If Tyler does not eat a diet that includes essential amino acids, his cells will not be able to build
Answer:
Essential amino acids are constituents for proteins associated with energy production, growth, nutrient absorption, and immunity. Thus, if Tyler does not take a diet having essential amino acids, he will not be able to build some kinds of proteins as amino acids are building blocks for proteins.

What is a working copy of DNA and is read by organelles called?
Answer:
Working copy of DNA is RNA (Ribonucleic acid)
The nucleus controls all of the cell’s activities, such as growth and metabolism, using the DNA’s genetic information.
Answer:
messenger RNA (mRNA)
Explanation:
The working copy of the DNA is called messenger RNA (mRNA). Its ready by organelles such as ribosomes to manufacture amino acids to make proteins.
In both prokaryotes and eukaryotes, initiation of translation usually
a. begins immediately upstream of a Shine-Dalgarno sequence.
b. requires the action of release factors, which cause the small and large subunits of a ribosome to associate with one another.
c. requires the action of initiation factors.
d. begins at a UAG codon downstream of the 5’ UTR of an mRNA molecule.
e. begins only after ubiquitin has been added to the mRNA molecule to be translated.
Answer:
c. requires the action of initiation factors.
Explanation:
Transcription is the process by which a fragment of DNA (e.g., a gene) is used as a template to create a complementary RNA molecule, usually a messenger RNA (mRNA) molecule which is then used to synthesize a polypeptide chain (i.e., a protein) in the ribosomes by a process called translation. Initiation factors are proteins capable of binding the ribosome in order to promote (or prevent) the initiation of translation. In prokaryotic cells, the initiation factors IF1, IF2 and IF3 (IFs) are required for the selection and the quantity of the protein produced. In eukaryotic cells, translation initiation occurs when an initiator tRNA, 40S, and 60S ribosomal subunits are assembled by eukaryotic initiation factors (eIFs) into an 80S ribosome on the initiation codon of an mRNA. In eukaryotes, translation initiation is promoted and regulated by at least twelve eIFs (e.g., eIF1, eIF1A, eIF2, eIF3, eIF4, eIF5, eIF5A, eIF5B, etc) which are composed of many polypeptides.

Explanation:
i just need brainly points man sorry
Catalase is an enzyme observed in organisms exposed to oxygen. This enzyme acts to catalyze the conversion of hydrogen peroxide (H2O2) into water and oxygen.
The discovery of a CATALASE-encoding gene provides evidence that the microbe can grow in the presence of oxygen.Catalase is a key enzyme that protects the cell from oxidative stress damage.Catalase acts together with the enzyme superoxide dismutase, which in turn catalyzes the formation of H2O2 from superoxide radicals.In conclusion, the discovery of a CATALASE-encoding gene provides evidence that the microbe can grow in the presence of oxygen.

A relationship in which one species kills and consumes another species is known as
predation.
parasitism.
commensalism.
mutualism.
A relationship in which one species kills and consumes another species which is called as the Predation. So, the correct option is A.
What is Predation?Predation is defined as the relationship in which one species kills and consumes another species. It is a type of community relationship in which organisms of one species, also known as predator, consume the tissues of organisms of another species, called prey, which means killing the prey and killing all or most of the prey organisms.
Herbivores are explained as predators in which the prey organism is a plant. Predation is described as the natural way of transferring the energy fixed by plants to higher trophic such as snake eating a frog tiger killing and eating a deer.
Therefore, the correct option is A.

Monocercomonoides are a genus of single-celled organisms that live as parasites in the guts of small animals. They lack mitochondria, but other evidence shows them to be most closely related to members of the excavates. Looking at the tree for eukaryotes, what can you conclude about the Monocercomonoides?
A. Since excavates are eukaryotes, it is extremely unusual for one of them to lack mitochondria.
B. Excavates branched off before the evolution of mitochondria, so the absence is not surprising.
C. Since they are parasites of animals, they should be placed within the opisthokont branch of the tree.
D. A phylogenetic tree reflects evolutionary relationships, so they should be placed within the excavates.
E. Their lineage likely had mitochondria but lost them at some point.
Answer: A. Excavates branched off before the evolution of mitochondria, so the absence is not surprising.
C. Since they are parasites of animals, they should be placed within the opisthokont branch of the tree.

Legend has it that there was a less famous geneticist in the 1800s
named Megor Grendel. He did his experiments with the cats that lived in the monastery's barn. Here are some results from one of his 16 crosses:
Cross #3 Maggie (orange) x ? (possibly Tom, or maybe Bill)
Kittens:
1. light orange female
2. dark orange male
3. black female
4. light orange female with white paws
5. black male with white paws
6. orange ? (sex undetermined; died at birth)
Answer:
Few crosses
The complexity of cat genetics
Crosses not controlled by the researcher
Explanation:
The purpose of this question is to determine why Megor Grendel is less famous than that of Gregor Mendel.
Gregor Mendel examined pea plants, which have a number of benefits for deducing genetic rules, including:
The researcher has total control over the crosses. Because the peas have both self and cross-fertilization, it is possible to alter the crosses in the simplest way possible. Pea plants may be examined for a greater series of generations than cats or other animals. Because plant genetics is not overly complicated, several traits may be investigated at the same period.As a result, the primary factors why Megor Grendel's experiments are not well-known:
The presence of only a few crossings: It is impossible to establish a genetic theory with such a small number of crossings on the test subject of the organism. Cat genetics is too complicated therefore, the fur gene color on the X-chromosome, a characteristics mosaic inheritance. As a result, It is much too complicated to deduce an inheritance pattern. Crossings that the researcher cannot fully control. Unlike plants, crosses in animals cannot be totally controlled by the researcher.As a result, it is impossible to draw any conclusions from them.

When curare, a neuromuscular poison, is dropped onto an isolated muscle-nerve preparation in a laboratory, the muscle does not contract when the nerve is stimulated, even though neurotransmitter is released from the nerve cell. Why does this happen
Answer:
Explanation:
Whenever the nerve terminal's action potential depolarizes, calcium enters the cell through the channels. Calcium allows acetylcholine (ACh) to be released more easily. These ACh molecules subsequently circulate into the synaptic cleft and attach to the motor end-plate of the nicotinic cholinergic receptors. Acetylcholine molecules connect to nicotine ion-channel receptors present on cell membrane the of muscle cells, enabling the ion channels to open. Calcium ions then enter the muscle cell, kicking off a series of events that eventually result in muscular contraction.
Curare is a kind of neuromuscular relaxant blocker that is non-depolarized in nature. Nondepolarizing muscle relaxants work as competitive agonists, binding to ACh receptors but failing to activate ion channels. As a result, they inhibit ACh from bonding, preventing the development of endplate potentials and inducing muscle paralysis.

B. Mutations in sex cells can be passed on to children.
c
C. Mutations in sex cells are chromosomal mutations.
a
D. Mutations in sex cells are silent mutations,
Answer:
B
Explanation:
B
A mutation in a sex cell (sperm or egg cell) differs from a mutation in a non-sex cell (somatic cell) in several ways: . Mutations in sex cells can be passed on to children and Mutations in sex cells are chromosomal mutations and may more.
How are mutations can be passed on to children ?Mutations in sex cells can be passed on to children: When a mutation occurs in a sex cell, it can be passed on to the offspring and become a hereditary condition. On the other hand, mutations in non-sex cells cannot be passed on to offspring.
C. Mutations in sex cells are chromosomal mutations: Sex cells contain chromosomes, and mutations in these cells can result in chromosomal abnormalities that can affect the development and health of the offspring.
Thus, A and D are incorrect. Mutations in sex cells are not necessarily more deadly than mutations in non-sex cells, and they are not always silent mutations. The effects of a mutation depend on its location and the function of the gene affected.
