Answer:

Keratin has two main functions: to adhere cells to each other and to form a protective layer on the outside of the skin. In epithelial cells, keratin proteins inside the cell attach to proteins called desmosomes on the surface. The desmosomes act as anchors, holding the cells together.

In muscle cells, fermentation produces _____.
algol13

Answer:

The correct answer is E. Lactate and NAD+

Explanation:

Fermentation occurs in anaerobic condition and in humans, most of the energy is provided by aerobic respiration but when the body needs a lot of energy in a very quick time like in sprinting then muscles use lactic acid fermentation to gain energy.

After the consumption of all stored ATP during intense work, our body starts lactic acid fermentation to gain ATP. In lactic acid fermentation, the pyruvate molecule that was produced during glycolysis is converted into lactate molecule. In this process, NADH is oxidized to NAD+.  

Therefore in lactic acid fermentation lactate and NAD+ are produced. So the correct answer is E.

Two unlabeled slides are viewed under a microscope. Slide A has cells with a visible nucleus, mitochondria, a cell membrane, a c
Travka [436]

Answer:

C. Slide A, plant cells; Slide B, animal cells

Explanation:

The slide A has some organelles that are unique to plant cells, and are mostly found in plant cells. Organelles such as a cell wall and chloroplasts are unique features of plant cells. They are normally absent in animal cells.

Therefore, slide A, which has these cell organelles can be rightly labelled as "plant cells", while side B, which has these organelles missing, can be labelled as "animal cells".

Irina-Kira [14]

Cells are the smallest unit of life. This is true.

Cells are important to the structure and function of living things. This is true.

All organisms are made of multiple cells. This is false, because there are many single celled organisms like bacteria.

Cells come in different shapes and sizes. This is true, as there are cells with a variety of shape and size (round shaped cocci and the elongated and flat bacillus). There are cells from squid's nervous system, called the neurons, that are comparatively very large in size than the vast majority of the other cells.

Which food molecule (monosaccharide, polysaccharide, lipid, or protein) would you eat if...
torisob [31]
<span>You needed a quick boost of energy - MONOSACCHARIDE

You wanted to grow strong nails, you haven't eaten in days - PROTEIN

You wanted to grow healthy hair - PROTEIN

You had a race tomorrow afternoon - POLYSACCHARIDE 

You were getting ready for hibernation - LIPIDS

You wanted to get bigger muscles - PROTEIN 

Your meal will be in a week - LIPIDS

CARBOHYDRATES include monosaccharide and polysaccharides. They provide immediate energy boost or short term energy storage for animals as well as long term energy storage for plants. 

PROTEIN s</span>peeds up chemical reactions by lowering activation energy. It is used to form bones and build muscles. It is m<span>ade up of an amino group, a carboxyl group, and an R group.

LIPIDS can be saturated or unsaturated fatty acids. They are not soluble in water however they provide long-term energy storage for animals. </span>
