Answer:
One of the central conclusions Mendel reached after studying and breeding multiple generations of pea plants was the idea that "[you cannot] draw from the external resemblances [any] conclusions as to [the plants'] internal nature." Today, scientists use the word "phenotype" to refer to what Mendel termed an organism's "external resemblance," and the word "genotype" to refer to what Mendel termed an organism's "internal nature." Thus, to restate Mendel's conclusion in modern terms, an organism's genotype cannot be inferred by simply observing its phenotype. Indeed, Mendel's experiments revealed that phenotypes could be hidden in one generation, only to reemerge in subsequent generations. Mendel thus wondered how organisms preserved the "elementen" (or hereditary material) associated with these traits in the intervening generation, when the traits were hidden from view.
It is important to use an organism with a recessive phenotype in a cross with an organism of an unknown genotype to identify the recessive traits.
What are phenotype and genotype?The observable traits of an individual are the result of gene expression; the clinical manifestation of a person with a certain genotype is called the phenotype of an individual. Some examples of the phenotype are height, skin color, eye color, hair nature, etc.
The term "genotype" refers to an organism's whole gene pool, or, in other words, the genetic makeup of that creature. The phrase can also be used to describe the alleles, or different forms of a gene, that an organism carries in a more specific meaning.
A recessive phenotype is used in a cross with an organism of unknown Genotype to identify the recessive traits.

Which of the following might be an adaptation for a predator? AS SOON AS POSSIBLE NEED HELP PLS THX
Answer:
we need the answers
Explanation:
Answer:
Many predators have adaptations that help them survive in the wild. For example, the snake shown below has camoflauge coloring to look like its surroundings. This gives it the element of surprise when going to attack its prey. These adaptations help the predator in hunting for food. Predators have "weapons", or adaptations, that help them hunt and kill prey. Predators' three main "weapons" are teeth, claws, and jaws. The lion below has all 3 of these "weapons" or adaptations that are used for catching its prey. A lion has sharp claws for catching and grabbing hold prey such as a zebra, and strong jaws and teeth for biting and killing the zebra and for ripping off and chewing the meat.

One result of climate change is that ocean temperatures are increasing. If the temperatures continue to rise, what effect will that have on the oceans’ ability to retain CO2? How might this change affect the atmosphere? THIS IS SCIENCE WOULDNT LET ME SELECT IT
Answer:
See explanation
Explanation:
There is an equilibrium that exists between the carbon dioxide in the air and the carbon dioxide in the oceans. The temperature of the water affects its ability to hold carbon dioxide.
Hence, as the global temperature continues to rise and the water becomes warmer, its ability to hold carbon dioxide decreases. When this happens, the gas exchange across the air-ocean boundary is affected. There is now too much CO2 in the atmosphere owing to the disturbance of its air- ocean exchange equilibrium leading to more rise in temperature due to global warming.

9. yeah, true
10. c
Explanation:
Pro phase is the starting stage of the division where the cell division begins. Spindle fibers are broken into half and the type of division that is present in gametes is reduction division that is the meiosis. Synapsis occurs during mitosis.
What is synapsis ?It is defined as the stage in which the pairing of the homologous chromosomes take place.
Chromosomes do not line at the equator as the lining of the chromosomes at the equator occurs on the stage of mitosis where it is possible to see the V,J and L shapes of the paired chromosomes. After this stage the exchange of genetic material takes place.Chromatin do not change into chromosomes in the metaphase.
Mitosis is present only to make the duplicate copies of the cell. The identical daughter cells are made when the division of mitosis is taking place in the cell. Chromosomes are first visible in the prophase. A centromere holds two sister chromatids together.
In meiosis crossing over takes place in anaphase 1.

Answer:
Answer below !

2) Temperature
3) Glucose Availability
Hope I helped and have a great day ∩^·ω·^∩ !
Cellular respiration in living tissues is reduced at low temperatures. The amount of kinetic energy needed for chemical reactions like cellular respiration to occur decreases as temperature rises.
What variable that influence the rate of cellular respiration?Since all living cells require both glucose and oxygen to operate properly, variations in the concentration of glucose have an effect on the rate of cellular respiration. If a cell's glucose level is low, it cannot produce energy in the form of ATP molecules.
High oxygen concentrations enable cells to perform aerobic respiration, which uses oxygen to build ATP and generates more ATP than anaerobic respiration, which occurs when oxygen is not present.
As a result, increased cellular respiration is often associated with warmer temperatures.
Therefore, Oxygen Concentration, Temperature, Glucose Availability
