Answers
Answer:
Chlorofluorocarbon.
Explanation:
Chlorofluorocarbon is the chemical compound that is responsible for the thinning of ozone layer present in the stratosphere. This Chlorofluorocarbon is used in the refrigerators and aerosol sprays. The major environmental consequence of the depletion of stratospheric ozone is the melting of glaciers in the Antarctica. It also has adverse effect on humans because it is responsible for the skin cancer disease in humans. Breathing ground-level ozone can trigger a variety of health problems such as chest pain, coughing, throat irritation, and congestion.

Explanation:
When a nerve impulse reaches the end of an axon, the axon releases chemicals called neurotransmitters. Neurotransmitters travel across the synapse between the axon and the dendrite of the next neuron. ... The binding allows the nerve impulse to travel through the receiving neuron.

What evolutionary feature will you expect to see in the tortoises on the island?
Answers
Answer: The most expectant evolutionary feature would be longer necks. This will enable the tortoises to reach the higher grass. This would occur through natural selection that would favor the extreme traits (alleles of long neck) of long necks in the population.
Explanation:hope it helps you
Answer:
The evolutionary feature you will expect you see in the tortoises on the island is longer necks.
Explanation:
Longer necks will be able to occur through natural selection. Tortoises would be able to reach for higher grass when grass isn't available from lower. This is a favorable trait.

Which would NOT likely be used as evidence of evolution?
Answers
Answer:
what is there to pick from?
Explanation:
The option that does not provide evidence that living things have been evolving for millions of years is intelligence. The correct option is C.
What is evidence?In science, evidence refers to any observations, measurements, or facts that support or refute a hypothesis or theory.
Intelligence is not a factor that provides evidence for evolution. The process of evolution is driven by natural selection, genetic mutations, and other biological factors, not intelligence.
On the other hand, the other answer choices are all factors that provide evidence for evolution:
(A) Fossil record: provides evidence of changes in species over time.
(B) Natural variation within a species: provides the raw material for evolution to act upon.
(D) Homologous structures of living organisms: provide evidence of common ancestry and evolution over time.
(E) Similarities in embryological development: provide evidence of shared evolutionary history and common ancestry.
Thus, the correct option is C.

Explanation:
Cell membrane is found in both animal and plant cells
Explanation:
Mitochondria are membrane-bound organelles found in both plant and animal cells, and provide energy for the cell by converting different forms of reactants into ATP. The cell membrane is present in both types of cells and separates the environment from the inside of the cell, and provides cell structure and protection.
is it more beneficial for humans to undergo sexual reproduction than asexual reproduction?
Answers
Answer:Advantages and disadvantages of sexual and asexual reproduction
Sexual reproduction involves two parents and the joining of male and female gametes during fertilisation. The offspring inherit a mixture of genes from both parents, so are different to each other and their parents.
The advantages of sexual reproduction:
produces genetic variation in the offspring
the species can adapt to new environments due to variation, which gives them a survival advantage
a disease is less likely to affect all the individuals in a population
In asexual reproduction there is only one parent. The offspring are clones of the parent and each other.
The advantages of asexual reproduction include:
the population can increase rapidly when the conditions are favourable
only one parent is needed
it is more time and energy efficient as you don't need a mate
it is faster than sexual reproduction
The disadvantages of sexual reproduction:
time and energy are needed to find a mate
it is not possible for an isolated individual to reproduce
The disadvantages of asexual reproduction include:
it does not lead to genetic variation in a population
the species may only be suited to one habitat
disease may affect all the individuals in a population
Examples in the natural world
Bacterial reproduction
Bacteria, such as E. coli, reproduce asexually. An advantage of this is that they can produce many bacteria very quickly. A disadvantage is that all of the bacteria are genetically identical. If an antibiotic was used on the bacteria, then all of them would die. The population would be wiped out. The only way for variation to be introduced into the population is by random mutation.
Rabbit reproduction
Most animals reproduce sexually, for example, rabbits. The process of sexual reproduction introduces variation into the species because the alleles that the mother and the father carry are mixed together in the offspring. A disadvantage is that sexual reproduction takes longer than asexual reproduction. A mate must be found, the egg must be fertilised by sperm, and then the offspring develop. The benefit of introducing genetic variation into the species, however, outweighs this disadvantage. If a disease were to hit the rabbit population, then perhaps not all of the rabbits would be affected because of the variation in the population. This means that some individuals would survive and be able to reproduce and generate more offspring.
Asexual and sexual reproduction in fungi
Some fungi are able to reproduce both sexually and asexually. Fungi reproduce using spores which they release into the environment. A new fungus will grow from the spore. The Coprinus cinereus fungus can produce spores by sexual reproduction to help create variation in the species. This method of reproduction is advantageous when the environment is changing because the variation introduced leads to an increase in the probability that a variant that can deal with the change. Coprinus cinereus also produces spores by asexual reproduction. These spores can be produced quickly and in large numbers to enable many individual fungi to develop. A disadvantage of these spores is that they generate offspring that are unlikely to be resistant to unfavourable conditions because they are all genetically identical.

Some mushrooms can carry out both asexual and sexual reproduction depending on their environment

Water molecules have a strong attraction to one another.
What property best describes this attraction?
Choose 1 answer:
A
Hydrophobic
B
Cohesion
C
Density
D
Adhesion
Answers
Answer:
The correct answer is B: Cohesion
Explanation:
Cohesion is the ability of water molecules to be strongly bonded together. This happens due to the polarity of water molecules. Since water is made up of two positive hydrogen ions that combine with one negative oxygen ion to form a hydrogen bond. Hence, the molecular structure of water enables hydrogen irons to attract oxygen ions that create a strong polar bond between water molecules.

Develop an argument as to whether or not the structures and functions of the nervous system work to help prevent injuries. Use evidence and real-world knowledge to support your argument.
Answers
Answer:
Yes.
Explanation:
Yes, the structures and functions of the central nervous system work to help prevent injuries with the help of bone. The main line of defense of central nervous system is the bones of the skull and spinal column, which create a hard physical barrier to injury. If these line of defense are not present for central nervous system so it has more chances to get injury so we can say that the structures and functions of the nervous system helps to prevent injuries.
