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?
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

The amount of energy that is available to organisms above producers is equal to the gross primary productivity minus the amount of organic material used in respiration (Option D).
Producers (e.g, plants, algae) are all autotrophic organisms at the first trophic level of the food chain in a particular ecosystem.
Gross primary productivity refers to the net amount of carbon fixed by producers in a particular ecosystem.
Moreover, the net primary productivity refers to the net amount of carbon dioxide that is fixed by producers (i.e., organic material) in an ecosystem minus the amount of organic material that is used for metabolic activities, i.e., during cellular respiration.
Therefore, the net primary productivity (NPP) can be estimated as the gross primary productivity (GPP) minus respiration rate (R):
NPP = GPP - RIn conclusion, the amount of energy that is available to organisms above producers is equal to the gross primary productivity minus the amount of organic material used in respiration (Option D).

Which is not a rule scientists use to
determine the relative age of rocks?
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.

Organisms that cannot use sunlight directly obtain energy by
consuming plants or other——————
that have consumed plants
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.what's the answerrrrrr

In each case, what is the end product of burning the fossil fuel, and where does it go?
Answer:
when fossil fuels are burned they release carbon dioxide and other greenhouse gases which traps heat in the atmosphere and making them primary contributors to global warming and climate change
Explanation:
When fossil fuels are burnt, they generally give rise to six different kinds of products, these are carbon dioxide, sulfur dioxide, carbon monoxide, lead, nitrogen oxides, and particulate matter.
• Of these, the main product of the burning of fossil fuels is carbon dioxide.
• When the burning of fossil fuels takes place, the carbon dioxide and other greenhouse gases get released into the atmosphere in excess amounts and trap heat more than expected.
• Thus, making them the primary contributors to climate change and global warming.

Answer:
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.help please!
