information presented in the passage?
It shows exactly how many synapses a person's
brain has at birth
Speech, emotional regulation, movement, and
vision-all of these extraordinary abilities and
many more are possible thanks to the organ
that serves as the body's control center. When
one thinks of "brain power, it is the faces of
adult inventors, professors, and novelists that
Ekely come to mind. Remarkably the most
critical time period with respect to brain
development occurs relatively soon after an
individual is bom.
A newborn enters the world as a fairly helpless
creature, but her brain hos billions upon

It gives more information than the passage by
showing that the number of synapses returns to
what it was at birth.
It provides specific information about how many
synaptic connections are formed in each year of a
person's life.
It gives information about synaptic connections

Answer:
50%
Explanation:
Based on this chart, the approximate percentage of the total items that result from the action of people is 70% - 80%.
What is a pie chart?A pie chart can show the method by which a total amount can be divided between the levels of a categorical variable as a circle is divided into radial slices.
Each categorical value is corresponding to a single slice of the circle, and the size of each slice, both in the area and arc length, is indicative of the proportion of the whole that each category level will take.
Pie charts have comparatively limited cases of use this is encapsulated particularly accurately according to its definition.
So, for the utilization of a pie chart, one must have some kind of a whole amount that is divided into a number of distinct parts. These are represented by various sections.
Therefore, based on this chart, the approximate percentage of the total items that result from the action of people is 70% - 80%.

Describe the situations in which a normal human cell would enter the cell cycle and undergo mitotic cell division. Explain how spindle fibers help ensure the products of mitosis are two identical cells with a full set of chromosomes.
Answer: An example of a specific case is when a skin lesion occurs. Through mitosis, new skin cells are generated to repair damaged tissue. These cells have to be genetically identical to each other. The spindle fibers are structures formed by microtubules extending from one pole to another to orient the duplicated chromosomes in the spindle, bringing them to the position they occupy during metaphase.
Explanation:
Mitosis is a process of cell division that occurs in eukaryotic cells, i.e. cells that have a nucleus where their genetic material is located. This process generates two identical cells with the same DNA, that is, with two identical nuclei, so it does not provide genetic variability except in case of specific mutations. The objective of mitosis is cell multiplication while preserving genetic information. But in general, in mitosis there is an equal distribution of the cell nucleus as well as the rest of the cell content.
The phases of mitosis are as follows:
Interface: The cell duplicates its organelles and its DNA to have twice everything before division.Prophase: The nuclear membrane breaks, the chromosomes condense, the centrosome duplicates and migrates to the opposite poles of the cell forming microtubules. Also, fibers of the mitotic spindle are formed. Prometaphase: The microtubules invade the space where the genetic material is.Metaphase: The replicated chromosomes line up in the middle of the cell, called the equatorial plane.Anaphase: Microtubules separate chromosomes towards the opposite poles. Telophase: The nuclear envelope is re-formed from the remaining fragments of the original.Cytokinesis: A cleavage groove is created in the common cytoplasm of the two new cells where the chromosomes were aligned. The cytoplasm is thus strangled until the membrane allows total separation.Mitosis is then a cellular process that occurs in multicellular organisms to repair damaged tissue, or for growth or development. An example of a specific case is when a skin lesion occurs. When a person suffers an injury, many reactions take place in the repair process to repair the damage including inflammatory, proliferative, and remodeling phases. Through mitosis, new skin cells are generated to repair damaged tissue. These cells have to be genetically identical to each other, to have the same genetic fingerprint and the same function.
The spindle fibers are structures formed by microtubules extending from one pole to another. The kinetochore microtubules attach to the kinetochore, a structure that forms at the centromere of each duplicated chromosome, and orient the duplicated chromosomes in the spindle, bringing them to the position they occupy during metaphase and attracting the newly separated chromosomes to the poles during anaphase.
Spindle fibers has a great contribution in the process of mitosis.
The spindle fibers help to ensure the products of mitosis which is two identical cells with a full set of chromosomes due to attracting the chromosomes towards the poles. Spindle fibers move chromosomes during cell division by attaching to chromosome arms and centromeres and drag the chromosomes towards the pole.
This movement of chromosomes leads to the formation of one parent cell into two daughter cells having equal and same set of chromosomes so we can conclude that spindle fibers has a great contribution in the process of mitosis.

Explain what is ecological conservation and conservation of the environment. What can you do to conserve the environment? Why do you think it is important to conserve the environment.
WILL NAME BRAINLIST!
Answer:
Conservation ecology is the branch of ecology and evolutionary biology that deals with the preservation and management of biodiversity and natural resources. Its goal is to find ways to conserve species, habitats, landscapes, and ecosystems as quickly, as efficiently, and as economically as possible.
-These are some examples of how we can conserve the environment:
Recycle your rubbish and participate in or help organize recycling campaigns.
Avoid littering and participate in or help organize litter clean-ups (here you can link to a website for volunteering or starting your own beach clean-up).
Use less plastic by, for example, carrying a reusable water bottle, saying no to disposable straws and cutlery, avoiding plastic toys, and bringing your own shopping bags (for further ideas on a plastic-free life take a look here).
Swap toys, movies, and books instead of buying new ones.
Donate, recycle, and repair electronic devices (see how here).
Use less water when brushing teeth, taking a shower, or washing the dishes.
Use less electricity by turning off lights and electronic devices when not in use, using energy-saving light bulbs, and hanging clothes to dry.
Use public transport, share a journey with friends (e.g., car-sharing), cycle, or walk when possible.
Use less paper by not printing unnecessary things and reading e-books.
Turn down the air conditioning when it is hot and use fans if you are still hot-they use much less power.
Turn down the heat when it is cold and use sweaters, blankets, and socks to keep warm.
Do not waste food and try to buy food that is grown locally and in season.

What is an obligate anaerobe? How do obligate anaerobe like Bacteria C get energy?
Answer:
What is an obligate anaerobe?: An organism, such as a bacterium, that can live only in the absence of oxygen.
How do obligate anaerobe like Bacteria C get energy?: Obligate anaerobes metabolise energy by anaerobic respiration or fermentation. In aerobic respiration, the pyruvate generated from glycolysis is converted to acetyl-CoA. This is then broken down via the TCA cycle and electron transport chain.
