Answer:
A person can have normal chromosomes in number and structure, but still have a disease or condition caused by a mutation in one or more of the genes on the chromosomes. A single gene defect usually does not cause the chromosome structure or number to be abnormal.

TRUE OR FALSE?
The fossil record is incomplete and does not contain all of the Earth's past organisms. Why have some organisms been found as fossils while others have not?
A. Fossils only exist for organisms that lived over 3 million years ago.
B. Fossils only exist for organisms that had shells or hard outer body coverings.
C. Only very large organisms have enough body mass to result in fossil formation.
D. Most organisms die and decompose without leaving any fossil remains.
Answer:
The answer is D.
Explanation:
We can easily knock out answer choice A, as fossils only take around 10,000 years to form completely. Not just for the organisms that lived 3 million years ago. Answer B as well, since theres been fossils for about just every animal out there. Answer C, we have seen the tiniest of organisms turn into fossils before, so this is outright wrong. Answer D, is correct. Why? Because fossils need the PERFECT conditions to be properly made. We´ve all seen a dead cat on the road or two. Everytime we visit, we notice how slowly more and more deterioated the body gets. Until theres nothing but maybe the skull and some other few spare bones left. Which those bones, soon turn into fertilizer for the ground / dirt beneath it.

which two products are bromelain likely to produce when breaking down proteins
amino acids
fatty acid
monosaccharides
nucleic acid
polypeptides
disaccharides
The two specific products that bromelain produces when breaking down proteins are polypeptides and amino acids.
What are proteins?Proteins are a major group of biological macromolecules composed of a linear chain of aminoacids that are linked by means of peptide bonds.
Proteins are fundamental macromolecules present in all biological systems and they can be made by one or more polypeptides in order to form molecules that exhibit primary, secondary, tertiary, and quaternary structures.
These macromolecular structures can be evidenced by the tridimensional shapes that adopt different proteins, which can be globular or fibrous.
In conclusion, the two specific products that bromelain produces when breaking down proteins are polypeptides and amino acids.

how do 2 siblings from the same parents look different to each other
Answer:
After all, kids get their genes from the same parents. But brothers and sisters don't look exactly alike because everyone (including parents) actually has two copies of most of their genes. And these copies can be different. Parents pass one of their two copies of each of their genes to their kids.

In the box provided explain why living organisms
contain more hydrogen atoms than any other
atoms, yet 65% of a typical organism's mass is
oxygen
І
Answer:
Explanation:
Living organisms are mostly made of water. Water is a molecule made from 2 hydrogen atoms and 1 oxygen atom, H2O. Now even though there are 2 hydrogen atoms for every oxygen atom in a living organism oxygen atoms are much heavier than hydrogen atoms. Hydrogen atoms are more than 15 times lighter than oxygen atoms and this is why they can be fewer atoms of oxygen in the body but they will still represent a lot of its weight.
Answer:
The living species comprise more number of hydrogen atoms in comparison to any other atoms, still 65 percent of the usual organism's mass is oxygen. The prime reason for this is that an atom of oxygen comprises sixteen times more mass in comparison to a hydrogen atom.

Which researcher proposed that dreams are a chance for problem solving? A. Sigmund Freud B. Matthew Wilson C. Rosalind Cartwright D. J. Allan Hobson
Answer:
The answer is Rosalind Cartwright.
Explanation:
A researcher who proposed dreams which are a chance for problem-solving is Rosalind Cartwright. Thus, the correct option for this question is C.
What is Problem-solving?Problem-solving may be defined as an instance of illustrating a problem that significantly determines the consequences of the problem along with identification, prioritization, and selection of alternatives for a solution; and implementing a solution.
Rosalind Cartwright was a neuroscientist who proposed the theory of dreams with respect to the chance for problem-solving. She hypothesized the complete mechanisms of dreaming which is particularly based on REM sleep. It is a way to process emotions, experienced during the day.
Therefore, a researcher who proposed dreams which are a chance for problem-solving is Rosalind Cartwright. Thus, the correct option for this question is C.

Is cystic fibrosis autosomal or sex-linked?
Answer:
Crystic fibrosis is an autosomal recessive disorder/disease. It is the resultant of a mutated copy in a gene. Both copies must have a mutation present in the CFTR gene to have crystic fibrosis. If only one copy is mutated, they are carriers and do not have cf or crystic fibrosis themselves.

Answer: A
Explanation:
Describe the following types of cell signaling:
Autocrine:
Juxtacrine:
Endocrine:
Paracrine:
Answer:
Autocrine = Autocrine signaling is a form of cell signaling in which a cell secretes a hormone or chemical messenger (called the autocrine agent) that binds to autocrine receptors on that same cell, leading to changes in the cell.This can be contrasted with paracrine signaling, intracrine signaling, or classical endocrine signaling.
Juxtacrine = Juxtacrine signalling (or contact-dependent signalling) is a type of cell–cell or cell–extracellular matrix signalling in multicellular organisms that requires close contact.
Endocrine = Endocrine signaling occurs when endocrine cells release hormones that act on distant target cells in the body. Endocrine signaling can be distinguished from two other types of signaling: neural signaling and paracrine signaling. ... Neurons are connected to their target cells via synapses.
Paracrine = Paracrine signaling is a form of cell signaling or cell-to-cell communication in which a cell produces a signal to induce changes in nearby cells, altering the behaviour of those cells.
Which of the following statements correctly describe centrioles? Check all that apply.
A) Centrioles are only found in animal cells.
B) Spindle fibers are connected to centrioles.
C) Centrioles are only present during metaphase.
D) Chromosomes and centrioles are made of the same materia
Answer:
a,b
Explanation:
edge
The statements that correctly describe centrioles are that they are only found in animal cells and spindle fibers are connected to centrioles. Therefore, the correct option is A and B.
What are centrioles?Centrioles are cylindrical structures found in animal cells that play a role in cell division.
Statement A- Centrioles are only found in animal cells and not in plant cells or bacteria. Hence, it is correct.
Statement B—The spindle fibers are connected to centrioles and play a crucial role in pulling the chromosomes apart during cell division. Hence, it is also correct.
Statement C- Incorrect, as centrioles are present throughout the cell cycle, not just during the metaphase stage.
Statement D- Incorrect, as chromosomes and centrioles are not made of the same material. Chromosomes are composed of DNA, while centrioles are made of microtubules. Therefore, the correct option is A and B.
