in the blank circle, draw the moon phases we would see if we were on Earth in the diagram and then write the name of that moon phase on the blank line

Answers

Answer:yThe Moon has phases because it orbits Earth, which causes the portion we see illuminated to change. The Moon takes 27.3 days to orbit Earth, but the lunar phase cycle (from new Moon to new Moon) is 29.5 days. ... As the Sun sets, the Moon rises with the side that faces Earth fully exposed to sunlight (5).

Carbonized fossils are made of:
O the carbon remains of the original organism
O carbon which replaced the plant or animal
O a cast of coal
O a mold left in coal

Answers

Carbonized remains are thin, approximately two-dimensional films of carbon preserved on a flat surface of rock. They are most often black in color, reflecting the fact that they composed mostly of carbon (as is coal, which is also black in color). Most fossils that exhibit “soft part” preservation are carbonizations.

I would say the answer is the Carbon remains of the original organism.

Answer: are the substance left after the organism was buried.

Explanation: I know this is not a answer but the carbon is rapidly buried until its rock.

The building blocks of DNA are like alphabet letters, because they:
A. Are each associated with a particular sound
B. Can be used in a variety of languages
C. Each have an uppercase and a lowercase form
D. Spell out different instructions depending on their order

Answers

Answer: The answer is D.

Explanation: It makes the most sense and explains how both the aplhebet and DNA have simrialities.

The building blocks of DNA are like alphabet letters because they spell out different instructions depending on their order. Thus, the correct option for this question is D.

What are the building blocks of DNA?

The building blocks of DNA are known as nucleotides. These nucleotides are made up of three parts. They are as follows:

A phosphate group.A pentose sugar.Nitrogenous base.

These nucleotides are arranged by one another with the help of a linkage known as phosphodiester linkage. Nitrogenous base in nucleic acids like DNA includes Adenine, Thymine, Cytosine, and Guanine. In the DNA, they are represented as A, T, C, and G. Due to this, the building blocks of DNA are like alphabet letters.

Therefore, the building blocks of DNA are like alphabet letters because they spell out different instructions depending on their order. Thus, the correct option for this question is D.

In cystic fibrosis, an important protein destined for the plasma membrane never makes it beyond the Golgi complex. This protein is necessary for Na and Cl- transport and is critical for maintaining mucous secretions of the appropriate consistency. Devise an explanation for why this may occur.

Answers

Answer:

The correct answer is - Golgi apparatus marks or tags on this protein as incorrect or dysfunctional tags which then prevents it from transported to the membrane.

Explanation:

The role of the Golgi apparatus is to process and package the proteins produced and come from ER and transfer them to the plasma membrane in order to transfer them to their target sites.

The Golgi apparatus marks or tags the proteins that are incorrect or dysfunctional, in order to prevent these proteins from transporting to the plasma membrane and harm the membrane. In CF, the case is similar as the Golgi apparatus tags these proteins as incorrect or dysfunctional.

In many parts of the world, there is a rock layer rich in the metal iridium. Iridium is very rare on Earth, but it is relatively common in meteorites and other debris that comes from outer space. All occurrences of this iridium layer are from the same geologic epoch, at the very end of the Cretaceous. Most of the fossils in rock layers below the iridium layer, including dinosaur fossils, do not appear in layers above the iridium layer.

Based on this evidence from the rock and fossil record,
A.
meteoroids and other space debris did not impact the Earth at the end of the Cretaceous.
B.
an asteroid impact likely caused a mass extinction at the end of the Cretaceous.

Why does a pea plant with the genotype Rr have round seeds, not wrinkled ones.

Answers

Answer:

Wrinkled peas need to have genotype rr, since the wrinkled trait (r) is recessive

R is the dominant allele ( codes for round seeds). The dominant allele will be “dominant” or expressed over the recessive allele which is r or wrinkled. So with Rr the dominant allele/ trait masks the recessive trait

Answer:

a. True

Explanation:

Bruce Wallace was a professor emeritus of genetics who performed many population studies. He worked in 1958 at the University of Cornell as a professor of genetics. In 1963, he performed a population study wherein the recessive allele It was at a frequency of 0.5. The population was propagated for 10 generations and the frequency of It for each generation was determined.

The result of this study showed that lt/lt died without reproducing, whereas, individuals with genotype +/+ were normal.

What is Bacteria?

Eukarya is not the correct answer because they have organelles and a nucleus. Archaea is not the correct answer because they have organelles and a nucleus.

Microbes known as bacteria have simpler cell structures than many other types of creatures. One DNA loop serves as their command center and houses all of their genetic data. Instead of a nucleus, some bacteria have an additional ring of genetic material called a plasmid.

Genes that offer the bacterium a competitive edge over other bacteria are frequently found in the plasmid. For instance, it might have a gene making the bacterium immune to a specific antibiotic.

Therefore, Bacteria is the correct answer because it lacks organelles or a nucleus. Protista is not the correct answer because they have organelles and a nucleus.

What is poisonous enough to kill 100,000 turkeys? That’s the question asked by scientists who studied a mass die-off of turkeys in Great Britain. It turned out that all the turkeys had eaten peanuts from Brazil. A fungus was growing on the peanuts. The fungus produced a dangerous poison called aflatoxin. Aflatoxins cause stomach pain, lung failure, cancer, and death in people and animals.

Farmers make a great effort to prevent fungi from growing on their stored crops. In a pile of grain or nuts, fungi have plenty of food and living space. The best way for farmers to prevent fungi from growing is to make sure there is not enough for fungi to survive and grow.
