lactose
Answer:
A lactose tolerance test measures how well your body can process lactose, a type of sugar found in dairy products. Normally, the body is able to process milk and other dairy products thanks to an enzyme in the intestines called lactase, which breaks down lactose during digestion.

What needs to change so that only the green solutes diffuse across the membrane?
What need to be changed is ; The use of selectively/semi-permeable membrane
To selectively allow the passage ( diffusion ) of a certain type of solute through a membrane in a solution, we should make use of a selectively permeable membrane which allows only the passage of a certain type of solute contained in the solution ( like the green solutes ).
The use of permeable membrane in a solution is to selectively allow flow of solutes or solvent from a region of lower concentration to a region of higher concentration.
Hence we can conclude that what needs to be change is The use of selectively/semi-permeable membrane will allow only the green solutes to diffuse across.

d. are more versatile than fossil fuels
C.
Answer:
are only replenished with human intervention are renewable
Renewable alternative energy sources like solar and wind power only need human interaction to refill themselves. As a result, choice B is the right one.
Alternative energy sources are ways of producing energy that are more environmentally responsible, renewable, and sustainable than conventional fossil fuels like coal, oil, and natural gas. The significance of creating and utilising alternative energy sources has increased as concerns over the depletion of non-renewable resources and the effects of climate change become more and more apparent. Numerous alternative energy sources are being investigated and used globally due to technological breakthroughs and rising global awareness.

I need answers only in points for my lil sis, otherwise i'll report it..I'll reward brainliest to correct answer.
Answer:
Darwin's theory of evolution state that"all species of organisms arise and develop through the natural selection of small, inherited variations that increase the individual's ability to compete, survive, and reproduce".
Answer:
Charles Darwin's theory of evolution states that evolution happens by natural selection. Individuals in a species show variation in physical characteristics. Individuals that are poorly adapted to their environment are less likely to survive and reproduce.Chickens that carry both the alleles for rose comb (R) and pea comb (P) have walnut combs, whereas chickens that lack both of these alleles (that is, rr pp) have single combs.

How are traits inherited by offsring?
Answer:
Traits are passed to offspring by the offspring parents.
Explanation:
the genes that control a trait come in pairs, one from each parent. If a gene pair contains a dominant allele (a variation of genes that will produce phenotype,) than the offspring gains that trait from the dominant parent.

Which dinosaur most likely evolved from Coelophysis?Immersive Reader
(5 Points)
Camptosaurus
Triceratops
Theodont
Tyrannosaurus
Answer:
camptosaurus
Explanation:
I think it's correct
The Dinosaur that most likely evolved from Coelophysis is known as Camptosaurus. Thus, the correct option for this question is A.
What is Evolution?Evolution may be characterized as the complete methodology of gradual change that takes place over many generations, during which species of animals, plants, or insects slowly change some of their physical characteristics.
Coelophysis lived during the late Triassic period some 216.5 to 203.6 million years ago. Researchers believe that this small theropod lived on river floodplains where it walked alongside crocodilian-like Camptosaurus. They were small theropod dinosaurs that lived in what is now North America and Southern Africa during the late Triassic.
Therefore, the Dinosaur that most likely evolved from Coelophysis is known as Camptosaurus. Thus, the correct option for this question is A.

Which of the following is not one of Mendel's Laws?
a) Law of Conservation of Mass
b) Law of Segregation
c) Law of Dominance
d) Law of Independent Assortment
Answer:
A
Explanation:
Law of conservation of mass was discovered by Lavoisier
Law of Conservation of Mass is not one of Mendel's Laws. Therefore, the correct option is A.
What are Mendel's Laws?Gregor Mendel's research with pea plants in the 19th century led him to reveal three fundamental laws of inheritance, known as Mendel's laws. There are three laws:
1. Law of Segregation: Each individual has two alleles for each trait, and this law indicates that these alleles separate (separate) during the development of gametes, or reproductive cells. This indicates that only one allele per trait is present in each gamete.
2. According to the law of independent assortment, the inheritance of one trait is independent of the inheritance of another. In other words, the segregation of alleles for one trait is independent of the segregation of alleles for the other trait.
3. The law of dominance states that when two different alleles are present in an individual, the dominant allele will dominate the recessive allele in terms of expression. Only when both alleles are recessive will the recessive allele be expressed.
Therefore, the correct option is A.

type of nutrition shown by all fungi
Fungi cannot produce their own food like plants can, nor can they consume it like animals can. Instead, fungi get their nutrition by absorbing it from their surroundings.
What is fungi ?Eukaryotic creatures known as fungi include yeasts, molds, and mushrooms as well as other microbes. These organisms fall under the category of fungus. The creatures that make up the Kingdom Fungi are pervasive and have a cell wall. They fall under the category of heterotrophs among living things.
Both varieties of fungi emit digestive enzymes into the nutrient surface they are growing on in order to feed. Proteins and carbohydrates are broken down by the enzymes and then absorbed through the walls of the hyphae.
All fungi are heterotrophic, which means they draw their energy from other living things. Like animals, fungi draw energy from live or dead organisms through the bonds of organic substances like sugar and protein.
Thus, Fungi cannot produce their own food like plants can, nor can they consume it like animals can.

What is NOT a function of the reticular formation?
a. sleep b. breathing c. memory d. pain transmission
Answer:
c. memory
Explanation:
Memory is not a function of the reticular formation. Sleeping, breathing, and pain transmission all are the functions of reticular formation. Thus, the correct option is C.
What is reticular formation?
Reticular formation is a part of the pons region of brain which controls the sleep-wake cycle and also filters stimuli to separate out relevant background stimuli from irrelevant ones.
Reticular formation is one of the phylogenetically earliest parts of the brain and it is crucial for controlling some fundamental processes such as sleeping, breathing, and pain transmission.
The reticular formation is an essential process for the numerous activities of the brainstem. It is located strategically amid the significant nuclei in the brain cells and the nerve fibers that traverse it. The reticular formation looks like an intricate web network.
Therefore, the correct option is C.
