Explain how brassinosteroids are synthesised, perceived and promote plant growth and development. Please give named examples and critical analysis to support your answer

Answers

Answer 1

Answer:

Brassinosteroids are synthesized from phytosterols and they promote plant growth and development by modulating cellular processes (e.g, cell division, elongation, photomorphogenesis, responses to environmental stimuli, etc).

Explanation:

Brassinosteroids are phytohormones similar to steroid hormones. Phytosterols include sitosterol, campesterol, and stigmasterol, i.e., lipid (cholesterol) molecules that form the cell membranes. These polyhydroxylated steroidal phytohormones play a wide range of cellular roles during plant growth, development and immunity. Examples of brassinosteroid functions include plant development, xylem differentiation, responses to biotic/abiotic stresses, reproduction, etc. For example, campesterol, which is a precursor of brassinosteroid hormones, is an integral membrane component that functions during plant embryogenesis by regulating the permeability of cell membranes and by altering membrane-associated proteins, as well as signal transduction pathways.

Which describes a difference between bivalves and cephalopods?
Bivalves use tube feet for movement, and cephalopods use muscular feet for movement.
Bivalves live only in ocean environments, and cephalopods live in a variety of aquatic environments.
O Bivalves use a radula to feed, and cephalopods use filter-like structures to feed.
O Bivalves have an open circulatory system, and cephalopods have a closed circulatory system.

Answers

Answer: D - Bivalves have an open circulatory system, cephalopods have a closed circulatory system

Explanation: I had to research the differences to find the answer

A difference between bivalves and cephalopods are bivalve animals use a radula to feed, and cephalopods use filter-like structures to feed, that is the third option, where they both belong to the Mollusca phylum.

What is the significance of bivalves and cephalopods?

Both bivalves and cephalopods belong to the mollusca phylum, and they are invertebrates, some of the bivalves, such as oysters and mussels, are important as they are a source of food for humans and as filter-feeding organisms; at the same time, squid and octopus are cephalopods. These organisms are significant in different fields of study, such as neuroscience and evolution.

Hence, a difference between bivalves and cephalopods are bivalve animals use a radula to feed, and cephalopods use filter-like structures to feed, that is the third option, where they both belong to the Mollusca phylum.

Describe how transposable elements create mutations within an organism and how transposable elements facilitate chromosomal rearrangements.

Answers

Answer:

Transposable elements are discrete segments of DNA that can be excised and reintegrated to another site in the genome, these can inactivate the gene in which they reside, cause chromosome breaks, and / or transpose to a new location within the genome.

Explanation:

Transposable elements are fragments of DNA that have the ability to jump from one part of the genome to another. While most of the DNA is always in the same place surrounded by the same neighboring pieces of DNA, mobile elements move from one place to another causing many changes or mutations. When a transposon moves through the genome, it can insert into a vital gene, disrupting its function, or into a location near vital genes, causing erroneous activation or inactivation.On the other hand, there can be chromosomal rearrangements due to transposons of the same family with complementary sequences that are separated in the genome and that by sequence homology match. This can lead to ectopic recombination. Large-scale rearrangements induced by mobile elements are considered a particular class of recombination events that influence genomic plasticity.

Answer: C:The arthropod is a crustacean because it has two body sections and an open circulatory system.

Explanation:

Crustacea are the arthropods. which includes the crabs, shrimp, barnacles, and others. These are the insects. These are the invertebrates. They have hard exoskeleton and segmented body forms. They are bilaterally symmetrical animals. They have four to six pairs of appendages which are jointed. Open circulatory system is present due to lack of developed blood vessels circulation.

The bacteria we are growing contain both chromosomal DNA and plasmid DNA. Both are circular, but they are different. In 3-5 sentences, discuss at least 3 differences between the chromosomal DNA and plasmid DNA found in our bacterial cells.

Answers

Answer:

Please find the explanation of the differences between chromosomal DNA and plasmid DNA below

Explanation:

As stated in this question, a bacteria cell contains both chromosomal or genomic DNA and an extra chromosomal DNA called PLASMID. They are both circular in shape but are different from one another in the following ways:

- Chromosomal DNA is larger in appearance than the plasmid DNA, hence, they differ in terms of size.

- Chromosomal DNA encodes all the information in the genome of the bacterial cell necessary for their growth and development while plasmid DNA encodes few additional beneficial characteristics such as antibiotic resistance, virulence etc.

- Chromosomal DNA is wrapped around histone proteins to form the chromosome structure but plasmid DNA is naked and not wrapped around histone proteins.

Which of the following factors most likely triggers arousal from hibernation?

A) the sun rising in the morning B)snow falling onto the ground
C) the environmental temperature dropping below 0 °C
D) a significant decrease in the animal's respiration rate

Answers

Answer:

A) the sun rising in the morning

Explanation:

In biology, hibernation refers to a physiological state where a plant or animal is metabolically inactive in the winter period (characterized by extreme cold). As far as the animal or plant is concerned, the cold weather during winter is an adverse condition, hence, they undergo hibernation in order to conserve their energy.

According to this question, arousal or wakening from hibernation would be triggered in the presence of heat source, which in this case is the SUN RISING IN THE MORNING.
