<span>Gyri and sulci are the folds and grooves, respectively, which characterize the surface of the human brain.</span> Gyri are part of the brain that shows a larger surface of the brain. When the gyri change in structure or form it shows that a body is encountering sickness and disorders. Sulci is one of the part of the cerebral cortex that surrounds the gyri.

Contrast the different ways bromeliads and pitcher plants acquire nutrients from animal sources. NOT COMPARE.
dezoksy [38]
<span>Bromeliads are an example of mutualism where they create mini-ecosystems that house other small animals by collecting rainwater in their leaves. The bromeliad benefits from the nutrients when these organisms decompose when they die. Unlike the Pitcher plants which are predators, they actively trap insects and other small animals in their pitchers.

Which of the following represents an isotope for lithium (73Li)?
NARA [144]

Answer:

The correct answer is - option b) 3Li .

Explanation:

Lithium that is occurring naturally have two isotopes that are stable one with an atomic mass of 7 and the other with an atomic mass of 6 both have the same atomic number.

In question 7(atomic mass) 3 (atomic number) is given and there is only two option have 3 atomic number with 3 b) 3.Li and d) 43Li. 4 atomic mass is not naturally occurring isotopes and as option b) has a no atomic mass so it would be the correct answer.

Thus, the correct answer is - option b) 3Li .

A hydra is an aquatic organism that lives in fresh water. During reproduction an outgrowth begins to form on the parent. The out
maksim [4K]

The answer is; asexual reproduction

In specific, this type of asexual reproduction is called budding. In this type of reproduction, the offspring is completely identical to the parent and there is little room for variation as in the case of sexual reproduction. Other living organisms that exhibit this type of reproduction are yeast, bacteria, and protozoans.

Explain how the data from your experiments showed that cyanide was used to poison Jared, and that 2-deoxyglucose, arsenic and ol
Aliun [14]

The question is incomplete as the background of the case and symptoms of Jarod is not provided, however, the missing data required for the question is as follows:

Jared was investigating a drug cartel and ate a meal with one of the suspects. After the meal, he had trouble breathing and felt weak and dizzy. Jared may have been poisoned. He is being taken to the CIA hospital for treatment. You are a medical toxologist working for the CIA. It is your job to find out what poison was given to Jared and try to save his life. Patient: Jared Sondheim Age: 32 Occupation: CIA Agent Symptoms: Muscle Weakness Shortness of Breath Dizziness. Jared has arrived at the hospital! It is your job to find out what toxin was used to poison Jared. You can then give him the correct antidote to save Jared's life.

Answer:

Poisning by 2-deoxyglucose syops the glycolysis process which leads to cardiovascular and respiratory symptoms. Due to property of inhibiting the enzyme reqquired for glycolysis, glucokinase. So, there is no ATP production takes place.

Arsenic poisoning inhibits the second stae of cellular respiration, the Krebs cycle which leads to pyruvate accumalation. The symptoms associated with arsenic are diarrhea, sking tone, abdomunal pain, and muscle cramps.

Oligomycin is used as an antibiotic to inhibit proton ATPase present in mitochondria membrane which blocks ATP formation. Watery eyes, cough, congestion in chest and nose are sysmptopms of oligomycin poisining.

The symptoms cyanide poisoning are dizziness, short breath, nd muscle weakness which matches with the symptoms of jarod.

A biologist at World University used Procedure IV to conduct an additional study and found the sequence following below. Using y
Nady [450]

Answer:

Valine-Leucine-Proline-Lysine-Histidine

Explanation:

The central dogma of biology is the process by which DNA is used to synthesize RNA and subsequently amino acid sequence (PROTEIN). The processes of transcription and translation is used in gene expression. Transcription is the process whereby the information encoded in a DNA molecule is used to synthesize a mRNA molecule. Transcription is catalyzed by RNA polymerase enzyme, which uses complementary base pairing rule i.e Adenine(A)-Thymine(T), Guanine(G)-Cytosine(C) pairing.

N.B: Thymine is replaced by Uracil in the mRNA

For the above DNA sequence: CAC GAC GGA TTC GTA, the mRNA sequence will be: GUG CUG CCU AAG CAU

Translation is the second process of gene expression which involves the synthesis of an amino acid sequence from an mRNA molecule. The mRNA is read in a group of three nucleotides called CODON. Each codon specifies an amino acid (see attached image for genetic code)

Based on the attached genetic code, an mRNA sequence: GUG CUG CCU AAG CAU will encode an amino acid sequence: Valine(Val) - Leucine (Leu) -Proline (Pro) -Lysine (Lys) - Histidine (His).

GUG specifies Valine amino acid

CUG specifies Leucine amino acid

CCU specifies Proline amino acid

AAG specifies Lysine amino acid

CAU specifies Histidine amino acid
