The signal for apoptosis can come from outside or inside the cell. Give one example when the signal comes from outside the cell
Svetach [21]

Answer:

- A signal for apoptosis that comes from outside the cell is when a cell detaches from extracellular matrix. If this happens, a transmembrane signal is triggered.

- Two examples of cellular occurrences that would prompt an apoptosis signal from inside the cell are:

1. Damaged DNA

2. Increase of cytosolic calcium concentration

Explanation:

Apoptosis can be activated from an intrinsic or an extrinsic pathway. The intrinsic pathway is activated when a cell senses stress (for example, damaged DNA or high cytosolic calcium concentration) and triggers death proteins to activate apoptosis mechanism inside of it; the extrinsic pathway refers to the apoptosis triggered by signals that come from other cells. In this scenario, ligands bind to cell-surface death receptors and activates a death-inducing signal.

Pea plants were particularly well suited for use in Mendel's breeding experiments for all of the following reasons except that a
solniwko [45]

Answer:

. d. peas have an unusually long generation time

Explanation:

Gregor mendel is a scientist, he was bored 20th July,1822. He carried out an experiment using pea plant and he is reffer to as the father of genetist. Mendel used seven traits of the pea plant in his experiments this include flower color which is either purple or white, flower position which is either axil or terminal stem length which could be long or short, seed shape (round or wrinkled), seed color (yellow or green), pod shape (inflated or constricted) and pod color (yellow or green). He uses pea plant because of the following reason,

pea plant has many observable characteristics that could be used such as flower colors,seed shape.

Pea plant is an annual crop that matures early, so earliness to maturation makes Mendel select pea

Mating in pea plant can be controlled. Pea plant are self fertilizing crop but he decided to control the mating pattern by cross fertilize them and avoiding contamination from other pea plant.

The experiment with pea pant would produce enough seeds for subsequent generation.

This experiment made Mendel propound 2 laws, law of segregation of gene and law of Independent assortment of gene.

How would a loss of chlorophyll most likely affect cellular respiration in plant
CaHeK987 [17]

Answer:

The correct answer is A less glucose will be available for energy production.

Explanation:

Chloroplast is an important cell organelle present in the green parts of a plant.Chloroplast is the site  of photosynthesis which ultimately deals with generation of glucose molecule for both transport and storage.

         If chloroplast is lost then less glucose will be available for cellular respiration.

What is the common name of plant #3 and what biome would it most likely grow in? Name one adaptation that helps it survive in it
Dmitry [639]

Answer:

A biome is a large area characterized by its vegetation, soil, climate, and wildlife. There are five major types of biomes: aquatic, grassland, forest, desert, and tundra, though some of these biomes can be further divided into more specific categories, such as freshwater, marine, savanna, tropical rainforest, temperate rainforest, and taiga.

Aquatic biomes include both freshwater and marine biomes. Freshwater biomes are bodies of water surrounded by land—such as ponds, rivers, and lakes—that have a salt content of less than one percent. Marine biomes cover close to three-quarters of Earth’s surface. Marine biomes include the ocean, coral reefs, and estuaries.

Grasslands are open regions that are dominated by grass and have a warm, dry climate. There are two types of grasslands: tropical grasslands (sometimes called savannas) and temperate grasslands. Savannas are found closer to the equator and can have a few scattered trees. They cover almost half of the continent of Africa, as well as areas of Australia, India, and South America. Temperate grasslands are found further away from the equator, in South Africa, Hungary, Argentina, Uruguay, North America, and Russia. They do not have any trees or shrubs, and receive less precipitation than savannas. Prairies and steppes are two types of temperate grasslands; prairies are characterized as having taller grasses, while steppes have shorter grasses.

Forests are dominated by trees, and cover about one-third of the Earth. Forests contain much of the world’s terrestrial biodiversity, including insects, birds, and mammals. The three major forest biomes are temperate forests, tropical forests, and boreal forests (also known as the taiga). These forest types occur at different latitudes, and therefore experience different climatic conditions. Tropical forests are warm, humid, and found close to the equator. Temperate forests are found at higher latitudes and experience all four seasons. Boreal forests are found at even higher latitudes, and have the coldest and driest climate, where precipitation occurs primarily in the form of snow.

Deserts are dry areas where rainfall is less than 50 centimeters (20 inches) per year. They cover around 20 percent of Earth’s surface. Deserts can be either cold or hot, although most of them are found in subtropical areas. Because of their extreme conditions, there is not as much biodiversity found in deserts as in other biomes. Any vegetation and wildlife living in a desert must have special adaptations for surviving in a dry environment. Desert wildlife consists primarily of reptiles and small mammals. Deserts can fall into four categories according to their geographic location or climatic conditions: hot and dry, semiarid, coastal, and cold.

A tundra has extremely inhospitable conditions, with the lowest measured temperatures of any of the five major biomes with average yearly temperatures ranging from -34 to 12 degrees Celsius (-29 to 54 degrees Fahrenheit). They also have a low amount of precipitation, just 15–25 centimeters (six to ten inches) per year, as well as poor quality soil nutrients and short summers. There are two types of tundra: arctic and alpine. The tundra does not have much biodiversity and vegetation is simple, including shrubs, grasses, mosses, and lichens. This is partly due to a frozen layer under the soil surface, called permafrost. The arctic tundra is found north of boreal forests and the alpine tundra is found on mountains where the altitude is too high for trees to survive. Any wildlife inhabiting the tundra must be adapted to its extreme conditions to survive.
