What is a distinction that can be drawn between macroevolution and microevolution?

nikitadnepr [17]

Microevolution refers to changes in the genetic pool of a species population. The changes in the genes (probably gene and allele frequencies) are observed over short time periods hence are small changes. This is in comparison to macroevolution that observes huge changes over longer time periods in the population that warrant that the new populations is considered to be a new species

Few seeds can be dispersed by more than one method of seed dispersal.’ Explain with suitable examples.

MrMuchimi

Answer:

There are five main modes of seed dispersal: gravity, wind, ballistic, water, and by animals. Some plants are serotinous and only disperse their seeds in response to an environmental stimulus.

Gravity: A good example of gravity dispersal is the marigold flower. When they are ready, these seeds drop to the ground.

Wind: There are two types of wind dispersal adaptations, the floaters, and the fliers:

(wind) Floaters: The common dandelion is a good example of this type of seed dispersal.

(wind) Fliers: Maple seeds grow in pairs, but when they are mature, they separate, and a strong wind can pull them from the stem

Ballistic: Some common examples of this type of dispersal are garden peas. When the cells grow older, the result is that the pods break open and twist. This twisting actions pops the seeds lose and pushes them away from the pod.

Water: Coconuts have a husk that surrounds the seed. This husk is very buoyant and a coconut seed can float across hundreds of miles of ocean before washing ashore on a new island to germinate and grow into a tree.

Animals: there are also two types of these, hitchhikers and edibles. Seeds that stick to the outside of animals, or are spread when they go out the other end after being eaten:

Hitchhikers: Some examples are cockleburs and foxtail.

Edibles: These seeds are surrounded by good tasting fruit, like apples and peaches.

Please help to solve this question.

erica [24]

Answer:

a. Glycolysis

b. actually, both plants and animals use glycolysis. They use these during cellular respiration and plant respiration

c. Heart tissue!

Explanation:

a. Glycolysis produces 2 ATP per glucose molecule, and thus provides a direct means of producing energy in the absence of oxygen. Lactic acid, the end product of anaerobic glycolysis.

b. In organisms that perform cellular respiration, glycolysis is the first stage of this process. In plants, this metabolic process occurs in the cytosol and plastids of both photosynthetic and non-photosynthetic organs.

c. Pyruvate is an important chemical compound in biochemistry. It is the output of the metabolism of glucose known as glycolysis. In highly oxidative tissue, such as the heart, the production of pyruvate is essential for acetyl-CoA synthesis and L-malate synthesis.

Hope this helps! If you could, please mark this as brainliest :)

1. Describe the pattern of air circulation between an

maw [93]

Answer:

The sinking of cold air creates regions of high pressure and this air travels to lower pressure regions produced by the rising motion of warm air. This process results in air circulation.
