Chloroplasts are the organelles in plant cells that convert solar energy to chemical energy (sugars) that can be used by the cell. Mitochondria are organelles in all eukaryotic cells that convert sugars to ATP Both organelles are have double membranes and contain their own set of DNA. What is the likely explanation for this?
The chloroplasts and mitochondria are known as the membrane bound organelles.
Membrane bound organellesThe cells of living organism contain membrane bound organelles which are surrounded by their lipid bilayer and they contain their own set of DNA.
Example of membrane bound organelles are:
Chloroplasts: This organelle contains chlorophyll which convert solar energy to chemical energy (sugars) that can be used by the cell during photosynthesis.This is found only in plants which are producers.
Mitochondria: This organelle is found in animal cells which are used to convert sugars to ATP.Therefore, the chloroplasts and mitochondria are known as the membrane bound organelles.

If the pores in the dialysis tubing were too small to allow iodine potassium to pass through, would the liquid in the tubing turn black?
Yes or no?
Based on selective permeability, if the pores in the dialysis tubing were too small to allow iodine potassium to pass through, the liquid in the tubing would not turn black.
What is Selective permeabilitySelective permeability refers to the ability of a membrane to allow some molecules to pass through it but no others.
In the dialysis tubing, selective permeability is used to remove some substances but not others.
The selective permeability of the dialysis tubing depends on the pore size.
When a dialysis tubing containing starch solution was dipped into a beaker containing iodine, the solution in the tubing turned black due to the ability of iodine molecules to pass through the membrane.
However, if the pores in the dialysis tubing were too small to allow iodine potassium to pass through, the liquid in the tubing would not turn black.

Which of following has the least ecological tolerance to climate change?
- Small island close to the mainland
- Small island far away from the mainland
- Large island close to the mainland
- Large island far away from the mainland
Given what we know, we can confirm that a small island far away from the mainland is the least tolerant to climate change.
Why is this the case?A small island far away from the mainland is less tolerant of climate change from an ecological viewpoint than the other options listed. This is the case because of the size and location of the lsland. A small faraway island does not have many options for the wildlife to migrate or adapt and is therefore more intensely affected by any changes in climate.
Therefore, we can confirm that a small island far away from the mainland is the least tolerant to climate change.

Why do we wear black or dark coloured clothes in winter?
Answer:
Why do we wear white or light coloured clothes in summer?
We wear white or light coloured clothes in summer because white coloured clothes reflect most of the sun's heat and absorb very little of the sun's heat and keeps our body cool.Why do we wear black or dark coloured clothes in winter?
We wear black or dark coloured clothes in winter because black coloured clothes absorb most of the sun's heat and keep our body warm.Explanation:
[tex] \blue{ \boxed{ \frak{BrainlyFairy}}}[/tex]
[tex]\bold{\huge{\orange{\underline{ Answers }}}}[/tex]
Answer 1 :-In summer we generally prefer white or light coloured clothes because :-
Light or white coloured clothes are bad absorber or a good reflector of heat . So when light rays falls on any white or light coloured clothes. they reflect that rays and absorb negligible of it . Light or white coloured clothes also allow the heat to escape from your body which makes you feel cool for a long day . Light or white coloured clothes are also act as a good absorber of sweat so when people sweat .Then as a good absorber , they absorbs it and you will feel coolAnswer 2 :-In winter we generally prefer dark or black coloured clothes because :-
Black or dark coloured clothes are good absorber and bad reflector of heat. When light rays falls on any black or dark coloured clothes it absorbs all the heat especially black coloured clothes. This happens because different colours have different wavelength. On the other hand, black colour has the ability to absorb all different types of wavelength of visible colour that is why it act as good absorber. The black or dark coloured clothes absorb all the heat and allow negligible heat to escape and due to this our body feels warm It is also act as good soaker of sweat just like white coloured clothes.Name the part of a seed which allows water and air in to seed

What are marine algal blooms, red tides, and dead zones? How might biological magnification play be part in human illness?
Answer:
Cyanobacteria, a type of photosynthetic bacteria also known as blue-green algae, are often the cause of algal blooms in freshwater and occasionally in marine water. ... Cyanobacteria HABs produce multiple toxins, including liver, nerve, and skin toxins, which can affect human and animal health.
Many red tides produce toxic chemicals that can affect both marine organisms and humans. The Florida red tide organism, K. brevis, produces brevetoxins that can affect the central nervous system of fish and other vertebrates, causing these animals to die.

comprehensive understanding of an individual's development.
We can conclude that, Barbie's choices are egocentric which indicates her being in the preoperational stage of Piaget's theory of cognitive development.
People who use a biopsychosocial approach are most likely to gain a: comprehensive understanding of an individual's development.
What is the Preoperational Stage?
The preoperational stage is the second stage in Piaget's theory of cognitive development, which is characterized by:
EgocentrismSymbolic representationThe preoperational stage begins from 2 years of age up to 5 years of age. At this stage, children tend to use symbols to represent their own world.
According to Piaget, children tend to be egocentric during the preoperational stage, which explains why Chloe will get a gift like a Barbie doll for her dad. This shows Chloe, at this stage, cannot understand that her dad think in a different way she thinks.
Therefore, we can conclude that, Barbie's choices are egocentric which indicates her being in the preoperational stage of Piaget's theory of cognitive development.
What is the Biopsychosocial Approach?In psychology, the biopsychosocial approach is a wide approach that takes into consideration biological, social, and psychological factors, and how they interact to influence health care delivery, illness and health.
Therefore, people who use a biopsychosocial approach are most likely to gain a: comprehensive understanding of an individual's development.
