5-Which of the following orientations of phospholipids best represents the
phospholipid bilayer of the plasma membrane? Explain your choice
A.
B.
C.
D.
Answers
Answer:
A
Explanation:
Option A is the orientation of phospholipids that best represents the phospholipid bilayer of the plasma membrane.
The phospholipid bilayer (the lipid layer) is known to be a thin polar membrane. It is usually made of two layers of molecules that are lipids. These are flat sheets which actually form a continuous barrier around the cells.
The phospholipid is a lipid which is made up of glycerol, two fatty tails and the head is phosphate-linked. The tails point inward and are arranged in a way called phospholipid bilayer.
Phospholipids are great for building the protective barrier around the cell of the body.

What is complimentary DNA?Humans and nearly all other species carry their genetic information in DNA, also known as deoxyribonucleic acid. The DNA of an individual can be found in almost all of their cells.
The information molecule is DNA. It contains information needed to create proteins, which are other big molecules.
These instructions are dispersed throughout 46 lengthy structures called chromosomes that are found inside each of your cells. Numerous smaller pieces of DNA, known as genes, make up these chromosomes.
Complementary sequence is a sequence of bases in a nucleic acid that can be combined to generate a double-stranded structure.
For instance, G-T-A-C is the complementary sequence to C-A-T-G, where each letter represents for a different DNA nucleotide.
The DNA sequence can be:
DNA molecule 1: TACCGGATGCCAGATCAAATC, complimentary will be ATGGCCTACGGTCTAGTTTAG.DNA molecule 2: TACGGGGGCGTAACCACAACT, complimentary will be ATGCCCCCGCATTGGTGTTGA.DNA molecule 3: TACCTGTTAAGCTACAAAATT, complimentary will be ATGGACAATTCGATGTTTTAA.Thus, this is the complete match for the given scenario.

While walking through a rainforest, a zoologist spots a colorful organism growing on a dead tree stump. Further examination reveals this organism is a
multicellular organism, possesses a nucleus, and has cell walls but no chloroplasts. The zoologist would most likely place this organism into which kingdom?
O A Plantae
OB. Decomposers
C. Prokaryotes
OD. Fungi
Answers
Answer:
D:fungi
Explanation:
The zoologist would most likely place this organism into Fungi kingdom. The correct option is D.
What is kingdom Fungi?Any member of the eukaryotic group of organisms, which also includes the more well-known mushrooms and microbes like yeast and mould, is referred to as a fungus.
Eukaryotic creatures known as fungi include yeasts, moulds, and mushrooms as well as other microbes.
These organisms fall under the category of fungus. The creatures that make up the Kingdom Fungi are pervasive and have a cell wall.
As a biologist notices a vibrant organism sprouting on a stump from a dead tree.
A closer look reveals that this organism is multicellular, contains a nucleus, cell walls, but no chloroplasts. He probably would have put this organism in the kingdom of fungi.
As prokaryotes and decomposers are not having the characters given by the zoologist and plant also possesses chloroplast, so it can come under Fungi Kingdom.
Thus, the correct option is D.

you answer this questions
Answers
Some of the key elements of Mendel’s original model were:
Heritable traits are determined by heritable factors, now called genes. Genes come in pairs (that is, are present in two copies in an organism).
Genes come in different versions, now called alleles. When an organism has two different alleles of a gene, one (the dominant allele) will hide the presence of the other (the recessive allele) and determine appearance.
During gamete production, each egg or sperm cell receives just one of the two gene copies present in the organism, and the copy allocated to each gamete is random (law of segregation).
Genes for different traits are inherited independently of one another (law of independent assortment).

E)
The mRNA is exported from the cell through the membrane.
Answers
Answer:
C) The mRNA contains a start codon that reads AUG.
D) The mRNA travels from the nucleus to the ribosome.
Explanation:
mRNA is single stranded. The mRNA does leave the nucleus but does not leave the cell. The mRNA does not carry the amino acids, that job belongs to the tRNA and it brings them to the ribosome.
The formation of the mRNA from the DNA is called transcription. In this process, the mRNA has both the introns and the exons.
The correct option of the following question is D
The replication, transcription all process is occurs in the cytoplasm of the cell. After the process of replication, the DNA moves to the nucleus for the transcription process. The process of the formation of protein from the mRNA is called translation. The translation process occurs in the ribosomes.
The protein formation requires the ribosomes hence the RNA must be transferred to the ribosomes.
Hence, the correct option is D that is the mRNA travels from the nucleus to the ribosome.

A student drew the following diagram to model the structure of a prairie
community. Which level represents short and tall grasses?
A. Level 2
B. Level 1
C. Level 4
D. Level 3
Answers
Answer: B. Level 1
Explanation:
The prairie community is dominated by the grass and vegetation cover. Thus the lower most trophic level in the prairie ecosystem are the short and tall grasses. They produce major source of biomass for the herbivores of the food chain. They consume the grasses can be designated as primary consumers of the food chain. Also the producers which are grasses which make up the large amount of biomass will provide a source of food for the consumers. They will receive 100 percent energy from the sun and they will utilize 90 percent of it to make their food by the process of photosynthesis. Only ten percent of energy is transferred to the next trophic level.

Large leaf size
Small seed size
Small Stem
Large root size
Answers
Answer:
The picture was NOT a part of that question. The correct answer is Large leaf size. A
Explanation:
Leafs trap sunlight to perform photosynthesis for chemical energy which takes place in the chloroplast.
Photosynthesis is the process by which plants convert light energy into chemical energy. Plants can trap more sunlight if the size of leaves is large. Thus, the correct option is A.
What is Photosynthesis?Photosynthesis is the process by which plants synthesize their food in the form of carbohydrates (sugars). This process takes place in the chloroplast of cell. It contains chlorophyll pigment. This pigment is responsible for trapping sunlight.
There are more chloroplast present on the leaf surface than other parts of cell. This organelle is responsible for the synthesis of carbohydrates in plants as they trap sunlight which is converted into chemical energy. The more the number of chloroplast in the cell, more will be the rate of photosynthesis in plants.
Therefore, the correct option is A.

What is a nucleus and its functions?It is a double-membrane-bound cell organelle found only in the eukaryotes, which comprises the genetic material. The prime function of the nucleus is to monitor a cell's reproduction and growth. It does not only store DNA, it also performs various essential cellular procedures.
The duplication of the DNA, that is, DNA replication takes place within the nucleus of the cell. It comprises the instructions for producing two identical copies of the cell, and each cell produced will get its own set of instructions. It is also the site for the process of transcription.
Thus, the nucleus is the structure that comprises the instructions for producing a copy of the cell.

When a new viral infection appears in a population,scientists usually try to develop a vaccine against the virus. Which substances would most likely be contained in the new vaccin
Answers
Answer:
Antigen, stabilizers, surfactants, diluents, preservatives
Explanation:
Antigen: This is part of the protein structure virus or part of its genetic material. These parts are active. But sometimes, the inactivated form of the virus is also included in the vaccine. Stabilizers: Avoid other chemical reactions occurring in the interior of the vaccine. Surfactants: They prevent the occurrence of sedimentation and agglutination of the elements inside the vaccine. Diluent: Used to dilute the vaccine in an appropriate concentration before being used. Preservatives: As the word says, preservatives avoid any possible contamination of the vaccine. These elements´ use depends on the doses prepared. If it is only for one-person use, then they are not needed. But if the doses are to be used by more than one person, they need preservatives because once the vaccine is opened it is vulnerable to contamination.
