(1) Addition of the first GlcNAc oligosaccharides to the asparagine residue of a protein
(2) Synthesis of phosphatidylcholine
(3) Degradation of misfolded ER protein
(4) O-linked glycosylation

Answers

Answer 1

Answer:

EELG

(1) Addition of the first GlcNAc oligosaccharides to the asparagine residue of a protein occurs in the Lumen of the Endopslamic Reticulum

(2) Synthesis of phosphatidylcholine occurs in the Endoplasmic Reticulum

(3) Degradation of misfolded ER protein ossurs in the Lysosome

(4) O-linked glycosylation occurs in the Golgiapparatus

Explanation:

1. The covalent attachment of a carbohydrate to a macromolecule such as proteins or lipids is known as glycosylation.

N-linked glycosylation is a very common form of glycosylation and it occurs in eukaryotes in the lumen of the endoplasmic reticulum.

The addition of the first GlcNAc oligosaccharides to the asparagine residue of a proteinmos an example of N-linked glycosylation.

2. Phosphatidylcholine is synthesized through the CDP-choline pathway which occurs at the cytoplasmic face of the endoplasmic reticulum. Choline entering the cell is immediately phosphorylated by choline kinase, converting choline to phosphocholine.

Phosphocholine is then converted to CDP-choline by the second enzyme in the pathway, CTP:phosphocholine cytidylyltransferase (CT).

The phosphocholine moiety is then added to diacylglycerol in a reaction catalyzed by CDP-choline:1,2-diacylgylcerol cholinephosphotransferase to complete the synthesis of phosphocholine.

3. Lysosomes are the cell organelles which are responsible for the breakdown of proteins as well as other components of the cell. Misfolded proteins are identified and transported to lysosomes through chaperone-mediated autophagy, macroautophagy and endocytosis, where they are then degraded.

4. O-linked glycosylation is a form of glycosylation that occurs in eukaryotes in the Golgi apparatus.

Echolocation
Nocturnal hunting
Eating insects
Powered flight

Answers

Echolocation is the answer

The unique ability of bats as compared to other mammals is Echolocation. So, the correct option is A.

What do you mean by Echolocation?

Echolocation may be defined as a physiological process for locating distant or invisible objects by means of sound waves reflected back to the emitter by the objects.

Echolocation is the unique ability of bats that have the capability to identify objects rather than seeing, while other mammals identify objects with help of sight.

Therefore, The unique ability of bats as compared to other mammals is Echolocation.

Distinguish between phenotype and genotype.

Answers

Explanation:

Phenotype is the PHyiscal trait e.g height, eye colour and blood type.

Genotype is the GENE of the trait or the alleles. E.g height; tall is T, short is t. these are the alleles that could make up the height.

A genotype refers to the genetic characteristics of an organism. A phenotype refers to the physical characteristics. For example, having blue eyes (an autosomal recessive trait) is a phenotype; lacking the gene for brown eyes is a genotype.

Conduct online research on the classes of soil remediation: in-situ and ex-situ. Briefly describe your findings.

Answers

Answer:

(Answers may vary.)

There are two classes of soil remediation: in-situ and ex-situ.

In in-situ remediation, there is no excavation of the contaminated soil. This remediation is an economical way of cleaning up. However, it takes a long time for the treatment to be effective. In addition, the treatment is not uniform because of variability within soil and difficulty in monitoring remediation progress.

Ex-situ remediation involves excavating a contaminated area. In this method, the soil is either treated on the same site or transported to a remote site for cleaning. This type of remediation is complex and expensive, but very effective. It involves the following:

homogenization of the contaminated soil before treatment

monitoring to ensure that the soil is cleaned to the required level

Explanation:

Soil remediation is the process of making the soil pure and free of contamination which affect the health of the soil and the organisms  that depend on it for their survival.

The two classes of soil remediation are:

In-situEx-situ

In-situ has to do with the treatment of the soil by removing the affected soil so that other parts of the soil does not get contaminated.

Ex-situ method is the process which involves taking the affected soil to an external site for decontamination which ensures that the other parts are not affected.

Question 1:
C. Nervous

BECAUSE
— We can eliminate A because we aren’t using the endocrine system (hormones).
— We can eliminate B because we aren’t using the integumentary system (skin, hair).
— We can eliminate D because the respiratory doesn’t instruct any systems, it just keeps them going.

Question 2:
D. Immune, Integumentary, Circulatory

BECAUSE
— We can eliminate A because we aren’t using the endocrine system (hormones).
— We can eliminate C because we aren’t using the muscular system (muscles).
— We can eliminate B because we aren’t using the skeletal system (bones).

Question 3:
D. None of these

BECAUSE
— We can eliminate A and C because we need the integumentary system to maintain body temperature (the integumentary system uses skin to regulate body temperature).
— We can eliminate B because we need the muscular system to maintain body temperature (the muscular system uses its ability to contract muscles to create heat).

Question 4:
B. Digestive, Circulatory, Excretory

BECAUSE
— We can eliminate A and C because we need the excretory system to digest and maintain homeostasis (to prevent damage to the body).
— We can eliminate D because B is our answer.

Question 5:
B. Reproductive, Nervous, Endocrine, Circulatory

BECAUSE
— We can immediately eliminate A, C, and D because we need the excretory system (hormones) to reproduce.

Why are recessive traits shown less than dominant traits?

Answers

Answer:

Dominant traits are always expressed when the connected allele is dominant, even if only one copy of the dominant trait exists. Recessive traits are expressed only if both the connected alleles are recessive. Recessive traits are found in fewer individuals as it can only be expressed in hom.ozygous condition. In a monohybrid cross between heterozygotes there is only 25% chance of recessive trait being expressed and 75% chance of dominant trait being expressed. Therefore in a population dominant trait is more apparent.
