Explanation:
We need to recycle our waste because Earth is a closed system with respect to
matter, and new matter does not enter the environment. Agree or disagree
I disagree because although recycling is good, Earth firstly is not a closed system and new matter enters the environment all the time, such as comets.
In terms of matter, the Earth is often referred to as a closed system. In other words, the total amount of matter on Earth neither changes nor becomes more or less; Instead, it can take on different forms due to different processes. So, I am agree with this statement.
Although the Sun provides the world with continuous energy, most of the actual matter on Earth is recycled and used in various cycles. Recycling of waste is important because it enables us to recover useful materials and resources, reducing the need for mining new raw materials from the earth. Recycling helps us to reduce the environmental damage caused by the extraction and disposal of waste as well as the depletion of natural resources. It helps maintain long-term equilibrium inside a closed system of matter on Earth.

is the DNA in the form of chromatin or chromosomes when a cell finished cytokinesis
Answer:
Cell cycle consists of interphase and mitosis. During interphase there are 3 phases- G1, S and G2 phases. G1 is the resting phase after previous mitotic phase, S phase is DNA synthesis phase and G2 phase is again resting phase.
DNA synthesis occurs before mitotic phase which is the actual cell division phase and chromosomes are condensed during mitotic phase therefore it's in the chromatin form that DNA is synthesised.

A red flower RR and a purple flower BR have 4 offspring how many will be red blue and purple? Complete a Punnett square
Answer:
So three of the offspring will be red, blue and purple and one will be purple.
hope that's correct and it helps
This question is in accordance with the mendel law of independent assortment which stated that two alleles assort independently during gamete formation. Therefore, the resultant punnett square will show flower having the genotype of RB and purple color as its phenotype. See Attachment for punnet square results.

Phenomenon: Miss Westbrook visited family in Aspen last spring. Aspen is in Colorado and has an elevation of 8,000-9,000 feet. The Bay Area has an elevation of 0-100 feet. Miss Westbrook’s breathing and heart rate both sped up every time she went hiking or skiing in Aspen. Why do you think this happened?
Hint: Your brain regulates the rate and depth of your breathing to match the needs of your body for 02 intake and CO2 removal.
Breathing rate refers to the number of breaths per minute.
This happened due to the low air pressure in the highest areas of Colorado, which made hard the intake of air.
Air pressure is fewer as the elevation in an area increases. In other words, the air over us is less, so the pressure that it makes is lower.
Miss Westbrook's heart rate and breathing sped up due to the low air pressure that she experimented with when ascending or when skiing in Aspen, which is very elevated. As the pressure is lower, not much air can enter the lungs, so her brain increases the breath rate to obtain the same amount of oxygen that her body had when breathing normally on the Bay. As there is not enough oxygen in her body, the brain also increases the heart rate to match the rhythm of the breath and deliver the scarce oxygen to the different parts of the body.
In conclusion, the increase in the heart and breath rate happens due to the low air pressure in elevated areas that makes our body find ways to compensate for the decrease in the amount of oxygen that our body can take.

Answer:
Answer below
Explanation:
Cholesterol refers to a group of chemical compounds. A sterol is a kind of lipid, and cholesterol is one of them. All animal cells produce cholesterol, which is an important structural component of cell membranes. It is a yellowish crystalline solid when chemically separated.
a sterol-type molecule present in most human tissues. Cholesterol and its derivatives are key components of cell membranes and precursors of other steroid chemicals, but a high proportion of low-density lipoprotein in the blood (which delivers cholesterol to the tissues) is linked to a higher risk of coronary heart disease.
Cholesterol is a waxy, fat-like molecule found in all of your body's cells. Cholesterol is required by your body for the production of hormones, vitamin D, and chemicals that aid digestion. Your body produces all of the cholesterol you require.

The concentration of lactic acid in the student's
muscle tissue was most likely greatest during trial
A) A В) В
C) C D) D
Option D has the highest concentration of lactic acid in the student's muscle tissue.
We can arrive at this answer because:
Lactic acid increases its concentrations in the muscle due to a high physical effort in anaerobic conditions.This promotes a lack of oxygenation in the muscle, which through contractions, causes the cell to partially catabolize glucose molecules.The result of this is the creation of two pyruvic acid molecules, which will react with NADH2 molecules, creating lactic acid, which will build up in the muscle as the exercise continues.As we can see in the information presented above, option D shows the performance of flexions with more intensity and for a longer period, which justifies a greater accumulation of lactic acid in the muscle.
It is important to remember that the accumulation of lactic acid in the muscle is a negative situation and that it can cause muscle pain and fatigue.

The roller coaster is your favorite ride! but the line is always long! having just studied potential and kinetic energy in physics, you evaluate the energy changes of the cars as they move on the tracks. Compare the potential energy of the cars if they are stopped at points A to point D.
A. Neither have potential energy.
B. The potential energy is the same.
C. Potential energy is greatest at point D.
D. Potential energy is greatest at point A.
Potential energy is greatest at point D. Therefore, option C is correct.
What is potential energy?Potential energy is the energy that is stored inside of an object due to the object's position, state, or arrangement. When an object's position, status, or configuration changes, the energy that has been stored in it is released.
The gravitational potential energy of an item, the elastic potential energy of a stretched spring, and the electric potential energy of an electric charge in an electric field are examples of common types of potential energy.
Potential energy depends upon the mass and height of the object. The greater the mass and height, the greater will be the potential energy of the object. The height of position D is maximum, therefore potential energy is greatest at point D. Hence, option C is correct.
