In what way is DNA replicated
Answer: DNA replication occurs in two steps.. first, a so-called initiator protein unwinds a short stretch of the DNA double helix. Then, a protein known as helicase attaches to and breaks apart the hydrogen bonds between the bases on the DNA strands, thereby pulling apart the two strands.

A human body with endocrine glands are shown. The glands on the kidneys are indicated by the arrow.
Answer:
its the adrenal gland B on ENG 2022
Explanation:
The glands on the kidneys are indicated by the arrow, and the gland is called the adrenal gland which is present in the second option, and there are two adrenal glands on the two kidneys of the human body.
What is the importance of the adrenal glands in humans?The adrenal glands are two small glands located on top of the two kidneys that play an important role in the endocrine system because they produce hormones that help regulate a variety of important functions, such as metabolism, immune system function, and the stress response by releasing hormones like adrenaline, cortisol, and epinephrine, etc, while adrenaline, is released in response to stress or danger, it increases heart rate, blood pressure, and glucose levels, preparing the body for stress.
Hence, the glands on the kidneys are indicated by the arrow, and the gland is called the adrenal gland, which is present in the second option, and there are two adrenal glands on the two kidneys of the human body.

" Today, we push economies to grow whether or not they make us thrive. Especially in the richest countries, we should strive for economies that make us thrive whether or not they grow" what type of economic model does this statement represent
Answer:
the doughnut
Explanation:
The new economic theory by the English economist Kate Raworth, called Doughnut Economics, emphasizes the need for a prosperous and sustainable economy to balance the quality of life and environment. She stated that today that economists are deluded by a focus on expanding GDP at the expense of other crucial aspects that build a prospering, inclusive economy. She argues that the economic goal should be to meet the needs of everyone within the resources of the world and appeals to a need for economic mechanisms that will boost the economy with an adequate balance of social and environmental needs.

Answer:
Your answer would be Phospholipids
Explanation:
The phospholipid bilayer that makes up the plasma membrane has hydrophobic tails and polar heads that face each other to repel water.
What is a plasma membrane?The membrane that divides the inside of the cell from the external environment is known as the plasma membrane, sometimes known as the cell membrane, and it is present in all cells.
A cell wall is affixed to the plasma membrane on the outside of both bacterial and plant cells. The plasma membrane is made up of lipids and proteins, much like every other cellular membrane.
Therefore, the phospholipid bilayer, which creates a permanent barrier between two aqueous compartments, is the membrane's basic structural component.

surface runoff
subsurface runoff
groundwater runoff
groundwater discharge
ground water returns back to land
falling rainwater that gets absorbed into the soil
falling rainwater that flows over the ground
water that percolates into the aquifer
Answer:
Explanation:
Surface runoff: falling rainwater that flows over the ground.
Subsurface runoff: the water that infiltrates in the vadose zone; an example is falling rainwater that gets absorbed into the soil
Groundwater runoff: describes water pulled by gravity across land's surface, replenishing groundwater and surface water as it percolates into an aquifer.
Groundwater discharge: this describes movement of groundwater from the subsurface to the surface i.e. ground water returns back to land.
ground water returns back to land - groundwater discharge
falling rainwater that gets absorbed into the soil - subsurface runoff
falling rainwater that flows over the ground - surface runoff
water that percolates into the aquifer - groundwater runoff

DNA and molecular evidences are the additional evidences to support Darwin's theory. The correct option is B.
What is Darwin's theory?According to Darwin's theory, all species of organisms emerge and develop through natural selection of slight, inherited variations that significantly raise the individual's capacity to compete, stay alive, and reproduce.
It is backed up by research from a wide range of scientific disciplines, as well as genetics, which shows that DNA from different species is similar.
Fossils, embryological studies, anatomical and morphological characteristics, and molecular biology are examples of evidence that support the theory of evolution by comparing DNA sequences.
Thus, the correct option is B.

Bacteria with the ability to break down certain types of plastic are placed with a colony of E. coli bacteria that lack this ability. Plasmid transfer occurs between the two colonies of bacteria and some of the E. coli gain the ability to break down plastic as well. What inference can be drawn about the nature of plasmids from this observation? A. Plasmids are carbohydrates which provide structural support. B. Plasmids are lipids which provide energy for the cell. C. Plasmids are proteins which build tissues. D. Plasmids are nucleic acids which can pass on traits
Answer:
D. Plasmids are nucleic acids which can pass on traits
Explanation:
A Nucleic acid is one of the four biomolecule polymers in living systems. It is made up of monomeric units called Nucleotides. RNA and DNA are the two nucleic acids in existence and they function in storage and expression of genetic information.
According to the question, a colony of bacteria that can break plastics were mixed with the colony that can't break plastics. The two different colonies engage plamids, which conferred the ability to break plastics to some of the colonies that previously couldn't. This tells us that the ability to break plastics in the certain bacteria colony is GENETIC.
If the trait is genetic, the plasmid must be a nucleic acid because of the ability to genetically pass on traits. Note that, a plasmid is an extra-chromosomal DNA (nucleic acid) capable of replicating on its own. Hence, plasmids are nucleic acids which can pass on traits.

What does Saccharomyces cerevisiae (Baker’s yeast) need to survive?
Answer:
Food (Sugars)
Explanation:
S. cerevisiae feeds on sugars for energy, in the process producing carbon dioxide and alcohol (this is fermentation in a nutshell). The carbon dioxide bubbles get trapped in the dough, creating the lift that makes the dough rise. The alcohol, meanwhile, evaporates when baking, transforming into gas that also contributes to the rise of the bread. The alcohol, along with acids produced during the fermentation process, impart that wonderful flavor and aroma associated with yeast-leavened breads.

Mendel’s pea plants had either purple or white flowers. This means that the plants can self-pollinate. have two recessive traits. have two alleles for the gene. have two copies of a gene from one parent.
Answer:
I think it's that they have two alleles for the gene
The statement that Mendel’s pea plants had either purple or white flowers means that the plants have two alleles for the gene.
MENDEL'S LAW:Gregor Mendel is regarded as the Father of genetics due to his immense contribution to knowledge of genetic inheritance.
According to Gregor Mendel, a gene consists of two alleles, which individually encode different phenotypes of a particular trait.
In this question involving flower color gene, two alleles coding for purple (P) and white color (p) are present in the gene.

B. Vascular seedless, Non
vascular, Angiosperm,
Gymnosperm
C. Non vascular, Vascular
seedless, Gymnosperm,
Angiosperm
D. Angiosperm, Gymnosperm,
Vascular seedless, Non vascular
Answer:
The correct order of evolution is C- Non Vascular, Vascular seedless, Gymnosperms, Angiosperms.
Explanation:
The first plants to evolve were the non-vascular bryophytes like fungi and algae.
The next to evolve were vascular plants that supported a vascular tissue system but lacked seeds.
Gymnosperms are vascular plants that have seeds.
The seeds produced in the gymnosperms could undergo fertilization easily as the wind acted as pollen carrier.
The next to evolve were angiosperms or flowering plants.
Flowering plants have highly modified shoots that carry male as well as female gametes.
