezed our toes together for a few seconds and then released and then we'd do it a second time. After the toes, it would move up to the feet and we'd use the same process for that and for the rest of the joints.
