How do you think your food sources compare to the breakdown

Biology
2 answers:
uysha [10]3 years ago
5 0

Answer:

What we eat matters. The food choices we make every day have a big effect on the environment. The good news is that even small changes in what we buy and eat can add up to real environmental benefits, including fewer toxic chemicals, reduced global warming emissions, and preservation of our ocean resources.

Answer:

Cells manage a wide range of functions in their tiny package — growing, moving, housekeeping, and so on — and most of those functions require energy. But how do cells get this energy in the first place? And how do they use it in the most efficient manner possible? Cells, like humans, cannot generate energy without locating a source in their environment. However, whereas humans search for substances like fossil fuels to power their homes and businesses, cells seek their energy in the form of food molecules or sunlight. In fact, the Sun is the ultimate source of energy for almost all cells, because photosynthetic prokaryotes, algae, and plant cells harness solar energy and use it to make the complex organic food molecules that other cells rely on for the energy required to sustain growth, metabolism, and reproduction.

Describe continental drift and plate tectonics. How can these affect the evolution of different plant and animal species?
almond37 [142]

Explanation:

As tectonic plates drift due to the convection currents of the mantle below, so does the climate on the tectonic plates. This is because the drift causes the continents to glide across latitudes. Different latitudes have different climatic conditions associated with them. An example is an equatorial climate in the equator, the subtropical climate in the mid-latitudes and polar climate in the polar region.

Therefore, even though this drift is happening very slowly over millions of years, the plant and animal species in these continental also slowly adapt to the changing climatic condition in their environment associated with these continental drifts.

the galapagos tortoise are biodiverse. tortoises in a more barren area have a flat shell and long neck to help grasp the sparse
natima [27]

Answer:

<em>This is an example of natural selection (adaptation).</em>

Explanation:

Natural selection tends to favor those organisms which are better adapted to live in an environment.

As tortoises having flat shell and long neck were better adapted to live in barren area, hence through natural selection those organisms were favored in such an ecosystem.

As tortoises that lived on the vegetative lands were more adapted to live in such an ecosystem, hence through natural ecosystem these organisms were favored and increased in numbers.

List the five classes of antibody heavy chains and provide one function for each.
Lesechka [4]

Answer:

IgM, IgA, IgE, IgD and IgG

Explanation:

IgM functions in the initial response to offence.

IgA is important for protection of mucus membranes such as in saliva, sweat, tears and gastric fluid.

IgE is active during allergic reactions and defense against infections.

IgD is found on the surface of lymphocytes and is activated upon contact with antigens.

IgG forms part of the secondary response to antigen and is also responsible for newborn protection.

Why is salivary amylase active for only an hour or so, whereas lingual lipase isn't active until reaching the stomach
leva [86]

Salivary amylase will be active for only an hour or so because the optimum pH for activity of amylase is about 6.7–7.0 which is available in the mouth but the pH of the stomach is acidic around 1-2 due to which the amylase enzyme becomes inactive in short-time.

The lingual lipase enzyme is present in the saliva but isn't active until reaching the stomach because this enzyme is acid stable and works efficiently in the stomach, not in the mouth.

Amylase enzyme is secreted in the mouth and is responsible for the breakdown of starch in food into sugars and it starts acting as soon as we put food in the mouth whereas Lingual lipase enzyme is secreted along with saliva but it is not active in the mouth rather its activity starts in the stomach which is responsible for the degradation of triacylglycerol molecules.
