What is the correct order of processes in the accretion of planetesimals?
1)Masses of matter form around dust grain, masses of matter collide, and atoms and molecules are added to dust grain.
2)Masses of matter collide, masses of matter form around dust grain, and atoms and molecules are added to dust grain.
3)Atoms and molecules are added to dust grain, masses of matter form around dust grain, and masses of matter collide.
4)Masses of matter collide, atoms and molecules are added to dust grain, and masses of matter form around dust grain.

Answers

Answer 1

Answer:

The correct option is 3. Atoms and molecules are added to dust grain, masses of matter form around dust grain, and masses of matter collide.  

Explanation:

Two theories explain how planets get formed. One of them is The gravitational instability, and the other one is the Planetesimal Hypothesis.

The planetesimal hypothesis says that a planet formation is a process in which dust particles and gas collide and get stick together in a process known as coagulation. This makes place to grains production. These grains enhance their sizes up to a point in which they form bodies big enough to be called planetesimals. When planetesimals are formed, they start a gravitative interaction with other planetesimals of different sizes, and by collision, they form bigger planetesimals that accrete the smaller ones and end up forming a proto-planet. Planets and giant planets get formed by accretion of solid planetesimals. The term accretion refers to the solids agglomeration to form bigger objects, such as planets.

Answers

Answer:

The spinal cord is a long, thin, tubular structure.

Explanation:

The spinal cord is a long, thin, tubular structure made up of nervous tissue, which extends from the medulla oblongata in the brainstem to the lumbar region of the vertebral column. It encloses the central canal of the spinal cord, which contains cerebrospinal fluid.

Answer:

it is a tissue

Explanation:

The next morning your team returns to work in the laboratory, where you get a call from the sheriff. The family of the three missing boys is pressuring him for information. Your team begins the final osteological exam. After careful examination, you produce your final inventory. You are working with the same number of bones, but you now have determined which side of the body they come from (when applicable).
You have:_______.
• 3 skulls
• 6 femora (4 right and 2 left)
• 4 os coxae (All adolescent males, 1 right and 3 left)
• 2 humeri (both right)
• 2 tibiae (both left)
• 5 scapulae (3 right and 2 left)
1. Based on the revised inventory, would you change your MNI? If so, what would be the new MNI?
2. What do you tell the sheriff? Are these the missing boys?

Answers

Answer:

See below

Explanation:

1. Yes, the MNI ought to be changed in light of the revised inventory. Since 4 of the 6 femora are right sided, they would belong to different individuals, so the MNI would now be stated as 4.

2. The sheriff would be told that the possibility of suspecting 22 individuals is very narrow, though not impossible. It is also unlikely that the victims are numbered less than 4 in accordance to the bones found.

Macromolecules in the cell can often interact transiently as a result of noncovalent interactions. These weak interactions also produce stable, highly specific interactions between molecules. Which of the factors below is the most significant in determining whether the interaction will be transient or stable?
a) the size of each molecule
b) the number of chemical bonds between the molecules
c) the concentration of each molecule
d) rate of synthesis

Answers

Answer:

The correct answer is option b) "the number of chemical bonds between the molecules".

Explanation:

Chemical bonds are the forces that enable the formation of compounds. The number of chemical bonds is a determining factor to know if an interaction will be transient of stable. The more chemical bonds the more stable an interaction will be. Few chemical bonds between molecules makes an interaction unstable and easy to break, enabling transient interactions that are key to certain biological pathways.

The Consumer Product Safety Commission (CPSC) is a U.S. government agency that is responsible for protecting consumers from unsafe products that are in Option C. The CPSC has the authority to take various actions to help protect consumers.

What is the Consumer Product Safety Commission?

The CPSC has the authority to recall any consumer product that poses a substantial risk of injury or death to consumers. The CPSC can require companies to recall their products, issue warnings to consumers, and take other appropriate actions to protect the public. Forcing a store to issue store credit is not a typical action that the CPSC would take to protect consumers. While the CPSC can investigate complaints and take legal action against companies that violate safety standards, it does not have the authority to force stores to issue store credit.

Hence, the Consumer Product Safety Commission (CPSC) is a U.S. government agency that is responsible for protecting consumers from unsafe products that are listed in Option C.

B. Eukaryotes do Tnx in the nucleus and Tnl in the cytoplasm.
C. Tnx and Tnl occur together in the cytoplasm of Prokaryotes and Eukaryotes.
D. Tnx and Tnl both occur in the nucleus in eukaryotes and prokaryotes.

Answers

Answer:

A and B

Explanation:

The correct statements about transcription and translation would be that prokaryotes conduct transcription and translation together in the same cellular compartment and eukaryotes do transcription in the nucleus and translation in the cytoplasm.

Prokaryotes generally lack a nucleus and other membrane-bound organelles and as such, their genetic materials lie freely within the cytoplasm. Hence, transcription and translation take place within the same cellular compartment, which is the cytoplasm.

Eukaryotes, however, have a nucleus and other membrane-bound organelles such as mitochondrion. Their genetic materials lie majorly in the nucleus. Hence, transcription takes place within the nucleus. Thereafter, the transcribed mRNA is transported to the cytoplasm where they get attached to ribosome and tRNA and translated into proteins.

The correct options are A and B.

Answer:

The theory of evolution by natural selection

Explanation:

Nowadays, it is widely accepted that chimpanzees are primates closest related to us. Darwin's postulated "The theory of evolution by natural selection", in the book "On the Origin of Species" in 1859. It is a theory that explains how species evolve over successive generations by gradual changes and the selection of the most adaptive phenotypes. Anatomical, fossil, and genetic evidence support the idea of an evolutionary link as Darwin predicted between hominids (humans) and other primates.

In regard to genetic evidence, whole-genome sequence analyses have shown that humans and chimpanzees share about 98% of sequence homology. Moreover, according to the phylogenetic tree, both species evolved from one common ancestor that was present approximately 4 million years ago.  

In regard to anatomical and fossil evidence, it has been discovered that the chimp brain has a similar size to human extinct relatives, and thereby also supporting an evolutionary link between both species.

The speckled chicken on the right results from a cross between a black and white chicken. Explain what type of inheritance this would be, and draw a punnett square to show how this would happen.

Answers

Answer:

- Codominance

- 100% speckled chicken

Explanation:

This gene inheritance is called codominance, where both alleles can be expressed. In these cases, heterozygote individuals instead of showing an intermediate phenotype, express both alleles. Their phenotype is an additive expression of their parents' genes.

When two individuals, homozygous for a certain trait, are crossed they produce heterozygous individuals that express both alleles equally.

A typical example of codominance is the case of speckled chicken, the product of the cross of a black individual with a white individual. Black chickens (BB) only have this gene for feather color, while white chickens (WW) only have the gene for white feathers. When they cross, their progeny will have both genes (BW), and both of them will be expressed as speckled feathers.

7. growth in thickness

10. lateral meristem

11. vascular cambium

Both:

8. occurs in plants that live many years

Explanation:

Plant primary growth starts with successive cell division cycles in undifferentiated cells that form the shoot apical meristem, thereby lengthening roots and stems. The meristems represent a type of tissue involved both in primary and secondary growth. Herbaceous plants have only primary growth and grow in length.  

Secondary growth is caused by the growth of the vascular cambium (cambia) and lateral meristems. It is characterized by an increase in thickness of stems and roots. Vascular plants (i.e., plants with a xylem and phloem system) have secondary growth.

In woody plants, the primary and the secondary growth patterns occur across years, and thus they can increase their length (primary tissue growth) and diameter (secondary tissue growth).
