What amino acids are being carried by the tRNA
Answer:
Explanation:
Each tRNA can only carry one amino acid. The tRNA CODES for ONE amino acid through its 3 base codons. The 3 codons result in a possibility of 64 combinations and since 3 of those 64 code for STOP there are a potential 61 amino acids coded for by a tRNA, but each tRNA only carries one of those potential amino acids. read more

Please help!!! how can a sedimentary rock become a sedimentary rock???
Answer:
Sedimentary rocks are made of sand, gravel, mud and other materials. They go through a 5 step process to be made.
Explanation:
1) first weathering breaks down material that will be used to form the rock.
2) next erosion picks up the sediment via wind, water, or glacier
3) the sediment is then transported via wind, water, or glacier
4) Then deposition occurs. (depositing the sediment)
5) Lithification (turning the sediment to rock)

what is the role of the blood vessels
Answer:
Blood vessels are the channels or conduits through which blood is distributed to body tissues. The vessels make up two closed systems of tubes that begin and end at the heart. One system, the pulmonary vessels, transports blood from the right ventricle to the lungs and back to the left atrium.
Explanation:
Neurons, as with other excitable cells in the body, have two major physiological properties: ____________ and ____________. A neuron has a positive charge on the outer surface of the cell membrane due in part to the action of an active transport system called the ____________. This system moves ____________ out of the cell and ____________ into the cell. The inside of the cell membrane is negative, not only due to the active transport system but also because of ____________, which remain negative due to the intracellular pH and keep the inside of the cell membrane negative.
Answer:
Neurons, as with other excitable cells in the body, have two major physiological properties: irritability and conductivity. A neuron has a positive charge on the outer surface of the cell membrane due in part to the action of an active transport system called the sodium potassium pump. This system moves sodium (Na+) out of the cell and potassium (K+) into the cell. The inside of the cell membrane is negative, not only due to the active transport system but also because of intracellular proteins, which remain negative due to the intracellular pH and keep the inside of the cell membrane negative.
Explanation:
Neurons are cells with the capacity to transmit information between one another and also with other tissues in the body. This information is transmitted thanks to the release of substances called neurotransmitters, and this transmission is possible due to the electrical properties of the neurons.
For the neurons (and other excitable cells, such as cardiac muscle cells) to be capable of conducting the changes in their membranes' voltages, they need to have a resting membrane potential, which consists of a specific voltage that is given because of the electrical nature of both the inside and the outside of the cell. The inside of the cell is negatively charged, while the outside is positively charged - this is what generates the resting membrane potential. When the membrane voltage changes because the inside of the cell is becoming less negative, the neuron is being excited and - if this excitation reaches a threshold - an action potential will be fired. But how does the voltage changes? This happens because the distribution of ions in the intracellular and extracellular fluids is very dissimilar and when the sodium channels in the cell membrane are opened (because of an external stimulus), sodium enters the cell rapidly to balance out the difference in this ion concentration. The sudden influx of this positively-charged ion is what makes the inside of the neuron become less negative. This event is called depolarization of the membrane.

Which of the following is true regarding how epithelial tissue and connective tissue relate to each other?
a. Although their structures are different, both include a large amount of extracellular material between cells.
b. Both are composed of cells, ground substance, and protein fibers.
c. Neither of them provide protection as a main function.
d. Unlike epithelial tissue, which is composed of cells closely packed with little or no extracellular space in between, connective tissue cells are dispersed in a matric
Answer:
d. Unlike epithelial tissue, which is composed of cells closely packed with little or no extracellular space in between, connective tissue cells are dispersed in a matric
Explanation:
There are four primary types of tissues in living organisms. Epithelial and connective tissues are two of those four types of tissues. Epithelial tissues are made up of closely packed cells that serve functions such as absorption, secretion, protection, etc while connective tissues are composed of cells, ground substance, and protein fibers that serve supportive functions.
The cells of epithelial tissues are so closely packed to one another that there is hardly space in their extracellular matrix for materials. However, on the contrary, connective tissues are made up of cells that have room for large quantities of extracellular matrix. Hence, the cells that make up connective tissues are dispersed into matrix.
Drag the terms on the left to the appropriate blanks on the right to complete the sentences.
1. The epithelial membrane that lines the closed ventral cavities of the body.
2. The epithelial membrane that lines body cavities open to the exterior membrane
3. Consists of keratinized stratified squamous epithelium.
4. Found lining the digestive and respiratory tracts.
5. Makes up the pleura and pericardium.
6. Lines blood vessels and the heart.
Answer:
Some of these sentences both refer to the same term.
1. The epithelial membrane that lines the closed ventral cavities of the body. - 5. Makes up the pleura and pericardium. This is called the serous membrane.
2. The epithelial membrane that lines body cavities open to the exterior membrane . - 4. Found lining the digestive and respiratory tracts. These statements refer to the mucous membrane.
3. Consists of keratinized stratified squamous epithelium. - cutaneous membrane.
6. Lines blood vessels and the heart. - endothelium.
Explanation:
All of these membranes are formed by epithelial tissue - one of the four basic tissues found in the human body, with important tasks that many times give the organs they're part of their main function.
The epithelium can vary in shape and size in order to adapt to the necessities of the organ. If the organ needs protection from abrasions, like the skin or the stomach, this tissue will have many layers and be called "stratified epithelium". On the other hand, an organ with the function to exchange substances, like the blood vessels or the alveoli, will have only one layer of epithelium, to ease the diffusion of gases and other molecules.
The other three basic tissues are: connective tissue, muscle tissue, and nervous tissue.

How do interdependent factors—such as climate and lack of resources—impact the carrying capacity of an ecosystem?
Answer:
Ecosystems have carrying capacities, which are limits to the numbers of organisms and populations they can support. These limits result from such factors as the availability of living and nonliving resources and from such challenges such as predation, competition, and disease. If this helps you could I possibly have brainliest?
Explanation:
The impact of climate and lack of resources on the carrying capacity of an ecosystem is discussed below :
The carrying capacity of an ecosystem can be described as the maximum amount of organisms which can be naturally catered for giving the resources available in an environment.
Climate has an important role to play in the type of resource available or resources which can thrive in an environment. Similarly harsh climate conditions aren't favorable for survival, hence resulting in low carrying capacity of such ecosystem.
Also, organisms, animals depend on the available resources available in an environment for survival, when the available resources aren't enough to cater for a large population, the carrying capacity of the ecosystem is impeded.
