Answer:
Explanation:
1 The first time the word cell was used to refer to these tiny units of life was in 1665 by a British scientist named Robert Hooke. Hooke was one of the earliest scientists to study living things under a microscope
2 Leeuwenhoek found animalcules
Dutch biologist and microscope pioneer Antoni van Leeuwenhoek observed in the late 1600s when he proclaimed the existence of a world of microscopic “animalcules”
3 The three parts of the cell theory are as follows: (1) All living things are made up of cells, (2) Cells are the smallest units (or most basic building blocks) of life, and (3) All cells come from preexisting cells through the process of cell division.
4 Four Common Parts of a Cell
Although cells are diverse, all cells have certain parts in common. The parts include a plasma membrane, cytoplasm, ribosomes, and DNA. The plasma membrane (also called the cell membrane) is a thin coat of lipids that surrounds a cell.
5 Ribosomes are small structures where proteins are made. They are found in both prokaryotic and eukaryotic cells
6 The main role of DNA in the cell is the long-term storage of information. ... The major function of DNA is to encode the sequence of amino acid residues in proteins, using the genetic code. To read the genetic code, cells make a copy of a stretch of DNA in the nucleic acid RNA.

White blood cells can be called the strong defender of our body from foreign substances. These cells are responsible for increasing the immunity power of a person.
Explanation:
Monocytes cells are also called white blood cells. These cells play a role an antigen that fight with outer danger and protect other white blood cells as well and prepare other cells to reduce the dead blood cells and renovate new blood cells.
These cells prevent cancer cells and fight against foreign antigens or particles. The Monocytes are the cells that develop in the bone marrow of a person and develop red blood cells.
In white blood cells, some macrophages cells are called the scavengers in the bone marrow that eat foreign particles and increase the immunity power of the person. The diagnose can be done with the help of blood testing.

Scientists have been studying threats to coral reefs. The percent of reefs affected by various threats are shown in the figure below. A future global temperature increase may affect all categories on the figure. Predict which category would change the most from global temperature increases and propose a testable question that scientists could study.
a. The biggest effect will be on the far right column that includes thermal stress with a greater percentage of reefs falling into the low and medium threat categories. Scientists could test whether reefs that have greater fishing risk also have greater thermal risk.
b. The biggest effect will be on the far right column that includes thermal stress, with a greater percentage of reefs falling into the high and very high threat categories. Scientists could test whether reefs that have greater temperature changes have greater increases in watershed-based pollution.
c. The biggest effect will be on the far left column that includes fishing, with a greater percentage of reefs falling into the high and very high threat categories. Scientists could test whether increased fishing causes increased marine-based pollution.
d. The biggest effect will be on the far left column that includes fishing, with a greater percentage of reefs falling into the low and medium threat categories. Scientists could test whether reefs that have greater temperature changes have greater increases in fishing threats.
Answers
Answer:
It's B
Explanation:
Temperature rise will eventually end up putting coral reefs into the high threat categories, not fishing and DEFFINITELY not lowering their "risk" factor.
Coral reefs are the organisms of the aquatic ecosystem. The column includes the thermal stress that will be affected the most as the reefs fall into high and very high threats are huge. Thus, option B is correct.
What is the effect of thermal stress on coral reefs?Due to an increase in pollution and global warming, the oceans have heated up, which results in thermal stress and leads to coral bleaching and threat to the coral reefs.
The percentage of the very highly threatened, highly threatened, slightly threatened, and threatened reefs are seen majorly due to the thermal stress. Thermal stress is in increases amount due to oceanic warm-ups.
The thermal stress due to increased carbon dioxide activities and acidity leads to coral bleaching causes the destruction of the reefs and their endangerment.
Therefore, option B. the far right column labeled thermal stress has the biggest effect on the coral reefs.

Changes in groups of organisms overtime produce variations in a population. This relates to _______.
A. Macroevolution
B. Microevolution
C. Both
Answers
C. Both.
Explanation:
Changes that occur in different groups of organisms overtime that produce variations in a population relate to both macroevolution and microevolution. Although they are different, they both relate to this subject.
Macroevolution is on a big scale. This goes over organisms ancestors, large trends, and other groups of species that may be involved. This goes over a longer bit of time and is not as in depth.
Microevolution is on small scale. This goes over the different changes that may have occurred in allele frequencies from things like genetic drift, natural selection, or mutation. This goes in much more depth and looks deeper into what type of evolution may have happened.

Consider this animal cell. The organelles in an animal cell are labeled. Part A is a structure with stacked membranes, part E represents small dots on the nucleolus, part F is a network of hollow tubes, flattened sheets, and round sacs, and part G is a bean-shaped structure with folding inside. Which organelle is responsible for producing the energy for cellular processes? organelle A organelle E organelle F organelle G
Answers
Answer:
G is a bean-shaped structure with folding inside
Explanation:
The Bean shape structure is the shape of Mitochondria, therefore it is the organelle of cellular respiration.
Kreb's Cycle and oxiadative phosphorylation are the major stages of of Cellular respiration which takes place in the mitochondria.
Cellular respiration is the process of extracting the energy as ATPs contained in foods(glucose, fatty acids, Aa) by combining them with oxygen.
Electron transport chains generate the energy for pumping protons to generate the energy, for ATPs synthesis, by enzyme ATPase synthases.

Answers
Answer:
Net primary productivity of the tropical rain-forest = 3 kcal/m2/yr
Explanation:
Given:
Gross primary productivity in a tropical rain-forest = 6 kcal/m2/yr .
Respiration = 3 kcal/m2/yr
Find:
Net primary productivity of the tropical rain-forest
Computation:
⇒ Net primary productivity of the tropical rain-forest = Gross primary productivity in a tropical rain-forest - Respiration
⇒ Net primary productivity of the tropical rain-forest = 6 kcal/m2/yr - 3 kcal/m2/yr
Net primary productivity of the tropical rain-forest = 3 kcal/m2/yr
