The acidic chyme entering small intestine is neutralized by the bile.

Which of the following geological features could form when two plates collide?
A. Trench
B. Mid-Ocean Ridge
C. Transform fault
D. Delta
Answers
Answer:
trench
Explanation:
Trenches are geological features formed by convergent boundaries. When two tectonic plates converge, the heavier plate is forced downward, creating a subduction zone. This process results in the formation of a trench. The Marianas Trench is an example of a trench formed by the convergence of two oceanic plates. The deepest part of this trench, called the Challenger Deep, is over 36,000 feet deep, deeper than Mount Everest is tall.
what act as a root in the pteridophytes
Answers
Answer:
The root system is always adventitious. The stem is either underground or aerial. The leaves may be microphylls or megaphylls. Their other common characteristics include vascular plant apomorphies (e.g., vascular tissue) and land plant plesiomorphies (e.g., spore dispersal and the absence of seeds).
Explanation:
Answer:
A pteridophyte is a vascular plant that disperses spores. Because pteridophytes produce neither flowers nor seeds, they are sometimes referred to as "cryptogams", meaning that their means of reproduction is hidden. Ferns, horsetails, and lycophytes are all pteridophytes. However, they do not form a monophyletic group …

What stimulates a skeletal muscle cell to contract?.
Answers
During the early days of deciphering the human genome, scientists were surprised to find that the number of genes appeared to be significantly fewer than what had been predicted on the basis of the estimated numbers of different proteins required by our cells. What aspect of nucleic acids and transcription can help explain this discrepancy?.
Answers
Given what we know, we can confirm that the aspect of nucleic acids and transcription that can help explain this discrepancy is that of alternative splicing.
Alternative Splicing.This process allowed the cells to use a single gene for the creation of various proteins. This process includes the separation of RNA at splicing sites to create new versions of the mRNA strand.This helps to increase the diversity of mRNA's available and create more proteins.Therefore, given that alternative splicing allows the cells to create multiple forms of distinct proteins from a single gene, this allowed our organisms to develop the vast number of proteins we use, without the need for a much larger genome.

A clade is a fancy word for any group in a phylogenetic tree that includes an ancestor and all of its descendants. A simplified dinosaur tree is below.
Imagine that you have a pair of scissors and can cut the tree. You can tell a group is a clade because it would only take one “snip” to make the group “fall off” the tree. Five different clades have been marked on the tree with brackets. The clade marked 1 is clade Aves—the birds. The clade marked 2 is clade Theropoda—the theropods. Clades 2 and 3 are the two major groups of dinosaurs—clade Saurischia and clade Ornithischia. Finally, clade 5 is clade Dinosauria—the dinosaurs.
Triceratops belongs to two of the marked clades on this tree: 4 and 5. This means that Triceratops is both an ornithischian (clade 4) and a dinosaur (clade 5). Which clades do birds belong to? (Select all correct answers)

Explanation:
Birds can be dinosaurs, but not ornithischians. Birds can also be Saurischia and class 1.
The classes that birds belong include 5 (Dinosauria), 2 (Saurischia), 3 (Ornithischia), and 1 (Aves).
What is a clade?A clade is an evolutionary taxonomic group that exhibits a common ancestor in a given lineage.

Explanation:
Because selection is a process in which environmental influences determine which type of
organism thrive better than other, regarded as a
factor of evolution.
The bird eating the white moth is the illustrated as the process of selection and the process of reproduction also takes place. Thus, option D is correct.
What is reproduction?
Reproduction has been defined as the process carried out by the living organisms and during the process of reproduction the living organisms produces their own young ones and feed them. Reproduction has been the supreme quality of the living things.The process of the reproduction in which two parents are involved has been said to be sexual mode of the reproduction and the process of reproduction in which only single parent has been involved in the known as asexual mode of the reproduction.
There are two types of the reproduction and these are the sexual and asexual reproduction. The process of the reproduction in which two parents are involved has been said to be sexual mode of the reproduction and the process of reproduction in which only single parent has been involved in the known as asexual mode of the reproduction. Reproduction has been the supreme quality of the living things.The example of the asexual reproduction are budding, fragmentation, spore formation, and binary fission.
