Individuals who lack lactase are unable to breaķ down the sugar lactose during digestion
and are said to be lactose intolerant. Which type of biomolecule is lactase?
A) protein B) lipid C) carbohydrate D) nucleic acid
Answer:
the biomolecule is something called enzymes also known as protein.
Explanation:
An enzyme that is located in our small intestine called lactase breaks down the lactose into two parts. Only after the two sugars (glucose and galactose) have been separated can then they be absorbed by our bowel.
Compare the Viking 1 and 2 probes to the Pathfinder probe that landed on Mars in 1997. How was their technology different?
Answer:
Explanation:
In 1976, The Viking 1 and Viking 2 probes landed on Mars. For six years they transmitted fascinating panoramic views of the red and rocky soil of Mars back to Earth. Twenty years passed before a third probe landed on Mars. In 1997, the Pathfinder probe landed a miniature vehicle named Sojourner on the planet. The probes operated for three months and sent back large amounts of data on the Martian environment. At the same time, the Mars global surveyor probe was placed in orbit to take an overall portrait of the planet. It supplied hundreds of thousands of bits of information, especially on climatic variations.
Answer:
Viking 1 and Viking 2 probes transmitted panoramic views of the red and rocky soils back to Earth after six years later. The Pathfinder probe sent back large amounts of data of the environment especially about climatic variations in only three months. You can tell the technology was very different between these two because of how long it took for each probe to gather data.
One of the buffers that contribute to pH stability in human blood is carbonic acid (H2CO3). Carbonic acid is a weak acid that, when placed in an aqueous solution, dissociates into a bicarbonate ion (HCO3-) and a hydrogen ion (H+).
Thus, H2CO3 = HCO3- + H+
If the pH of the blood increases, one would expect:
(A) a decrease in the concentration of HCO3- and an increase in the concentration of H+
(B) an increase in the concentration of H2CO3 and a decrease in the concentration of HCO3-
(C) a decrease in the concentration of H2CO3 and an increase in the concentration of HCO3-
(D) an increase in the concentration of HCO3- and a decrease in the concentration of OH-
(E) a decrease in the concentration of HCO3- and an increase in the concentration of both H2CO3 and H+.
I'm not sure if it is C or D
Answer:
The answer is "Option C".
Explanation:
In the given question, the pH scale is used to evaluate acid or basic (alkalinity) formulas. It is nearly positive throughout the blood. Human blood has to maintain its pH at about 7.4, to prevent dramatically increased or lower changes, even though the bloodstream enters or exits acidic or essential substances.
The buffers are essential for stabilization management. Calcium carbonate produced as carbon dioxide joins the blood system and combines with the liquid is a buffer which adds to the pH level in the human blood. It is returned to the water and distributed as a waste product until it enters the lungs, that's why choice C is correct.WILL GIVE BRAINLIEST!!!!!!!!
After a forest fire what would be the first change in a forest?
Pioneer species are established
A climax community is established
Wind carries seeds to the area and plants grow from these seeds
New soil forms from rock
c because
The first plants to move into the new bare ground after a wildfire are wildflowers or “weeds.” These fast-germinating, leafy herbaceous plants are also known as “forbs” or “ephemerals.” They quickly germinate, grow and produce a new crop of seeds.
Answer:
Pioneer species are established
Explanation:
A forest fire would represent the process of secondary succession.
In secondary succession, the first stage is the growth of pioneer species. The soil still remains, so no new soil needs to be made.
This rich soil allows for pioneer species to grow in the forest.

what is the point on an object where the force of gravity is considered to act A. center of mass B. top of an object C. middle of the object D. center of gravity
Answer:
D. Center of gravity.
Explanation:
Gravity always acts downward on every object on earth. Gravity multiplied by the object's mass produces a force called weight. Although the force of an object's weight acts downward on every particle of the object, it is usually considered to act as a single force through its balance point, or center of gravity.
Answer:
D. center of gravity

Explanation:
A city is supplied by water from local wells. The city discharges its treated wastewater into the ocean.The city uses 25,000 liters of water per person per year. Precipitation falls in the amount of 25,000 liters per person per year.
Is the city using its water supply in a sustainable manner?
A)yes
B)no
Answer:
B)no
Explanation:
Sustainable use of water means use of water to fulfil various human needs for water without having any negative impact on the environment.
The sustainable use of water allows a minimum of 20 to 50 litres of daily water per person to fulfil their water needs, that means 600 litres maximum per person per year but in the given situation the city uses 25,000 litres of water per person per year.
This shows that people in the city are not using water sustainably which is causing a fall in precipitation.
Hence, the correct answer is "No".

Energy can be measured in calories, 1,000 calories is called a kilocalorie (kcal),
If the producers have 10,000 kcal of energy and 10% is transferred to the primary
consumers, how much energy is transferred?
100 kcal
1,000 kcal
10 kcal
Plz help me which one is it!!!!!
Answer: 1,000kcal
10% of 10,000 is 1,000.
The amount of energy transferred if 10% is transferred to the primary consumers is 1000kcal
Given the following parameters
Amount of kcal the producer have = 10,000kCal
Percentage transferred to the primary consumers = 10% of the amount produced
Get the amount of energy transferred;
[tex]Energy \ transferred = \frac{10}{100} \times 10,000\\ Energy \ transferred =0.1 \times 10,000\\Energy \ transferred =\frac{10,000}{10}\\Energy \ transferred =1000kcal[/tex]
Hence the amount of energy transferred if 10% is transferred to the primary consumers is 1000kcal.

What is the role of photosynthesis and cellular respiration in the cycling of matter and the flow of energy through the ecosystem
Answer:Cellular respiration in plants and animals involve chemical reactions with oxygen that release stored energy. ... Plants, algae, and many microorganisms use the energy from light, carbon dioxide from the atmosphere, and water to make sugars (food) through the process of photosynthesis, which also releases oxygen.
Explanation:
hope it helps :)
The role of photosynthesis and cellular respiration in the cycling of matter and the flow of energy through the ecosystem is the following:
The fundamental energy source of all ecosystems is the Sun, which sends a large amount of energy to Earth in the form of light and heat.
The various green plants use energy from the sun, water and nutrients from the soil, and carbon dioxide from the air to produce organic matter.
The process by which light is used as an energy source to transform CO2 into organic compounds essential for life is called photosynthesis.
The manufactured organic matter is used by the photosynthetic organisms themselves for the maintenance of their vital processes through cellular respiration.
Energy, once solar energy is transformed by producers into chemical energy by making organic matter in photosynthesis, is transmitted along with matter.
In each transfer of energy, between the different types of organisms there is a release of energy to the environment, in the form of heat.
On the contrary, matter flows cyclically, chemical elements are transferred between living beings and in the physical environment of each ecosystem.
Therefore, we can conclude that the role of photosynthesis in the cycling of matter and the flow of energy through the ecosystem is to produce the transformation not only of inorganic into organic matter, but also of light energy into chemical binding energy, oxygen is released as a waste product and is used by most organisms for cellular respiration.
