Which organs perform both mechanical digestion and chemical digestion of food?
Answer:
stomach
Explanation:
stomach churns the food (mechanical digestion) and the enzymes in the hydrochloric acid perform the chemical digestion part.
i believe mouth also does the same because it technically chemically digests with the enzyme amylase in the saliva but the overall answer is stomach.

A man who heavily smokes has developed lung cancer. The tobacco smoke has caused mutations in some of the cells in his lungs, making them unable to stop reproducing and dividing. He is worried that his children, none of whom smoke, may have inherited the lung cancer from him. Under what circumstances might his concern for his children be justified? If his smoking had already mutated the DNA in the cells in his lungs at the time his children were conceived, the mutations would have been passed to his children. If he inherited a mutation which made him more susceptible to lung cancer, it may have been present in some of the gametes he produced and passed to his children. If the mutation resulted from the duplication of a gene in his lung cells, his children would be at greater risk than if it were caused by a base pair substitution. If the smoke had caused multiple different mutations in his lung cells, it would be more likely that one or more of the mutations would be passed to his children.
If he inherited a mutation that made him more susceptible to lung cancer, it may have been present in some of the gametes he produced and passed to his children is the circumstance that might his concern for his children be justified.
What do you mean by Mutation?A Mutation may be defined as sudden, stable, and inheritable changes in the genetic material of an organism.
Gametes of germline cells play an important role in the inheritance of mutation from parents to their offspring, which means that if a mutation has occurred in an egg or sperm cell, it will be more chances that the offspring carry mutated DNA.
Therefore, it is well-described above.

5. What can't the developing fetus be tested for?
Answer:
The two main types of prenatal testing are: Screening tests. Prenatal screening tests can identify whether your baby is more or less likely to have certain birth defects, many of which are genetic disorders. These tests include blood tests, a specific type of ultrasound and prenatal cell-free DNA screening. But they can be tested,, CVS is a test where the doctor collects a tiny piece of the placenta, called chorionic villus, which is then tested to check for chromosomal or genetic disorders in the baby.

Where do the tRNA take amino acids?
to the nucleus
outside of the cell
to the ribosome
Answer:
To The Ribosome.
Explanation:
To start, let's review. First off, tRNA means transfer RNA; type of RNA that carries amino acids to the ribosome. An amino acid is a carboxylic acid with an amino group and the building block of proteins. The nucleus is the "brain" of the cell, the control center of the cell, where genetic material (DNA) is found, the nucleus is in charge of everything that happens inside of a cell. The nucleus is the largest and most important part of the cell. Nuclear Envelope. The general purpose of the nucleus is to predetermine and control the production of proteins. It does this by storing the protein code in the DNA, which is hereditary. A cell is the smallest part of a living thing that can carry out the activities needed for life. The ribosome is a cell organelle constructed in the nucleolus and functioning as the site of protein synthesis in the cytoplasm; consists of rRNA and protein molecules, which make up two subunits. Since we're done reviewing, let's go through the processes of how the tRNA take the amino acids to the ribosome. There are two steps in protein synthesis. They are transcription and translation. During transcription, mRNA (Messenger RNA) is formed in the nucleus of the cell. After mRNA has been made, it leaves the nucleus and goes to the ribosomes in the cytoplasm, where translation occurs. (DNA never leaves the nucleus.) During translation, mRNA attaches itself to the ribosome. Then, tRNA (Transfer RNA) reads the mRNA codons (a codon is a sequence of three nucleotides that code for a protein) and attaches amino acids accordingly. This continues until tRNA reaches a stop codon. Translation is the second phase of protein synthesis. It follows transcription, in which the information in DNA is "rewritten" into mRNA. During translation, the mRNA attaches to a ribosome. Transfer RNA (tRNA) molecules then "read" the mRNA code and translate the message into a sequence of amino acids. Every three nucleotides in the mRNA make up one codon, which corresponds to one amino acid in the resulting protein. The ribosome tracks along the mRNA until it reaches a stop codon, signaling the assembly of mRNA and ribosome to break apart. Protein synthesis is the process where cells create proteins. There are two steps in protein synthesis. They are transcription and translation. During transcription, mRNA (Messenger RNA) is formed in the nucleus of the cell. After mRNA has been made, it leaves the nucleus and goes to the ribosomes in the cytoplasm, where translation occurs. (DNA never leaves the nucleus.) During translation, mRNA attaches itself to the ribosome. Then, tRNA (Transfer RNA) reads the mRNA codons (a codon is a sequence of three nucleotides that code for a protein) and attaches amino acids accordingly. This continues until tRNA reaches a stop codon.
Which of the following is an example of all countries of the world working together to protect the environment?
A: Clean air act
B: Montreal Protocol
C: RAD program
D: "Greenchill"
Answer:
C
Explanation:
An example of all countries of the world working together to protect the environment is the RAD program. The correct option is C.
What is the RAD program?RAD enables public housing organizations to reinvest in the supply of public housing by leveraging public and private finance and equity.
The Section 8 project-based voucher (PBV) and the Section 8 project-based rental assistance are the two HUD financing contracts that PHAs can use to operate a property under RAD (PBRA). PBV and PBRA contracts are longer-term, more reliable funding sources because they last 15 or 20 years.
Despite being listed as an asset, the RAD is not a financial asset, hence no income is seen as having been earned on this sum. The age pension asset test does not apply to any money received as a RAD, which may have an effect on recipients' age benefits.
Therefore, the correct option is C: RAD program.

what are three major lines of evidence that mitochondria arose from endosymbiosis with proteobacteria?
Answer:Most important are the many striking similarities between prokaryotes (like bacteria) and mitochondria: Membranes — Mitochondria have their own cell membranes, just like a prokaryotic cell does. DNA — Each mitochondrion has its own circular DNA genome, like a bacteria’s genome, but much smaller.
Explanation:
Most important are the many striking similarities between prokaryotes (like bacteria) and mitochondria: Membranes — Mitochondria have their own cell membranes, just like a prokaryotic cell does. DNA — Each mitochondrion has its own circular DNA genome, like a bacteria’s genome, but much smaller.
The DNA, plasma membrane, and reproductive process are the evidence that supports the endosymbiotic theory of mitochondria.
What is endosymbiosis?Endosymbiosis is a process that includes the engulfing of one cell by another. It is said that mitochondria originated endosymbiotically from proteobacteria.
The presence of the mitochondrial DNA although small shows similarity to bacterial DNA. The mitochondria are membrane-bound organelle like the prokaryotic bacteria.
The reproductive process of mitochondria resembles the bacterial reproduction method. The cytoplasm and the genetic material are divided in a similar fashion.
Therefore, DNA, reproduction, and membrane are evidence of the Endosymbiotic origin of mitochondria.

why textures in the same sill might vary, with finer grains along the margin and coarser grains toward the middle?
This question is related to the formation of sill through volcanic activity. See the explanation below.
What is responsible for the coarseness of sills?The reason for the variance in the coarseness of grains is the formation of igneous rocks happens deep in the earth and on this surface.
The texture of the sill is dependent on the rate at which it cools.
Coarse-grained sills are formed deep within the earth's crust while the other cool rapidly on the earth's surface.
