A human disease termed cardioencephalomyopathy results from a genetic change in the normal function of mitochondria. Babies who are born with the disease generally die from it. Scientists who study this disease using a bacterium known as Paracoccus denitrificans. Scientists were able to produce the same change in the bacterium’s genes that they found in the mitochondria of their human patients.
What is the BEST explanation for why scientists can use a bacterium to study this human disease?
A
Bacterial genes are very similar in structure to human genes.
B
Bacteria can be used as a model to study more complex cells.
C
The genes and chemical pathways found in bacteria are similar to those in human mitochondria.
D
The eukaryotic cells of humans share many characteristics with bacterial cells, including single stranded DNA.
The eukaryotic cells of humans share many characteristics with bacterial cells, including single stranded DNA. Thus option D is correct.
what is the structure of DNA ?DNA is referred as deoxy ribo nucleic acid, which is a nucleic acid, with a left handed double helical structure, are the basic unit of every living cell
It carry all genetic material responsible for expression of a character of an living organism; It is made up of nitrogenous base, sugar mainly pentose sugar and phosphate.
Nitrogenous base are purine and pyrimidine such as adenine, guanine, thiamine, cytosine; Adenine can pair with thiamine by two hydrogen bond where as cytosine can pair with guanine by three hydrogen bond.

Healthy ecosystems depend on–
Healthy ecosystems depend on a variety of factors working together in balance.
Some key factors include:
1. Biodiversity: Healthy ecosystems have a rich variety of species, including plants, animals, and microorganisms.
2. Nutrient Cycling: Ecosystems rely on the cycling of nutrients, such as carbon, nitrogen, and phosphorus, to support the growth and survival of organisms.
3. Energy Flow: Ecosystems depend on the flow of energy from the sun. Producers, such as plants and algae, convert solar energy into chemical energy through photosynthesis.
4. Interactions and Relationships: Healthy ecosystems are characterized by complex interactions and relationships among organisms.

A fire sits 72 feet from the abs of 125 foot tall building. Find the angle of Evel at ion from the fire to the top of the building
Answer:
60°
Explanation:
From the attachment,
Opposite side of the triangle= 125 feet
Adjacent=72 feet
Angle of elevation= (θ)
From trigonometry,
Tan (θ)= Opposite side /Adjacent adjacent
Where
(θ)=angle of elevation
If we substitute to above expresion we have
tan(θ)= 125/72
tan(θ)= 1.736
Tan^-1(1.736)=60°
θ= 60°
Hence, the angle of Evel at ion from the fire to the top of the building is 60°

why it is virtually impossible for a baby girl to be born with Norrie disease.
Answer:
The gene that has the wrong plan for the important growth factor in Norrie's Disease is on the X chromosome. If a girl (XX) has one X chromosome that does not work she will be protected from developing Norrie's Disease because she has a protective spare.
Explanation:
hope this helps!
Answer: Norrie disease almost entirely affects males.
Explanation: Due to the X-linked recessive pattern of inheritance, Norrie disease affects almost entirely males. Only in very rare cases, females have been diagnosed with Norrie disease; cases of symptomatic female carriers have been reported.

Infectious diseases have an easier time spreading now than they did several hundred years ago. What about society has changed that makes this possible? Describe at least TWO reasons.
Answer:
see below :)
Explanation:
Infectious are more easily spread nowadays becuse of an increased population. The more the population increases, the bigger the advantage an infectious disease has. As of right now, because everyone is wearing masks, their immune systems are being weakened. Another reason for this is because of the increase in chemicals in our foods, which are now being transferred to our bodies. All of the medications people are taking also have an affect on the spread of disease; it gives diseases a chance to mutate.

Some desert plants respond to darkness by opening their flowers at night to lure in pollinators. In
this situation, a plant's response system is working in conjunction with the —
immune system.
vascular system.
reproductive system.
root system.
Answer:
B
Explanation:
In this situation, a plant's response system is working in conjunction with the vascular system. Therefore, option B is correct.
What is a vascular system?The complex network of conducting tissues known as the plant vascular system connects all organs and carries water, nutrients, organic compounds, and different signaling molecules throughout the body of the plant. The primary transport systems of plants, xylem and phloem, make up vascular tissue. They often coexist in vascular bundles that cross the roots, stems, and leaves of all plant organs. Water and dissolved ions are moved upward through the plant through the xylem, starting at the roots.
Clubmosses, horsetails, ferns, gymnosperms (including conifers), and angiosperms are examples of vascular plants (flowering plants). The group is known by its scientific names, Tracheophyta, and Tracheobionta.

why do we need new body cells
Answer:
When we are adults many cells mature and become specialised for their particular job in the body. So they don't make copies of themselves (reproduce) so often. But some cells, such as skin cells or blood cells are dividing al the time. When cells become damaged or die the body makes new cells to replace them.

Needdd helllppp
Answer:
focusing on a single task is the best strategy for change
Explanation:
The career of Jacques Cousteau illustrates that focusing on a single task in life is the best strategy for the change in the social life of an individual as well as in the society. If a person performs many activities at the same time so its focus and concentration divides over the activities which is not more advantageous as compared to that person who focus on the single task until it is completed so focus on the single task in life is necessary for producing big change in life and in the society.

A protein channel in a hydrogen ion pump is shown below. What would happen if the concentration of H+ ions were higher inside the mitochondrion than outside the mitochondrion when the channel opened?
Answer:
The H+ ions moves outside.
Explanation:
The H+ ions moves outside the mitochondria of the cell if the concentration of H ions were higher inside the mitochondrion than outside environment of the mitochondrion in order to equalize the pH or H+ ions concentration of both inner side of mitochondria and outer side environment. This movement of H+ ions from a region of higher concentration to the region of lower through a semi-permeable membrane is known as osmosis which has a positive effect on the cell as well as organelles of the cell.

Use the student's hypothesis to predict which parachute, A, B or C, will hit the ground first. Give a reason for your answer?
Answer:
The heavier will come first to hit the ground.
Explanation:
That parachute will come faster and hit the ground first which has more weight than other parachutes because the heavier objects comes to the earth at faster rate as compared to light objects. So if all the three parachute has same size and shape but difference in weight than the heavier one comes to the ground first as compared to other two parachutes.
