Answer:
Not all members of a species are the same. Every species exhibits
variation.
For example, some beetles are green, while others are brown.
Not all individuals in a population will survive to reproduce. Those that do, pass their traits, genes to their offspring.

Got it right. Hope it helps :)
In mature animals when do cells still need to differentiate?
Answer:
As an organism develops, cells differentiate to form different types of cells. Most types of animal cell differentiate at an early stage. Many types of plant cells retain the ability to differentiate throughout life. In mature animals, cell division is mainly restricted to repair and replacement.
Explanation:
''.''
In mature animals cells differentiate during : Repair and replacement of animal cells
Cells differentiate in organisms and plants to create more cell types, as the organism and plants continue to mature. While cell differentiation in animals occur mostly before maturity, plants cells continue to differentiate until they die.
While in mature animals, cells differentiates at maturity only when the cells of the mature animal needs repair or replacement due to damage caused to the a cell or tissue.
Hence we can conclude that in mature animals cells differentiate during repair and replacement of cells.

(3) 5000°C and 1.5 million atmospheres
(4) 5000°C and 3.0 million atmospheres
Answer:
(4) 5000°C and 3.0 million atmospheres
Explanation:
The inferred temperature is 5000°C and pressure of Earth's interior is 3.0 million atmospheres at a depth of 3,000 kilometers. At the depth of 3000 kilometers, core of the earth is present which is very hot and it is mostly consist of iron. The inner core has a radius of about 1,220 kilometers while the outer core is about 1,400 miles thick which comprise of iron, Nickle, gold, platinum, and uranium elements.

Answer:
It is Alkene..........
Answer:
Alkenes
Explanation:
Alkene is a hydrocarbon chain that has a carbon to carbon double. Alkenes are considered 'acyclic' because it has one carbon to carbon double. Since they contain less than a maximum number of hydrogen atoms they are unsaturated.

Explanation:
Why are viruses considered nonliving but bacteria are considered living? Give two reasons.
Not a long life story but a simple two reasons.
Answer:
1-Viruses also lack the properties of living things: They have no energy metabolism, they do not grow, they produce no waste products, and they do not respond to stimuli.
2-They also don't reproduce independently but must replicate by invading living cells.

Which of the following correctly identifies a lymphatic organ and describes how it
can fight cancer? (2 points)
1) Lymph vessel; removes fluid from tissues
2) Lymph trunk; returns lymph to the blood
3) Spleen; replaces damaged red blood cells
4) Thymus; exposes lymphocytes to antigens
All of the statements correctly identify a lymphatic organ. In vertebrates, the lymphatic organs, also known as the lymphoid system, are an organ system that is a part of the immune system and works in conjunction with the circulatory system.
The Lymphatic OrgansLymphatic vessels, which are found all over your body and transport lymph away from tissues, are a network of capillaries (microvessels) and a huge network of tubes.By emptying into the corresponding subclavian veins, the lymph ducts, which are formed by the lymph trunks, restore lymph to circulation.Red blood cells that are outdated or damaged are eliminated by the spleen, which also removes cellular waste from circulation.Training specific white blood cells known as T-lymphocytes or T-cells is the thymus gland's main job.Hence, all of the statements correctly identify a lymphatic organ.
How lymphatic system fights Cancer?Regional lymph nodes, which are predictive of distant organ metastases and poor survival, are accessible to tumor cells via lymphatic arteries.As the lymph fluid moves through the lymph nodes, it is filtered. B cells and T cells, two types of white blood cells, assault any viruses or bacteria they discover in the lymph.To learn more about the Lymphatic System refer to:

Which plant propagation process insures some genetic diversity?
Answer:
Seed propagation takes place during sexual reproduction. The production of seeds through auto-pollination or crossed pollination ensures some genetic variation.
Explanation:
Seeds ensure the existence of genetic variation between plants. There are two general crossing systems in plants, which depend on pollination type.
Self-pollination occurs when the flower pollen is transferred to the same flower stigma, reaching that individual egg to fertilize it. These are autogamous systems. Crossed pollination occurs when the mature pollen is driven by different pollinator agents from one flower to another, reaching the other flower stigma and fertilizing its eggs. These are xenogamous systems.Sexual reproduction gives more possibilities to different alleles of a gene that did not appear in one generation to express in the next generation. Both types of pollination allow genetic variation, however by the occurrence of crossed pollination there are more chances to ensure the variability of the species and survival to environmental changes. While by self-pollination there are more chances to express the same genotype of the parental plant. The Xenogamous system has the advantage of avoiding the effects of endogamy in a population.
What causes antibiotic resistance?
- Only using antibiotics when you are also doing radiation therapy
- Only using antibiotics when you are also doing chemotherapy
- Any use of antibiotics causes resistance
- We do not know
Answer:
Antibiotic resistance occurs when bacteria change in response to the use of these medicines. Bacteria, not humans or animals, become antibiotic-resistant. These bacteria may infect humans and animals, and the infections they cause are harder to treat than those caused by non-resistant bacteria.

Describe some of the reasons for exploring the mid-Cayman ridge.
Answer:
Life on Earth goes back almost 4.1 billion years, but photosynthesis as characterized by cyanobacteria only appeared around 3.5 billion years ago (Ga). Since life on Earth predates photosynthesis, the exploration of this deep-water environment that lacks any source of light could provide information on what those life forms looked like.
