Question 3 A girl inherited the dominant trait of dimples but her sister did not because both parents had different Select one: chromosomes for dimples. alleles for dimples. genes for dimples. genotypes for dimples.
Based on the fact that the girl inherited the dominant trait of dimples but her sister did not, it means both parents had different genotypes for dimples.
What is a dominant trait?A dominant trait is a trait that always appear on every generation.
When the alleles for a trait are the same, the genotype is said to be h0m0zygous.
If the alleles for a trait are different, the genotype of the offspring is said to heterozygous.
Since the girl inherited the dominant trait of dimples but her sister did not, it means both parents had different genotypes for dimples.

Which of the following lists represents cell structures that are found in both animal and plant cells?
A - Cell membrane, Golgi apparatus, Nucleolus
B - Large vacuole, Cell Wall, Chloroplast
C - Mitochondria, Flagella, Cilia
D - Lysosomes, Ribosomes, Chloroplast
Answer: b
Explanation:
The group that represents cell structures that are found in both animal and plant cells is Cell membrane, Golgi apparatus, Nucleolus. The correct option is A.
What is cell?Cells are the fundamental cornerstones of all life. Vast amounts of cells make up the human body.
They support the body's structure, absorb nutrients from food, convert those nutrients into energy, and perform specialized functions.
A cell is made up of three parts: the cell membrane, the nucleus, and the cytoplasm that lies between the two.
The cytoplasm contains intricate arrangements of fine fibers as well as hundreds or even thousands of tiny but distinct structures known as organelles.
All living things, from microorganisms to humans, rely on cells for structure and function. Scientists regard them as the tiniest form of life.
Cell membrane, Golgi apparatus, and Nucleolus are the cell structures found in both animal and plant cells.
Thus, the correct option is A.

They also have small bodies, and blue and black spots to hold there poison. They are one of the most reconizeable amphibians.
Explanation:
What do you think would happen to the rates of photosynthesis of seagrass and algae if their habitat became muddied when channel clearing caused sediment to stay mixed in with the water?
Answer:
They would lose their green color
Explanation:
The light doesn't reach them because the mud is blocking it, so they can't preform photosynthesis.

A decrease in global distribution of temperate grasslands is likely a result of
A) rainfall between 500 and 900 mm per year
B) decreased rainfall below 900 mm per year
C) warmer than average global temperatures
D) cooler than average global temperatures
Answer:
D) cooler than average global temperatures.
Explanation:
A decrease in global distribution of temperate grasslands as a result of cooler temperature which is required by the temperate grasslands. these grasslands requires about 25-30 inches rainfall per year and the temperature ranges from 0 Fahrenheit in winter to 90 Fahrenheit in summer. The average temperature of the earth is 58 Fahrenheit so the temperature of the temperate grasslands goes lower than average global temperature which decrease its distribution.

What is RNA?Ribonucleic acid is a nucleic acid found in all living cells that resembles DNA in structure. RNA, unlike DNA, is typically single-stranded.
Instead of the deoxyribose found in DNA, the backbone of an RNA molecule is made of alternating phosphate groups and the sugar ribose.
In protein synthesis, three types of RNA are involved. They are ribosomal RNA, messenger RNA (mRNA), and transfer RNA (tRNA) (rRNA). Ribosomes are required for protein synthesis and are formed by rRNA.
Transfer ribonucleic acid (tRNA) is an RNA molecule that aids in the translation of a messenger RNA (mRNA) sequence into a protein.
tRNAs function at specific sites on the ribosome during translation, which is the process by which an mRNA molecule is converted into a protein.
Thus, the correct option is A.

What is diffusion and how does it work? What is osmosis and how does it work?
Answer:
Diffusion is the net movement of anything from a region of higher concentration to a region of lower concentration. Diffusion is driven by a gradient in concentration. The concept of diffusion is widely used in many fields, including physics, chemistry, biology, sociology, economics, and finance
Explanation:
Osmosis is the movement of water through a semipermeable membrane according to the concentration gradient of water across the membrane, which is inversely proportional to the concentration of solutes. ... The semipermeable membrane limits the diffusion of solutes in the water

Which two cell parts are most likely found in both types of cell? Ocell wall and cell membrane O lysosome and vacuole O vacuole and centriole O lysosome and chloroplast
Answer:
The correct answer is - lysosome and vacuole.
Explanation:
In the cells of animals and plants, there are many similarities and some differences as well. These similarities and differences include the organelle they both have common or specific to a particular cell.
Lysosome and the vacuoles are two organelles found in both cells; plants, and animals. In plants, there is a central vacuole large in size whereas in the animal cells the numbers are much higher and size is smaller in size. Lysosomes are also present in both animals as well as the plant cell.
Thus, the correct answer is - lysosomes and vacuole.

Consider these scenarios. Scenario A: Carmen reads an article in Tasty Food magazine stating that eating an apple can help you feel awake and alert. Scenario B: Yuki reads an article in the Professional Journal of Medicine stating that ginger root can help prevent some types of cancer. Which article is more likely to have been peer reviewed? How do you know?
Answer: The article read by Yuki is more likely to have been peer-reviewed because this article is part of a Journal Medicine and peer-review is mandatory in most Academic journals before publication.
Explanation:
Peer-review implies academic works such as research papers or articles are verified by peers of the author. For example, a medical article is evaluated by other experts in the same field with similar knowledge and competences. This process is essential to guarantee the information is accurate and reliable. Moreover, peer-review is used mainly in academic journals or academic papers. Indeed, most academic journals require new articles or papers to be peer-review before these are published in the journal.
In this context, it is likely the article red by Yuki has been peer-reviewed because this is part of a Medicine journal and it is a general standard for articles in journals to be reviewed. Also, this is not a requirement for articles published in regular magazines such as Tasty Food magazine.
