Answer:
Some scientists believe that there were huge fires and the skies were dark and full of pollution due to a meteor exploding and killing off the dinosaurs, and if it's true that this occurred, the Ostrich evolved to be a land animal due to it being too dangerous in the air for them. The long neck may have developed to help them get food that was higher up which is the same speculation for the Giraffe. To stay on land they had to be stronger, bigger, and faster than they were in flight.

Plants do photosynthesis to make the glucose and cellular respiration to break the glucose down for energy.
True
False
What process occurs in Box A?
a. A scheme of cellular respiration. At box A, which is located in the cytosol, glucose turns into pyruvate with release of ATP and electrons carried by NADH.
b. Pyruvate from this stage is used in a cycle in box B, which is located in the mitochondrion.
c. As a result, ATP, CO2, and electrons carried by NADH and FADH2 are released.
d. The electrons carried by NADH and FADH2 from boxes A and B are used in box C (inside the mitochondrion) for transformation of a substance marked D (that comes from the cytosol) into a substance marked E (released to the cytosol) with release of ATP.
Answer:
The process occurring in Box A is Glycolysis
Explanation:
Glycolysis is the pathway by which glucose, a six-carbon molecule is oxidized to molecules of pyruvate, a three-carbon molecule with the release of ATP and electrons which are carried by NADH molecules.
The process occurs in the cytoplasm of cells and requires 10 glycolytic enzymes.
The pyruvate molecules from glycolysis is first oxidized to acetyl-CoA and carbon dioxide molecules. The acetyl-CoA molecules enter the citric acid cycle occurring in the mitochondria and are used up in the production of ATP, CO2, and electrons carried by NADH and FADH2.
The electrons carried by NADH and FADH2 from glycolysis and citric acid cycle are used in the oxidative phosphorylation pathway occurring inside the mitochondrion for transformation of oxygen molecules into water molecules with release of ATP.
What are Metabolic Reactions?
Metabolism refers to all of the chemical reactions that take place inside living cells. Unicellular and multicellular organisms must control their metabolism in order to survive.

how does proper waste management help prevent pollution
Answer:
When waste is properly managed by recylcling, it does not end up in mills or habitats. Therefore it does not pollute the environment.
True or False - Statistical significance is commonly reported as odds ratios
(ORs), relative risks (RRS), or hazard ratios (HRs).
Answer:
The p-value is an estimate of whether the difference is a statistical accident or due to random chance. ... Epidemiological research usually uses different statistics to analyze their results. Epidemiological results are commonly reported as odds ratios (ORs), relative risks (RRs), or hazard ratios (HRs).
Are humans heterotrophs or autotrophs? Pleas Help Me.. Thx:)
Answer:
Heterotroph
Explanation:
They require other sources to sustain themselves and cannot produce their own energy.
Answer:
Heterotrophs
Explanation:
Producers are the most common type of autotrophs because they are able to make food out of energy and any other materials they happen to find or lie upon. Humans cannot create food from energy because they are not producers.
Heterotrophs are organisms that eat consumers or producers. A human can eat other consumers (meat/omnivore) and eat plants (producer) like lettuce or kale.

how do ferns reproduce?
Ferns produce male and female cones.
Ferns produce spores under its leaves.
Ferns produce egg and sperms cells in the leaves.
Ferns produce flowers that contain egg and sperm cells.
Answer:
The answer is C.
Explanation:
Most ferns reproduce differently, and that involves meiosis and fertilization. When you are thinking of the typical big fern plant, what it does is, by meiosis, produces spores, and spores have half the number of chromosomes of the big parent plant. The spores are released into the wind.
Answer: The correct answer on Ody2020 is: Ferns produce spores under its leaves.
Explanation: Got it right on the assignment.
When carbohydrate consumption exceeds the body's immediate needs for energy, glycogenesis ____________ .
Glycogen storage space in the liver and muscles is limited. When glycogen stores are full, use of glucose for energy ____________ and oxidation of fat for energy ____________ .
Overall, when carbohydrate intake is excessive, lipogenesis ____________
Increase or decrease
Answer:
When carbohydrate consumption exceeds the body's immediate needs for energy, glycogenesis decreases.
The process of conversation of stored glycogen in the liver and muscles to glucose is Glycogenesis. It takes place when the blood glucose drops,below certain levels and the body cells need glucose for biochemical activities.Therefore, when there are excess CHO consumption,more glucose would be in the blood,and thus no need for glycogenesis.(breakdown of glycogen)
Glycogen storage space in the liver and muscles is limited. When glycogen stores are full, use of glucose for energy __Increases__________ and oxidation of fat for energy ___decreases_________ .
Definitely, this is a simple logic.As the storage for glycogen is limited,excess glucose move into the blood, since they can not be converted to glycogen.The glucose is expended through cellular reduce the amount in the blood. Therefore, Gluconeogenesis, the production of glucose from non-CHO substances drops. Hence beta- oxidation drops.
Overall, when carbohydrate intake is excessive, lipogenesis increases.The process of converting excess CHO to fatty acids.Biochemically it is the process of converting the Carbon precursor of acetyl co -A to fatty acids.Therefore this increases to synthesized more fatty acids from CHO

Whats the difference from the first and second law of thermodynamics
Answer:
Explanation:
the first law is the law of conservation of energy which basically means energy can't be created or destroyed in an isolated system.
the second law is that the entropy always increases in the isolated system. entropy is the measurement of the units thermal energy per unit temp.

What is its primary function of the structure of a plant cell?
Answer:Chloroplasts are organelles that are crucial for plant cell function. These are the structures that carry out photosynthesis, using the energy from the sun to produce glucose. In doing so, the cells use carbon dioxide, and they release oxygen.
Explanation:hope this helps
In all organisms, the cell is the fundamental unit of life. Plants, like animals and humans, are made up of multiple cells. The cell wall of the plant cell gives the cell its shape and covers the cell. Other organelles, in addition to the cell wall, are associated with various cellular activities.
What organelles are present in cell ?
Plant cells are eukaryotic cells that differ from other eukaryotic organisms in several fundamental ways. There is a nucleus and similar organelles in animal and plant cells. The absence of a cell wall outside of the cell membrane is one of the plant cell's distinguishing characteristics.The building blocks of plants are called plant cells. The primary function that plant cells perform is photosynthesis.The chloroplasts of a plant cell are where photosynthesis takes place. It is the way that plants use sunlight, carbon dioxide, and water to prepare food. During the process, ATP is produced as energy.Water and nutrients are transported from the roots and leaves to various parts of the plant by a few plant cells.A mature, higher plant's cells become specialized to carry out particular vital functions that are necessary for their survival. Some plant cells are responsible for storing food, while others transport water and nutrients.Parenchyma cells, sclerenchyma cells, collenchyma cells, xylem cells, and phloem cells are the specialized plant cells.To know more about cell check this:
