Which would have the GREATEST effect on the rate of photosynthesis in a plant? A) oxygen level B) light intensity C) sugar concentration D) starch concentration

Answers

Answer 1

Answer:

The correct answer is option B, Light intensity

Reason -

Light intensity plays a major role in the regulation of photosynthesis. In the absence of light a plant is unable to photosynthesize. As the plant receives light through the chlorophyll , essential chemical reactions takes place thereby releasing free electrons which keep on driving the further processes or reactions in a plant to produce food and oxygen and energy..

The higher the light intensity, the higher is the rate of photo synthesis

Answer 2

Answer: Oxygen levels make no impact, they need CO2.
Sugar concentration makes no impact as that is a product.
Starch makes no impact.
Only light from the choices above is the factor in photosynthesis that could have the greatest effect as it is not a product yet a reactant

Resistance of the skin to invading organisms is __________.a. acquired immunity
b. humoral immunity
c. cellular immunity
d. innate immunity

Answers

The correct answer is (d.) innate immunity. The resistance of the skin to the invading organism is innate immunity. The innate immunity is comprising of the cells and mechanism for defending the body from pathogens. The cells recognize and respond to the pathogens that is acting to enter the body.

Label each example as either (PI) passive or (AI) active immunity:a. ________ Bill had chicken pox when he was five. He doesn’t catch it again, even when his nephew gets sick with the virus.
b. _______ Billy Jr gets vaccinated with a live attenuated form of the chicken pox virus. He doesn’t get chicken pox after playing with his infected cousin.
c. _______ Bill’s 3 month old daughter is breast feeding. She does not get chicken pox after playing with her infected cousin.

Answers

First, let's distinguish active from passive immunity:
- Active immunity occurs in a direct exposure of individuals to live pathogens. The result is a development of a disease. After that, individuals acquire immunity to the disease.
- Passive immunity is induced by vaccines with antibodies for a disease, so the disease does not develop.

a. ACTIVE IMMUNITY - Bill had a disease, so it must be active immunity.
b. PASSIVE IMMUNITY - Bill got a vaccine and a disease did not develop, so it must be passive immunity.
c. PASSIVE IMMUNITY - Although, 3-month-old daughter did not get a vaccine, she has mother's antibodies from the milk so she will not develop a disease.

Answer:

Active

Passive

Which of the following is a not component of lipids?carbon chains
nucleotides
fatty acids
glycerol

Answers

Nucleotides are not a component of lipids.

WHAT ARE LIPIDS:

Lipids are one of the four biomolecules we have in nature. Structurally, lipids are made up of monomers called FATTY ACIDS and GLYCEROL.

Each of these monomers are made up of long chains of carbon, meaning that lipids also have long chains of carbon.

However, nucleotides are monomers of another biological molecule called nucleic acids and hence, cannot be a component of lipids.
