If blood cells don't have a nucleus and don't reproduce, how do we get more blood?
What happens to the dead blood cells?
Answers
Answer:
Red blood cells are considered cells, but they lack a nucleus, DNA, and organelles like the endoplasmic reticulum or mitochondria. Red blood cells cannot divide or replicate like other bodily cells. They cannot independently synthesize proteins,The nucleus is the cell's brain which controls much of its functions. An animal cell or eukaryotic cell will therefore die without a nucleus. The cell would not know what to do without a nucleus and there would be no cell division. The synthesis of proteins will either stop or shape wrong proteins.When red cells die, hemoglobin is broken up: iron is salvaged, transported to the bone marrow by proteins called transferrins, and used again in the production of new red blood cells

A partial solar eclipse occur when moon, sun and earth is not exactly aligned.
Explanation:
A solar eclipse occurs when moon, sun and earth aligned and such alignment coincides at a new moon. In this alignment moon is in the between sun and earth which causes shadow over the earth.
A partial solar eclipse occur when moon, sun and earth is not exactly aligned.
Because earth is round some parts of the world can observe complete solar eclipse while some parts of the world can observe partial solar eclipse and some parts of the world simply does not observe any solar eclipse because they are having a night during that time.

B. have orderly crystalline shapes
Explanation:
When elements repeat themselves in the same ratio and develop into a repeating shape, the minerals must have orderly crystalline shape.
This informs the long range ordering of the substance they form into. We say such substances are crystalline in nature. Those without this orderliness are tagged as being amorphous and without shape or form. Each crystal can be used to identify the original substance as it is a fundamentally ordered unit.Organisms that cannot use sunlight directly obtain energy by

Answers
Answer:
Organisms
Explanation:
Organisms that cannot use sunlight directly obtain energy by consuming plant or other organisms that have consumed plants.
These organism are heterotrophs.
Plants are autotrophs as they produce their own food on their own. They are the primary producers in the ecosystem by means of photosynthesis. Heterotrophs relies on the food produced by autotrophs. They can obtain this by either feeding on plant matter or by feeding on primary consumers that feeds on plants.Squirrels exhibit altruistic behavior.

What will happen over time if a population of organisms from the same species is physically separated and can't reproduce with one another?
the two populations will become different species over time due to accumulated mutations occuring in both populations
The two populations will remain the same species even as mutations occur randomly in the different populations
Answers
Answer:
Explanation:
the two populations will become different species over time due to accumulated mutations occuring in both populations
The two populations will become different species over time due to accumulated mutations occuring in both populations. Thus, option A is correct.
What are species and population?Species has been defined as the group of the potentially interfertile organisms that can be produce the fertile descendence. Organisms of the same species could live in the different areas, while the organisms of the same population use to live in only a particular area.
A population has been known as the group of the individuals of the same species that use to live in the given area. The individuals of that given population may or may not cross in order to produce the fertile descendence. Organisms of the same species that can live in the different areas, and while the organisms of the same population live in only one area.

Answers
Answer:
The correct answer is - C. by indicating whether the water is too acidic or basic.
Explanation:
pH meter or pH scale is the color indicating scale to measure the acidity or basicity of the particular solution of the element. pH meter measures the hydrogen ion activity of the freshwater or saline water of the hydrosphere and if it is acidic or basic. It helps in determining if the water can be a drink or if the water body has an appropriate pH level for the organisms to live.
Thus, the correct answer is - C.

Which is not a rule scientists use to
determine the relative age of rocks?
Answers
A fairly easy and uncomplicated method of determining relative age is the superposition of rock units. According to the rule, the oldest beds are at the bottom and the youngest ones are at the top of a succession of undeformed sedimentary rocks.
How did you establish the relative ages of the rock units using what principles?The lithology of a rock, the principle of inclusions, the principle of biological succession, the principle of superposition, the principle of original lateral continuity, and the principle of cross-cutting relationships are all utilized to establish a rock's relative age.
How is relative age calculated? What is relative age?By using relative dating, scientists cannot pinpoint a fossil's exact age, a rock, but examine a line of rocks to attempt to determine when an event took place.
