Answers
Answer:
Main sequence, red giant, white dwarf.
Explanation:
The life cycle of the sun is called as solar cycle and is the phase of solar development. There are about seven-stage in its life cycle. Starting with the birth of the sun that is found in the solar nebula theory took place about 4.56 billion years. The sun starts to enter the T Tauri stage, followed by the main sequence stage where the sun is currently in. After this stage that is when the sun runs out of hydrogen from its core. It will produce violent helium flashes and will shrink its size. When this happens it will reach the tip of the red giant stage. Later on, the naked core will form into a white dwarf.Please help me with this question. Biodiversity needs to be maintained for the future of the human race.

Answer:
What is biodiversity?
It is the variety of life on Earth, in all its forms and all its interactions. If that sounds bewilderingly broad, that’s because it is. Biodiversity is the most complex feature of our planet and it is the most vital. “Without biodiversity, there is no future for humanity,” says Prof David Macdonald, at Oxford University.
The term was coined in 1985 – a contraction of “biological diversity” – but the huge global biodiversity losses now becoming apparent represent a crisis equalling – or quite possibly surpassing – climate change.
More formally, biodiversity is comprised of several levels, starting with genes, then individual species, then communities of creatures and finally entire ecosystems, such as forests or coral reefs, where life interplays with the physical environment. These myriad interactions have made Earth habitable for billions of years.
A more philosophical way of viewing biodiversity is this: it represents the knowledge learned by evolving species over millions of years about how to survive through the vastly varying environmental conditions Earth has experienced. Seen like that, experts warn, humanity is currently “burning the library .

HELPPPPP PLZ NEED IT BY TODAY PLLZZZZZZ 10 PIONTS
Answers
Answer:
delta
Explanation:
deltas take time to cause changes in the earth's surface as it takes time for water to erode and change things. volcanoes takes minutes to burn and ruin anything in its path, and landslides destroys everything in its path as well immediately.
A rapid or fast change can be defined as one that occurs quickly within a short amount of time.
Among the given example of changes, the types of changes are as follows:
Landslides - It is a result of imperceptive downslope movement and can occur within 10 seconds.Volcanoes - The eruption of volcanoes takes only a few seconds.deltas - The slow and steady flow of rivers form deltas and may take up to thousands of years.Earthquakes - It occurs within a few seconds after the fault ruptures and the ground shakes.Thus, the change that is not rapid is the formation of deltas.

Distinguish between an acid and alkaline slant?
Answers
Answer:
Acid slant: yellow, fermentation of glucose and lactose and/or sucrose. High concentration creates excessive acid formation
Alkaline slant: red, limited glucose in the medium and limited acid formation.
The pH of acids is less than 7. Alkalis have a pH more than 7 The pH of neutral substances is 7. If metal oxides are soluble in water, they are alkaline. Non-metal oxides are acidic, if soluble in water.
What are acids?An acid is a molecule or ion that can either donate a proton (Bronsted-Lowry acid) or form a covalent bond with an electron pair (Lewis acid). The proton donors, also known as Bronsted-Lowry acids, are the first type of acid.
Only dextrose fermentation produces an alkaline/acid (red slant/yellow butt) reaction.
The fermentation of dextrose, lactose, and/or sucrose is indicated by an acid/acid (yellow slant/yellow butt) reaction.
An alkaline/alkaline reaction occurs when as a result, carbohydrate fermentation does not occur.
The presence of red (alkaline) in the slant and butt indicates that the organism being tested is a nonfermenter.
The formation of hydrogen sulfide results in a black precipitate in the butt of the tube. The splitting and cracking of the medium indicates gas production.
Thus, these are the basic difference between acid and alkaline slant.

A researcher performs an experiment to test a hypothesis that involves the nutrients niacin and retinol. She feeds one group of laboratory rats a daily diet of precisely 125.6 units of niacin and 5,400 units of retinol. She uses two types of commercial pellet food. Food A contains 0.86 units of niacin and 30 units of retinol per gram. Food B contains 0.66 units of niacin and 40 units of retinol per gram. How many grams of each food does she feed this group of rats each day
Answers
Answer:
- 100 grams of food A (x)
- 60 grams of food B (y)
Explanation:
According to this question, the group of laboratory rats are being fed a daily diet of:
- 125.6 units of niacin and 5,400 units of retinol
Let x represent the number of grams needed for food A.
Let y represent the number of grams needed for food B.
This means that:
Food A: Niacin = 0.86x, Retinol = 30x
Food B: Niacin = 0.66y, Retinol = 40y
Since there are 125.6 units of niacin fed to the rats in total, then;
0.86x (A) + 0.66y (B) = 125.6
Since there are 5400 units of retinol fed to the rats in total, then;
30x (A) + 40y (B) = 5400
Solving these two equations simultaneously using elimination method:
0.86x (A) + 0.66y (B) = 125.6 ........(eqn 1)
30x (A) + 40y (B) = 5400 ............ (eqn 2)
Multiply eqn 1 by 30 and eqn 2 by 0.86
30 × 0.86x + 0.66y = 125.6
0.86 × 30x + 40y = 5400
25.8x + 19.8y = 3768 ............ (eqn 3)
25.8x + 34.4y = 4644 ........... (eqn 4)
Subtract eqn 3 from eqn 4
14.6y = 876
Divide both sides by 14.6
y = 876/14.6
y = 60
Substitute value for y (60) into eqn 2
30x + 40y = 5400
30x + 40(60) = 5400
30x + 2400 = 5400
30x = 5400 - 2400
30x = 3000
x = 3000/30
x = 100
Therefore, she feeds the group of rats 100grams of food A (x) and 60 grams of food B (y).
Cilia are involved in the transfer The genetic information from one bacterial cell to another

False.
Explanation:
No, Cilia are not involved in the transfer of the genetic material from one bacterial cell to another. The pili are the structure which is responsible for the transfer of genetic material from one bacteria to another. This transfer can only occur for those types of bacteria that possess a special plasmid that is responsible for the formation of pilus which leads to the transfer of genetic material. If the special plasmid is not present so there will be no tranfer of genetic material from one bacteria to another.

Understanding Dose vs Exposure
John works applying pesticide X to agricultural fields. He spent the morning cleaning out a tank that had contained concentrated pesticide X. The tank was large and he was standing in water all morning (4 hours) power washing the tank. Human skin is a wonderful barrier to entry of compounds as long as it is dry and intact, but wet wrinkly skin can absorb toxins. About 5% of pesticide X absorbs into wet skin and John was in contact with water that had a total of 32 g of the pesticide in it.
After the morning is over, John has lunch but does not wash his hands; he has 2 g of the pesticide on his hands. Pesticide X has about 90% absorption from an oral dose.
Finally, John works in the field in the afternoon a crop plane flies over dusting the crops with pesticide X, the air he breathes in has a total of 5 grams of the compound in it. Pesticide X is known to have absorption of about 50% through inhalation.
What is John’s exposure to Pesticide X and what is his dose?
Route of Exposure Exposure (grams) Dose (grams)
Dermal
Oral
Inhalation
Total
Looking at the total exposure and dose, what percentage of his exposure was a dose?
Answers
Answer:
The correct answer is - 15.13%
Explanation:
According to the question, the exposure of the pesticide X to the skin of John is by different routes and amount of the exposure is given and the percentage value is calculated as well:
Route of exposure --- exposure in gram---Dose in gram
Dermal ------------------------32-----------------------32*5/100= 1.6
Oral------------------------------2-----------------------2*90/100= 1.8
Inhalation----------------------5-----------------------5*50/100= 2.5
Total --- -----------------------39 -----------------------5.9
On the basis of this, the exposure is mainly by inhalation, the total exposure is about 39 grams about 5.9 percent. However,
The percentage of dose exposure = (5.9/39)*100
= 15.13%

Which class of Lever is being described if you are standing on tiptoes and if: The Fulcrum is at the metatarsal and phalanges, which is at one end of this lever on the anterior side of the body. The Load is your body weight which is in the middle of this lever. The Effort is exerted by the gastrocnemius and soleus muscles at the calcaneal (Achilles') tendon on the other side of this lever on the posterior side of the body.
Answers
Answer:
Second class lever
Explanation:
A second class lever is when the resistance ( load/weight ) is placed in between the axis ( Fulcrum which is formed by the metatarsal and Phalanges ) and the force ( Achilles tendon ) that is applied to the lever. hence the class of lever being described is a second class lever
There are three classes of lever ( 1st class, 2nd class and third class ) but The most common lever found in Humans are the 3rd class levers. but standing on tiptoes by an individual is a perfect example of a 2nd class lever found in a Human.
The Load being the body weight being and in the middle of this lever is
referred to a the second class lever.
The second class lever has the load in between the effort (force) and the
fulcrum. A common example is the wheelbarrow which has the load in the
middle.
In this scenario, the load which is the body is between the
effort(gastrocnemius and soleus muscles) and the fulcrum is the phalanges
which is a characteristic of a second class lever.
