Cellular respiration definition ?

Answers

Answer:

cellular Respiration is that cells use oxygen in mitochondria to make ATP and GTP for cells

Answer:

Cellular respiration occurs when cells utilize oxygen in their mitochondria to produce ATP and GTP.

Cellular respiration is a series of reactions that occur under aerobic conditions and result in the production of large amounts of ATP.

Explanation:

Glucose, the basic building block for starch and many sugars are one of the main sources of energy in our diet. Its oxidation can be divided into three phases in the respiration of the cells: glycolysis, the cancer cycle, and the electron transport system.

Aerobic breathing uses eukaryotes to generate energy, including all multicellular organisms and some single-cell organisms. Aerobic breathing uses oxygen – a powerful, in-kind electron acceptor.

Aerobic breathing is an extraordinarily effective process that enables eukaryotes to have complicated life and active lifestyles. It also means however that they need a continuous supply of oxygen or that they cannot get the energy to stay alive.

Other forms of respiration, which are slightly less efficient, can be used by procharian organizations such as bacteria and archaebacteria. They can therefore live in environments in which eukaryotic organisms cannot live because they do not need oxygen.

B. Different genes are expressed due to their environment.

Explanation:

I think it's this one because it makes the most sense, but I'm still not sure sorry

Answer:

B. Different genes are expressed due to their environment.

Explanation:

Some identical twins can have different heights and weights. This is because height and weight are controlled by what you eat as well your DNA. Differences in diet can start earlier than you might imagine. When the twins are growing inside the uterus, there can be differences in how well they connect to the placenta.

Answers

Answer:

The correct answer is - are found on microtubules in cilia and flagella and cause movement by grabbing and pulling at adjacent microtubule doublets.

Explanation:

Dynein feet or arm is made up of dyneins a family of cytoskeletal motor proteins that present on microtubules in flagella or cilia or both and drives the beating motion of cilia and flagella.

These form the rows of arms or feet inside and outside, associated with the doublet microtubules of motile cilia that produce microtubule sliding to move along. It gets its energy through ATP hydrolysis.

What are the negative assay results?

False-negative blocks haven't received as much attention as false positives, but they can lead to misdiagnosis and improper treatment candidate selection. Based on the failure of local anesthetic infiltration to relieve the pain from facet joint capsular distention, research on 15 volunteers who had MBBs with local anesthetic or saline and capsular distention estimated the rate of false-negative blocks to be 11%.

It was determined that "aberrant innervation" was a likely explanation for some instances of unsuccessful RF denervation in IA block responders. Vascular uptake is regarded to be one of the main sources of false-negative blocks. According to reports, this can vary from 6% to 30% per level. rates of 3.9% at cervical levels, 3.5% at lumbar levels, and 0.7% at thoracic levels, according to one research.

According to one study, even if the needle is relocated when vascular uptake happens, analgesia will only be experienced 50% of the time. Digital subtraction angiography has been demonstrated to increase the detection rate and is the most reliable method of identifying vascular uptake. Failure to distinguish between procedure-related discomfort and baseline pain, as well as missing a target nerve or nerves, are other potential reasons for false-negative blocks.

Therefore, a false negative result could be the result of low concentration.

Proteins secreted by Gram-negative cells face multiple obstacles, including _____. Multiple choice question. moving across the periplasmic space underlying the thick peptidoglycan layer of the cell wall moving across the plasma membrane moving across the plasma membrane and the thick peptidoglycan layer of the cell wall moving across both the plasma membrane and the outer membrane

Answers

Answer:

moving across both the plasma membrane and the outer membrane

Explanation:

Gram-negative bacteria are bacteria that have a plasma membrane, a thin peptidoglycan layer, and an outer membrane (the space between the plasma membrane and the outer membrane is known as periplasm). Moreover, Gram-positive bacteria exhibit neither outer membrane nor periplasmic space and are surrounded by thick layers of peptidoglycan. Gram-negative bacteria have developed different protein secretion systems (types I–VI and type VIII) in order to secrete proteins into the extracellular space. For such purpose, the XcpQ protein (which is an outer membrane protein from the secretin family) participates in different transport processes in Gram-negative bacteria.

Explanation:

mRNA or messenger RNA is one of the three types of RNA molecules (the other being tRNA and rRNA) that is specifically responsible for carrying genetic information previously encoded and stored in the DNA into the ribosomes for translation to occur.

The process of translation results to the synthesis of amino acid sequences, which make up a polypeptide. Hence, it can be said that mRNA is that type of RNA that acts as a temporary copy of DNA's instructions and provides details on how to assemble a polypeptide chain.

Answers

Answer:

t=v/a

Explanation:

To solve for Time

Since acceleration is change in velocity/time

a=v/t

Cross multiply

a×t=v

at/a=v/a

t= v/a

As surface water in a lake cools from 4 °C to 0 °C, the water expands and becomes less dense. Why is this change in the water beneficial to the organisms living in the lake? As the water cools to freezing, spaces form between water molecules, providing microhabitats for small organisms. Frozen surface water insulates the water below it, maintaining a habitat where organisms can overwinter. Cooler water is less viscous than warmer water, making it easier for organisms to move through the water. Less dense water holds more dissolved compounds, keeping water from freezing so organisms survive winter.

Answers

Answer:

As the water cools to freezing, spaces form between water molecules, providing microhabitats for small organisms.

Explanation:

This change in the water is beneficial to the organisms living in the lake because the water which freezes formed spaces between water molecules, that providing microhabitats for small organisms. The cold temperature causes formation of ice crystals on the surface of water which work as an insulator whereas the lower part of the water remain warm and the organisms can survive in that environment.
