Answer:
Explanation:
because bacteria reproduce and make proteins very quickly , because the plasmids in bacteria also contain nucleotide sequences called restriction sites that can be cut easily by enzyme.
Explain why it makes sense to use the word translation to describe protein synthesis and why it would not make sense to use the word translation to describe mRNA synthesis?
Answer:
The application of the word translation makes sense at the time of describing the synthesis of protein as the language of nucleic acids is transformed into the language of polypeptides by the phenomenon of translation. On the other hand, it will not be suitable to describe the synthesis of mRNA using the word translation as the nature of the biomolecule stays similar because both the DNA and the product of DNA, that is, mRNA are nucleic acids.

Calculate the amount of energy you would expect to find at the secondary consumer level if there were 100,000 J of energy at the producer level in an ecosystem.
The amount of energy one would expect to find at the secondary consumer level if there were 100,000 J of energy at the producer level in an ecosystem is 1000J.
How to calculate amount of energy available in food chain?The food chain is a feeding relationship between living organisms in an ecosystem. Each organism occupies a position called trophic level.
The trophic levels involved in a food chain are as follows:
ProducerPrimary consumersSecondary consumersTertiary consumerThe producer begins the energy transfer, however, only 10% of the available energy is passed to the next trophic level because 90% of this energy is used for metabolic activities.
This means that if 100,000 J of energy is available at the producer level in an ecosystem, the following applies:
Primary consumers: 10/100 × 100,000 = 10000J of energy Secondary consumers: 10/100 × 10,000 = 1000J of energyTherefore, the amount of energy one would expect to find at the secondary consumer level if there were 100,000 J of energy at the producer level in an ecosystem is 1000J.

During G2 the Wee1 protein phosphorylates tyrosine-15 of the Cdc2 protein kinase, thus inactivating it. Only once dephosphorylation occurs and Cdc2 becomes active carn the cell pass from G2 into M and proceed to cell division. Can you think of a reason why the Wee1 protein was named as such?
Answer:
cells can't fully grow in Wee1 mutants
Explanation:
The G2 phase is a period where cell growth and proteins are synthesized to prepare for cell division. The Wee1 protein is a dosage-dependent inhibitor of mitosis. Moreover, the cyclin-dependent kinase 2 (cdc2) is a protein involved in the regulation of the cell cycle which phosphorylates serine residues in Wee1. However, in Wee1 mutants, Cdc2 is not inactivated (phosphorylated). This change causes cells to enter M phase prematurely, thereby producing "wee" mutant cells.

The correct listing of genetic terms from smallest to largest is nucleotide, gene, DNA molecule, chromosome.
GENETICS:
Genetics is the branch of biology that deals with the study of genes and inheritance. Like every subject, genetics possess some terms that can be hierarchically arranged. The terms are in the order:
Nucleotide: Nucleotide is the monomeric unit of nucleic acids made up of three components namely: nitrogenous bases, phosphate group and pentose sugar. Gene: A gene is a segment of DNA or RNA from an organism's genome that codes for a particular trait. DNA: DNA is one of the two nucleic acids that stores genetic information in living cells. Chromosome: Chromosome is a X-shaped structure made up of DNA and proteins tightly woven together.Hence, the correct listing of genetic terms from smallest to largest is nucleotide, gene, DNA molecule, chromosome.

Considering the drifting of continents, how do you explain the abundance of marsupials and the absence of native placental mammals in Australia
Answer:
this phenomenon is a natural consequence of evolutionary processes and continental drift
Explanation:
Marsupials are mammals in which newborn offspring are carried in a pouch of the female (mother) body. On the other hand, placentals are mammals that complete embryo development in the mother's body, in the placenta. All the extant marsupials are endemic to Australia and the Americas. It has been shown that marsupials diverged (evolved) in South America, Australia and Antarctica when these landmasses were joined. In Australia, marsupials evolved to fit an ecological niche, which can be attributed to geographic isolation due to continental drift, while placental mammals are relatively recent and more scarce (mainly bats and rodents) within this region.
what is the difference between bracketed key and indented key?
Answer:
Bracketed and indented keys are two dichotomous/or branching keys with an ordered, numbered couplet, and spatially differentiated respectively.
Explanation:
Dichotomous keys are used in the identification and classification of taxa.
Bracketed keys, or parallel keys, are easy to understand- for efficiency, these keep the first two entries of every couplet or pair being compared. It also makes use of a numbering system in the couplet choices for easy tracking.
Indented keys maintain an equal distance from the margin on the left of the pages. Successive couplets are indented til the taxon is identified.
When do land breezes develop? Which way does wind move during a land breeze?
Answer:
A low-pressure zone forms above the land surface from the rapid loss of heat. A high-pressure zone forms as the cooler land cools the air immediately above the surface. Winds aloft flow from the ocean to the land. Winds at the surface flow from high to low pressure, creating a land breeze

In man, glucose is present in blood plasma but not in urine. This is because glucose
molecules are
(A) actively transported from the proximal convoluted tubule to blood capillaries
(B) oxidised to supply energy for ultrafiltration
(C) stored in the kidney
(D) too large to enter Bowman's capsule
In man, glucose is present in blood plasma but not in urine. This is because glucose molecules are actively transported from the proximal convoluted tubule to the blood capillaries.
What is glucose?Glucose is a monosaccharide, biomolecule found in ingested food which is used to provide energy to the cells of the body. Glucose is usually found only in the blood, since it is reabsorbed in the renal tubules, but when there are pathologies in which glucose levels in the blood are increased, the sites that reabsorb glucose become saturated, thus having an escape of glucose in urine.
Therefore, we can confirm that in man, glucose is present in blood plasma but not in urine. This is because glucose molecules are actively transported from the proximal convoluted tubule to the blood capillaries.

Explanation:
There are 40 chromosomes in germ cells of a ferret. How many sex chromosomes are there in a ferret's ovum?
Answer:
Explanation:
In a mitotic cell division, the number of chromosomes remains constant. It is so because the chromosomes are replicated to produce chromatid which during cell division is equally distributed in all the daughter cells thereby preserving the chromosome number.Both sperm cell and ovum have 23 chromosomes each. It is the fusion of both at fertilization that brings about 46chromosomes seen in somatic cells. These chromosomes are 22pair somatic chromosomes and a pair of sex chromosome (I.e XX or XY).The cells of the body have a diploid number of chromosomes (2N). The diploid number is usually double the haploid number (1N), so if the haploid number of chromosomes is 20, then 2x20=40. So the answer either 40 or 36
To determine the number of sex chromosomes that are there in a ferret's ovum is 2 sex chromosomes.
Given the following data:
Number of chromosomes = 40 chromosomes.Sex chromosomes can be defined as a pair of chromosomes that are responsible for determining the gender of a living organism i.e whether an organism is either male or female.
To determine the number of sex chromosomes that are there in a ferret's ovum:
Mathematically, the number of chromosomes in an organism is given by the formula:
[tex]Chromosomes = 2N[/tex]
Where:
N is the number of sex chromosomes.Substituting the given parameter into the formula, we have;
[tex]40 =2N\\\\N=\frac{40}{2}[/tex]
N = 2 sex chromosomes
