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.What molecule are we testing for to determine if the milk was properly digested?
Question 11 options:
galactose
lactase
glucose
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 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.

Tall (T) is the dominant allele in pea plants, while short (t) is recessive. Which are the genotypes of a tall plant?
Help!!!!!
Answer:

Explanation:
A dominant always masks a recessive characteristic in a genotype, so Tt is a tall plant. TT has two dominant traits, so it is also tall.
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.

Explanation:
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. From the information about interactions between these two genes, determine the phenotypes and proportions expected from the following crosses:
a. RR Pp × rr Pp;
b. rr PP × Rr Pp;
c. Rr Pp × Rr pp;
d. Rr pp × rr pp

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.

Flower diameter in sunflowers is a quantitative trait. A plant with 6-cm flowers, from a highly inbred strain, is crossed to a plant with 30-cm flowers, also from a highly inbred strain. The F1 have 18-cm flowers. F1 × F1 crosses yield F2 plants with flowers ranging from 6 to 30 cm in diameter, in approximately 4-cm intervals (6, 10, 14, 18, 22, 26, 30).

The chart below shows the inferred evolution of some dinosaurs during three time periods in Earth’s history.
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.
