cholesterol is needed to build call membrane.what is cholesterol
Answers
Answer:
Answer below
Explanation:
Cholesterol refers to a group of chemical compounds. A sterol is a kind of lipid, and cholesterol is one of them. All animal cells produce cholesterol, which is an important structural component of cell membranes. It is a yellowish crystalline solid when chemically separated.
a sterol-type molecule present in most human tissues. Cholesterol and its derivatives are key components of cell membranes and precursors of other steroid chemicals, but a high proportion of low-density lipoprotein in the blood (which delivers cholesterol to the tissues) is linked to a higher risk of coronary heart disease.
Cholesterol is a waxy, fat-like molecule found in all of your body's cells. Cholesterol is required by your body for the production of hormones, vitamin D, and chemicals that aid digestion. Your body produces all of the cholesterol you require.

Answers
Given what we know, we can confirm that ready-to-eat TCS food must be date marked if it will be stored for longer than 24 hours.
What is TCS food?TCS food refers to food that must be stored in temperature-controlled environments to ensure safety.These foods, if not stored properly and at the correct temperatures can cause sickness to the consumers.Why does it need to be date-marked?The reason the foods need to be date-marked is to relay information to the potential consumer as to by when the food should be consumed. This is done to ensure that if stored correctly, the food does not have time to spoil and cause health risks for consumers.Therefore, we can confirm that ready-to-eat TCS food must be date marked if it will be stored for longer than 24 hours in order to protect the health of the consumers.

Why is it that nitrogen is often a limiting plant nutrient, despite the fact that the atmosphere is 80% nitrogen gas (N2)
Answers
Nitrogen is a limiting plant nutrient because the bulk of the available nitrogen in the atmosphere is not usable by plants.
Plants are not able to make use of the nitrogen in the atmosphere directly. Atmospheric nitrogen needs to be converted into usable forms before it can be accessed by plants.
The conversion of atmospheric nitrogen to usable form by plants is known as nitrogen fixation and this is achievable by the activities of certain bacteria.

On average, men have a basal metabolic rate (BMR) of 1.0 kilocalorie per kilogram per hour. Lawrence weighs 198 pounds. Calculate how much energy Lawrence expends for basal metabolism per day.
Answers
The energy Lawrence expends for basal metabolism per day is 2,160 kilocalories per day.
Basal metabolic rate is defined as the amount of energy that is used when an individual is at rest.
This energy is used for life sustaining functions such as:
breathing,circulation,nutrient processing andcell production.To calculate the Basal Metabolic Rate for Mr Lawrence,
Lawrence weight = 198 pounds
60
(convert pounds to kilogramme)
1 pound = 0.453592kg
198 pounds = x
xkg = 0.453592 × 198
= 89.8 kg
But BMR for average men = 1 kilocalorie per kilogram per hour.
That is, 1 kilocalories = 1 kg per hour
x kilocalories = 89.8 per day
Therefore for a day = 89.8 × 24 ( 24 hours = 1 day)
= 2155.469184
approximately. = 2,160kilocalories per day

explain the correlation between solar radiation and kelp biomass.
Answers
Given what we know, we can confirm that although sunlight is beneficial to plant growth, intense solar radiation has been proven to be detrimental to the survival of kelp, thus reducing its biomass.
How does solar radiation affect kelp?Solar radiation is not harmful in very low amounts.
However, when exposed at long intervals or high intensity, it has been shown to cause tissue damage.
This tissue damage will inhibit the kelp's ability to undergo photosynthesis.
This means it will not be able to grow, and its biomass will be reduced.
Therefore, given the effect of solar radiation in damaging the kelp's ability to photosynthesize and thus reducing its growth, we can confirm that intense or prolonged exposure to solar radiation reduces kelp biomass.

Can someone explain to me what flowering time is?? And how to control flowering time???
Answers
Answer:
Flowering time refers to the amount of time the plants will spend in the flowering stage. It begins when you switch your lights to a 12/12 schedule and ends when the buds are ready to harvest. ... In this case, the actual flowering time (as understood by most breeders) would be 2-3 weeks longer. so the flowers will spend time in differents parts of different stages
A dramatic change in the life cycle of plants is the transition to flowering, which is triggered by both environmental signals, as temperature and photoperiod, and endogenous stimuli. so it would just 2 be to watch over there environment and what u are doing 2 them
Explanation:
Answer:
Flowering time is the amount of time that a plant will stay in it's flowering stage. the flowering time of its life will reach 12 hours or less of light per day.
It's controlled by environmental conditions and development regulations, such as temperature, photoperiod and endogenous stimuli

Using the explicit formula, calculate how far the students will be swimming on week 10 using Ernest's schedule.
Answers
Ernest would be swimming at 3.25 units on week 10
The explicit formula is given as:
[tex]a_n = a_1 + (n - 1) \times d[/tex]
Also, we have the following parameters
[tex]a_1 =1.0[/tex] -- the initial distance
[tex]d =0.25[/tex] --- the difference between concurrent distances
In week 10, the value of n is 10.
Next, substitute 10 for n in the explicit formula [tex]a_n = a_1 + (n - 1) \times d[/tex]
So, we have:
[tex]a_{10} = 1.0 + (10 - 1) \times 0.25[/tex]
Subtract 1 from 10
[tex]a_{10} = 1.0 + 9 \times 0.25[/tex]
Multiply 9 by 0.25
[tex]a_{10} = 1.0 + 2.25[/tex]
Add 1.0 and 2.25
[tex]a_{10} = 3.25[/tex]
Hence, Ernest would be swimming at 3.25 units on week 10
