Eukaryotic cells are enclosed in the membrane, and the nucleus is bound by a nuclear membrane. Major parts of the eukaryotic animal cell are the nucleus, cytoplasm, mitochondria, Golgi, ER, etc.
What are animal cells?Animal cells are eukaryotes that lack cell walls but have almost the same components as plant cells. The cytoplasm is the component of the cell where all the organelle lies.
The nucleus is the central organ that is involved in genetic replication and transcription and translation. Mitochondria are involved in the metabolic process and release of energy.
Golgi are involved in the packaging and transport of the proteins and ER produces proteins that are transported to the Golgi. Vacuoles though are present in small quantities they aid in the accumulation and elimination of the waste product.

Which two organelles work together to create a functional protein.
Answer:
J
Explanation:
The two organelles that work together to create a functional protein are the ribosome and the endoplasmic reticulum (ER).
What if the function of ER and ribosome?The ribosome is responsible for synthesizing the protein, while the endoplasmic reticulum provides the environment in which the protein can fold into its functional 3-dimensional structure.
In the cytoplasm, the ribosome reads the genetic information in messenger RNA (mRNA) and uses it to assemble a chain of amino acids, forming a protein. The ribosome then transfers the newly-formed protein to the endoplasmic reticulum.
The endoplasmic reticulum is a network of membranes that runs throughout the cytoplasm. It is involved in many cellular processes, including the folding and modification of newly-synthesized proteins. In the ER, the protein undergoes a series of post-translational modifications, such as the addition of carbohydrates, lipids, or phosphate groups. These modifications help the protein fold into its functional 3-dimensional structure and determine its final function in the cell.

What advantages do diatoms obtain from sexual reproduction?a. increased genetic variability.b. increased ability of populations to respond to environmental change.c. evolutionary potential.d. regeneration of maximal cell size for the species.d. all of the above.
Answer:
The correct answer is: option D. all of the above.
Explanation:
In sexual reproduction, two opposite gender gametes are fused together to form a zygote by the process called fertilization which forms the new organism that is genetically unique.
In diatoms, sexual reproduction caused various types of advantages such as higher or enhanced genetic variability as recombination occurs. It also helps the ability to responding to environmental change Increasing the population or species size and other.
Thus, the correct answer is: option D. all of the above.

How do your interactions
with nonliving systems affect your
environment?
Explanation:
Interactions between different organisms are numerous and are usually described according to their positive (beneficial), negative or neutral effect on others.
The interactions between living things and their non living environment makes up a total ecosystem; understanding any one part of it requires knowledge of how that part interacts with the others. Ecosystems do not ‘collapse’ but do change in function, structure and composition over time due to natural or human disturbance (examples include the impact of drought, flooding, mowing and herbicides).

Which statement about enzymes is true? A. An enzyme functions to decrease the rate of a chemical reaction. B. Enzymes are proteins that function as catalysts in nonliving things. C. Each enzyme can catalyze many different biochemical reactions. D. Enzymes and substrates fit together like a lock and key.
Enzymes are proteins that are like keys and fit into the lock called substrate to carry out the reactions. Thus, option D is accurate.
What are enzymes?Enzymes are involved in metabolic reactions and act as catalysts by speeding up the reactions. They do not decrease the activity function of the rate of reactions in the living things.
A specific type of enzyme can catalyst only a single type of substrate and are unique for a reaction. Enzymes and substrates act as lock and key that fits together to carry out the reaction.
The active site of the enzymes is unique and fits into the substrate to form the complex resulting in a product formation.
Therefore, option d. enzyme and substrate are lock and key.

. Name the cells that are produced by the testes and ovaries.
Answer and explanation:
In the female of the species the reproductive cells are the egg cells, and in the male the reproductive cells are the sperm. The male gonad, the testicle, produces sperm in the form of spermatozoa. The female gonad, the ovary, produces egg cells. Both of these gametes are haploid cells. The testes contain germ cells that differentiate into mature spermatozoa, supporting cells called Sertoli cells, and testosterone-producing cells called Leydig (interstitial) cells.

Answer:
[tex]\boxed {\tt D. \ Denaturing \ the \ enzyme }[/tex]
Explanation:
Enzymes are special proteins that speed up chemical reactions. They have specific shapes that correlate to their functions. They also have optimal temperature and pH ranges. They should be in the range for the best results.
If an enzyme is placed in an extreme temperature or pH, the enzyme will become denatured. The enzyme will fold in a different way and its unique shape will be altered. As a result, the enzyme will slow down or stop working.
Therefore, the correct answer is D. denaturing the enzyme.
Which of the following statements regarding restriction enzymes is NOT true?
A) Most restriction enzymes recognize sequences of 20-25 bp in length.
B) Bacteria can add methyl groups to their DNA to prevent digestion by endogenous restriction enzymes.
C) Most restriction enzymes recognize palindromic sequences in host DNA.
D) Restriction enzymes may produce either sticky or blunt ends when digesting host DNA.
Answer:
The correct option is option A
Explanation:
Restriction enzymes are endocleases that cleave DNA fragment (of usually four, five or six nucleotide long) at specific sites to produce blunt or sticky ends. They recognize palindromic sequences of host DNA when cleaving the specific sites. The sequences below (on complementary strands) give an example of a palindromic sequences.
5'-CCC║GGG-3'
3'-GGG║CCC-5'
As can be seen above, when read from 5' to 3', the two sequences are the same despite being on opposing strands. And when cut between the guanine (G) and cytosine (C) (as shown above), it produces a blunt end. But when cut as shown below produces a sticky end.
5'- G║AATTC -3'
3'- CTTAA║G -5'
The explanation above shows options C and D are right while option A is wrong (hence the correct option).
Also, bacteria prevent their own DNA from been digested by restriction enzymes by adding methyl group to their restriction sites which prevents restriction enzymes from recognizing restriction sites of their DNA; this generally makes bacterial DNA to be highly methylated. This explanation makes option B right also.
Autism is a neurological disorder thought to be caused by mutant alleles of one or more genes. Scientists had been wondering why the number of children diagnosed as autistic increased dramatically in a decade, from 1 in 500 in 2002 to 1 in 88 in 2012. Researchers now think that they might have found at least part of the answer: Men are fathering children at later and later ages. A paper published in the journal Nature in 2012 showed a correlation between paternal age and the incidence of autism; the age of the mother was not a factor. How does this observation provide a possible explanation for the apparent increase in the rate of autism?
Answer:
There is an accumulation of genetic mutations in the DNA of sperms due to its constant mitosis.
Explanation:
The germinative cells that will become sperms are under constant mitosis. During this process, DNA mutations can happen and be transmitted from one generation of cells to the other as the years go by, and more cell divisions take place, more mutations the DNA in the sperm will have. When the number of mutations reaches a certain level, his child will express these mutations and have autism.
The egg of the mother is not a factor because the germinative cells in women are not under constant mitosis, so there is not an accumulation of gene mutations. Women are born with an exact number of eggs for all their life.
