What is the function of the organelle labeled number 9 in the image above?
store genetic information
digest waste
produce energy
package and transport
Answer:
produce energy
Explanation:
The cell organelle labelled 9 can be identified as mitochondrion.
This mitochondrion, which is bounded by a double-membrane is popularly referred to as the "power house of the cell". It is usually found in most eukaryotic cells.
It is called "the power house" simply because it serves as the major site of the cell where energy in form of ATP is produced for the proper function of the cell. It is where most of the chemical energy supplies of the cell comes from.

Shahzadi is looking at a cell with an electron microscope. She estimates that the cell is 2 x 10-5 metres long. What is this number fully written
out?
The length of the cell when the number is fully written is twenty millionth meters long.
Given that the length of the cell is 2 x 10⁻⁵ meters long.
1 millionth = 0.000001 = 10⁻⁶
The length of the cell = 2 x 10⁻⁵ meters = 20 * 10⁻⁶ meters
Therefore the length of the cell when the number is fully written is twenty millionth meters long.

Cells have genes that affect cell division. These genes may be damaged by
environmental factors such as radiation, smoking, and viral infections. Oncogenes
stimulate rapid cell division and are normally turned off in adult organisms. Tumor
suppressor genes prevent continuous cell division and are normally turned on in
adult organisms. One of these tumor suppressor genes, called p53, can be turned off
by the effects of smoking tobacco. Based on the above information, what is the most likely result of turning off p53?
A Lungs become black from smoking
B Cells undergo uncontrolled division
C White blood cells are unable to stop infections
D. DNA chains are broken and form more chromosomes
Answer:
B.
Explanation:
A tumor is essentially when damaged cells continue multiplying. So by smoking your risking both damaging your cells and turning of the p53 gene.
can i have brainliest?
The most likely result of turning off p53 is cells undergo uncontrolled division. Hence option B is correct.
What are genes?Genes are defined as the fundamental genetic component transferred from parent to child. Genes are composed of DNA sequences and are organized sequentially at specified sites on chromosomes in the cell nucleus. The foundation of the body is made up of cells. Your body is made up of billions of interconnected cells in every part. Chromosomes are the units on which genes are organized.
Diseases like cancer can result from an alteration in the cell cycle's regular regulation. When the cell cycle is out of balance, cells have the potential to randomly divide and accumulate genetic errors that can cause a malignant tumor.
Thus, the most likely result of turning off p53 is cells undergo uncontrolled division. Hence option B is correct.

how come human populations differ from other animal populations
Answer:
Animal species come in many shapes and sizes, as do the individuals and populations that make up each species. To us, humans might seem to show particularly high levels of morphological variation, but perhaps this perception is simply based on enhanced recognition of individual conspecifics relative to individual heterospecifics. We here more objectively ask how humans compare to other animals ...
Explanation:
With in population, humans show low levels body height variation in comparison to variation observed in other animal population.
Similarly, human population does not show distinctive levels of body mass variation.
What are the importance of studying human population?The study of population helps us to understand the process that influence the size, growth, characteristics, and distribution.
Population studies highlight these problems for society, administrators, political System, economic Planning
The most important terminology which is immensely studied called demography where the study of human population is extremely essential to determine the age, composition.
It is essential to study in every country by analyzing patterns of life expectancy and accurately predict the future.
Demography is important to study, as it characterize the nature population changes over time, such as the aging population

How does the word mutualism relate to the world we live in? (biology)
A student performs an experiment to study the transport of water in and out of cells. He uses clear, semi-permeable plastic bags to represent the cell membrane. The student places three plastic bags of the same size, each containing a 1% concentration sucrose solution, into three different beakers. One beaker contains distilled water, another beaker contains a 3% concentration sucrose solution, and the third beaker contains a 1% concentratIon sucrose solution. The diagram shows the students experimental setup, the plastic bag before it is placed in the beakers, and the appearance of the bags after an hour in each solution. Which statement provides a conclusion about the transport of water in and out of cells based on the results of the students experiment?
Answer:
B
Explanation:
A. Water moves freely both inside and outside the cell independent of the solute concentration.
B. Water movement into the cell is dependent on the percent concentration of solutes both inside and outside the cell.
C. Water transports solutes out of the cell to balance the percent concentration of solutes both inside and outside the cell.
D. Water moves into the cell solutes move out of the cell to ensure their concentration is balanced both inside and outside the cell.
The correct statement that provides a conclusion about the transport of water in and out of the cells is that water movement into the cell is dependent on the percent concentration of solutes both inside and outside the cell.
Water molecules will always move from the region of higher water potential to the region of lower water potential. The more the solute concentration of a solution, the lower the water potential compared to a solution with a lower solute concentration.
Hence, water will move from the beaker containing distilled water into the plastic bag containing a 1% sucrose solution until an equilibrium is established - the solution in the beaker is hypotonic to the one in the bag.
On the contrary, water will move from the bag containing 1% sucrose solution into the beaker containing 3% sucrose solution until there is no longer any net movement of water - the solution in the beaker is hypertonic to the one in the bag.
There will not be any movement of water from the bag to the beaker containing 1% sucrose because both solutions are of the same concentration, that is, isotonic.
The correct option is B
How to treat Zygomycota desease?
Answer:
Zygomycota. It's a fungus and a disease that can be treated, usually, with azoles and echinocandins. You might also need medical debridement. It's part of the infected tissues while being guided by amphotericin B administration.

Covalent bonding can take place between atoms of the same element.
Answer: true
Explanation:
A covalent bond is the force of attraction that holds together two atoms that share a pair of valence electrons. Covalent bonds form only between atoms of nonmetals. The two atoms that are held together in a covalent bond may be atoms of the same element or different elements.
This question is incomplete because the options are missing. Here are the options:
A. True.
B. False.
A covalent bond occurs in two atoms when they join, to reach the "stable octet", and share electrons in the last orbit, forming a molecular orbital.
Covalent bonds are characterized by occurring
Between atoms of the same nonmetal element for example two or more atoms of carbon, nitrogen or argon bondedBetween different nonmetals, for example one atom of hydrogen bonded to one of carbon Between a nonmetal and hydrogen, for example one atom of hydrogen linked to one of nitrogenTherefore, the statement that a covalent bond can be formed between two equal elements is true.

The correct answer is A.
Explanation:
Correct on edge :)
**it wouldn't hurt to mark brainliest!!
Producing a litter of puppies by mating two dogs of different breeds using genetic engineering is an example of hybridization. Thus, the correct option is A.
What is hybridization?Hybridization is the process in which two complementary single-stranded DNA molecules or RNA molecules bond together with each other to form a double-stranded molecule of genetic material. The bonding is dependent on the appropriate base-pairing across the two single-stranded molecules of genetic material.
Interbreeding between individuals of different species within the same genus with favorable characteristics is called interspecific hybridization. For example, mule is produced from the cross between male donkey and female horse.
Therefore, the correct option is A.
