An elderly person has a stroke that leaves her unable to talk and part of her body paralyzed. which part of the body is most lik
Lostsunrise [7]

Left brain of the body is most likely to be paralyzed

If the stroke occurs in the left side of the brain, the right side of the body will be affected, producing some or all of the following: Paralysis on the right side of the body. Speech/language problems.

<h3>What is a Stroke ?</h3>

A stroke is when a portion of the brain loses blood supply. It occurs when a blood clot narrows an artery in the brain or when pressure builds up there due to a blood vessel in the head bleeding. Both scenarios result in the death of brain cells and either temporary or permanent brain damage.

  • A blocked artery (ischemic stroke) or a blood vessel leak or burst are the two basic causes of stroke (hemorrhagic stroke). Transient ischemic attacks (TIAs), which are brief interruptions in blood supply to the brain that don't persist long, can occur in some persons.

Need help with the following questions
worty [1.4K]
MRNA: AUG AAU UUA GCG ACA
polypeptides: Met or start, Aan, Leu, Ala, Thr
1. The type of mutation that occurred in this strand of DNA is deletion. This may have happened because a small part of the DNA sequence was lost when broken ends were rejoined when the DNA was being repaired. 
2. It is not likely that these mutated genes could produce a working protein because the polypeptides were completely changed, which would cause the protein to not work properly.
3. When a seed first absorbs water, it begins to grow. The mutation could cause the plant to be unable to absorb water. Therefore, the plant would be unable to germinate.

Name two structural and two functional properties of proteins
Inga [223]
1.Proteins are linear polymers built of monomer units called amino acids. The construction of a vast array of macromolecules from a limited number of monomer building blocks is a recurring theme in biochemistry. Does protein function depend on the linear sequence of amino acids? The function of a protein is directly dependent on its threedimensional structure.<span>Remarkably, proteins spontaneously fold up into three-dimensional structures that are determined by the sequence of amino acids in the protein polymer. Thus, </span>proteins are the embodiment of the transition from the one-dimensional world of sequences to the three-dimensional world of molecules capable of diverse activities<span>.

</span>2.Proteins contain a wide range of functional groups<span>. These functional groups include alcohols, thiols, thioethers, carboxylic acids, carboxamides, and a variety of basic groups. When combined in various sequences, this array of functional groups accounts for the broad spectrum of protein function. For instance, the chemical reactivity associated with these groups is essential to the function of </span>enzymes,<span> the proteins that catalyze specific chemical reactions in biological systems</span><span>

Eutrophication can cause excess algae growth. Which of the following describes how nutrients contribute to eutrophication?
dusya [7]

Eutrophication of water bodies like lake, pond, shallow stretches of river, etc. is the phenomenon where excess growth of vegetation on the surface of the water takes place. This excess growth results in the clouding of the water, depletion of dissolved oxygen in water, and the death of aquatic organisms. The primary reason for the cause of eutrophication is the presence of nutrients in excess amounts in the water. The nutrients B. come from fertilizer and sewage runoff.
