In the diagrams of mitotic cell division shown, which structure is present in diagram B but in diagram A?
-centriole
-cell plate
-cell membrane
-cytoplasm
Answer:
-cell plate
Explanation:
Diagram A is an animal and diagram B is a plant cell. When dividing through mitosis plant cells form a cell plate during the mitotic phase. However, cell plates are not found in animal cells, as they do not have cell walls. Therefore, the answer must be cell plate.
NEED HELP!!! How do vestigial organs provide evidence for the theory of evolution? A Vestigial organs show differences between our DNA and the DNA of amoebas. B Vestigial organs show traits that a species once needed to have to perform certain tasks. C Vestigial organs show the variation in genes that can exist within one species. D Vestigial organs show how many cells organisms of a species once had.
Answer:
Vestigial organs show traits that a species once needed to have to perform certain tasks
Explanation:
B. Vestigial organs provide evidence for the theory of evolution:
"Vestigial organs show traits that a species once needed to have to perform certain tasks."
What do you mean by vestigial organs?
"Vestigial organs are the organs that have no apparent function and are considered to be the residual parts from the past ancestors."
What is theory of evolution?
"Theory of evolution is a scientific theory of the origin of species of plants and animals."
What do you mean by species?
"A species is often defined as a group of organisms that can reproduce naturally with one another and create fertile offspring."
What is a trait?
"A trait, as related to genetics, is a specific characteristic of an individual."
How are vestigial organs related to theory of evolution?
"Vestigial organs are often homologous to organs that are functioning normally in other species. Therefore, vestigial organs can be considered evidence for evolution, the process by which beneficial heritable traits arise in populations over an extended period of time."

Rebecca’s family uses their house’s heating system to stay warm in the winter. How do they know when their system is at equilibrium?
A. The house temperature balances the set temperature and the system shuts off.
B. The house temperature is changing and the system is rapidly changing from on to off then back again.
C. The house temperature is lower than the set temperature and heat is on.
D. The house temperature is higher than the set temperature and the cooling is on.
Thank you.
Answer: A
Explanation:
Answer:
A. The house temperature balances the set temperature and the system shuts off.
Explanation:
Equilibrium is a state in which the competing factors of a system are in balance. In the case of the heating system, the house temperature and set temperature would be the same and the system would turn off.

Which explains the relationship between the respiratory system and the circulatory system in an organism?
A. The respiratory system takes in oxygen. The circulatory system delivers the oxygen to cells.
B. The respiratory system takes in oxygen. The circulatory system removes wastes from the body.
C. The respiratory system delivers oxygen to cells. The circulatory system controls the body's activities.
D. The respiratory system delivers oxygen to cells. The circulatory system provides support to cells.
A. The respiratory system takes in oxygen. The circulatory system delivers the oxygen to cells.
The respiratory system is defined as the set of tissues and organs involved in the uptake of oxygen from the atmosphere and the release of carbon dioxide produced during aerobic respiration.
This gas exchange is also called breathing or external respiration. Thus the correct option is A that is the respiratory system takes in oxygen. The circulatory system delivers the oxygen to cells.
In which system lungs and heart are present?Lungs are present in respiratory system and heart is present in circulatory system.
The circulatory system is refers to as which delivers oxygen and nutrients to cells and takes away wastes. The heart pumps oxygenated and deoxygenated blood through blood vessels which include arteries, veins and capillaries.

It's D
+jjjjjjjjjjjjjhj
The long-term effects which may arise from the use of genetically modified crops is a controversial issue associated with the use of GM crops. They are reported to be having serious health impacts.
What is genetically modified crops ?Some crops are designed using genetic techniques to insert them some desired characteristics such as microbial resistant, high yield, taste, bigger size etc. Genetic engineering techniques such as CRISPER genes are common today to modify the crops in order to meet the desired features.
Genetically modifying food is a relatively new process, thus it is unclear how it will affect food safety in the long run. Human health is a major concern with regard to the drawbacks. While study is ongoing, scientists have not yet demonstrated that eating GMO foods is unhealthy.
Allergic reactions, genetic changes, devastations of good insects and their diversity etc. are the drawbacks of GM crops. Some even leads to cancer. Hence, option A is correct.

Differentiate the components of fluid connective tissue?
Answer:
The components of the fluid connective tissue are red blood cells, white blood cell and blood platelets
Explanation:
The connective tissues refer to tissues composed of some class of matrix. The blood is considered a fluid connective tissue which is composed of red blood cells (erythrocytes), white blood cell (leukocytes) and blood platelets (thrombocytes). Erythrocytes are cells that contain hemoglobin and whose function is to transport oxygen to the body. Leukocytes are cells involved in the immune responses which act to protect the body against both foreign pathogenic invaders. Finally, thrombocytes are cell fragments that form clots and stop bleeding.

Glucose provides energy for cells. Different cells have different mechanisms for glucose intake. Intestinal cells contain proteins that transport glucose against its concentration gradient. These proteins couple the movement of glucose to the movement of sodium down its concentration gradient. Red blood cells have transporter proteins embedded in their membranes. When bound by a glucose molecule, these proteins change shape and allow glucose to move down its concentration gradient into the cell.
Based on this information, what type of transport is used for glucose in blood and intestinal cells?

what would happen if the igneous rock was first exposed to energy from the sun
Answer:
If there is too much heat or pressure, the rock will melt and become magma. This will result in the formation of an igneous rock, not a metamorphic rock. Consider how granite changes form. Granite is an igneous rock that forms when magma cools relatively slowly underground
Explanation:
Answer:
An igneous rock can change under pressure to metamorphic. A igneous rock can turn into another igneous rock by melting and solidifying, it can turn into a sedimentary rock by getting weathered then recemented, or it can turn into a metamorphic rock by being subjected to great heat and pressure
