Answers
Prokaryote reproduction is similar to mitosis in that it involves the replication and division of the genetic material, followed by cell division.
Explaining Procaryotes, and answers to other parts of the questionProkaryote reproduction is similar to mitosis in that it involves the replication and division of the genetic material, followed by cell division. However, prokaryotes do not have a nucleus, so the process is simpler and does not involve the formation of a mitotic spindle or the separation of chromosomes into daughter nuclei.
Thermophilic prokaryotes are most likely archaea, as they are known to thrive in extreme environments such as hot springs and deep-sea vents, whereas bacteria are more commonly found in moderate environments.
Algae have two features that make them like plant cells: they contain chloroplasts for photosynthesis and have a cell wall made of cellulose.
Scientists had problems deciding if euglenoids were more similar to plants or animals because they possess characteristics of both groups. Like plants, they have chloroplasts and can perform photosynthesis, but like animals, they can move using a flagellum and can consume other organisms for nutrients. This led to some debate about how to classify them, but they are now generally considered to be a type of protist.

A scientist is attempting to provide support for the hypothesis that RNA was the first genetic material. Which of the following would be a workable alternate hypothesis?
(A) RNA, like DNA, is a carrier of genetic information and contains the nitrogen bases adenine, guanine, and cytosine.
(B) RNA can be observed to self-replicate without the assistance of proteins, while DNA always requires protein-based enzymes to replicate.
(C) RNA exists in both single-stranded and double-stranded configurations; however, it is less stable compared with DNA.
(D) Transfer RNA and ribosomal RNA are products of transcription, but they are not translated as is mRNA.
Answers
If a scientist is attempting to provide support for the hypothesis that RNA was the first genetic material, then RNA can be observed to self-replicate without the assistance of proteins, while DNA always requires protein-based enzymes to replicate would be a workable alternate hypothesis (Option B).
What are the functions of RNA?The functions of RNA are not limited to transporting the genetic material from DNA to protein but also act as catalytic agents in some situations, which are called ribozymes, in addition to the reservoir of genetic information for viruses.
Therefore, with this data, we can see that the functions of RNA are not limited to transport genetic information.

The fossil of an organism with a sprawling gait and middle ear bones, found in a 250-million-year-old rock layer.
historically, non-mammalian synapsids were believed to have advanced from reptiles, and consequently defined as mammal-like reptiles in classical systematics, and primitive synapsids were also known as pelycosaurs, or pelycosaur-grade synapsids.
Mammals belong to a larger institution of animals referred to as synapsids. these are vertebrate animals that produce amniotic eggs and have a single hole, or temportal fenestra, in the back of their eye socket. The sister organization to the synapsids are the sauropsids, all cutting-edge 'reptiles' (which includes birds) and their fossil family.

The fossil that provided the strongest evidence for the discovery of a transitional species between early non-mammalian synapsids and mammals is: the fossil of an organism having a sprawling gait and middle ear bones, that was found in a rock layer that was 250-million-year-old.
Synapsids were the earliest known reptiles that were present during the Carboniferous period. The term synapsid refers to the fused arch. They evolved from the basal amniotes along with the Sauropsids.
Gait refers to the way of movement of any animal. Various animals have different types of gait or locomotion. These can be crawling, flying, walking, creeping, slithering or swimming.

Which of the following represents an in vivo method for cultivating viruses.
a.) HeLa cells
b.) Pure bacterial cell cultures
c.) Embryonated chicken eggs
d.) Lung cell culture
Answers
Embryonated chicken eggs represents an in vivo method for cultivating viruses. (option c)
To cultivate viruses in a living system, an in vivo method is used. Among the options provided, embryonated chicken eggs are the most commonly used method for culturing viruses in a living organism.
HeLa cells: HeLa cells (a) are human cancer cells commonly used in laboratory research, but they are not a living organism suitable for virus cultivation.
Pure bacterial cell cultures: Bacterial cell cultures (b) are often used to study bacteriophages, which are viruses that infect bacteria. However, this method involves culturing viruses in bacterial hosts and does not involve a living organism.
Embryonated chicken eggs: Embryonated chicken eggs (c) are a widely used method for virus cultivation. In this method, viruses are injected into the developing embryo, which provides an environment for viral replication. The embryos provide a controlled and nutrient-rich environment for the viruses to grow and propagate.
Lung cell culture: Lung cell culture (d) involves growing lung cells in a laboratory setting. While this method can be used to study certain viruses, it is an in vitro (outside a living organism) method rather than an in vivo method.
In conclusion, the in vivo method for cultivating viruses among the options provided is embryonated chicken eggs. This method provides a living system in which viruses can replicate and propagate. (option c)

Answers
Increased levels of salicylic acid in vascular tissue fluid suggest it's important for systemic signaling and defense against TMV.
The observation that levels of salicylic acid increase in the vascular tissue fluid of a plant when a single leaf is infected with TMV suggests that salicylic acid is important for systemic signaling in response to TMV infection, activating the plant's defense response.
Systemic acquired resistance (SAR) is a defense mechanism in plants that provides protection against future pathogen attacks. Salicylic acid is proposed to be an important hormone for the activation of SAR in response to infection by tobacco mosaic virus (TMV). The observation that levels of salicylic acid increase in the vascular tissue fluid of a plant when a single leaf is infected with TMV suggests that salicylic acid is involved in the systemic signaling process that activates the plant's defense response. This allows the plant to mobilize a rapid and effective defense response against future pathogen attacks.

As a result of this mutation the individual’s blood cells take on a sickle shape under certain conditions Which type of mutation causes sickle cell anemia
Answers
Answer:
POINT MUTATION (SUBSTITUTION)
Explanation:
A point mutation is that mutation which involves only one nucleotide base. Point mutation can, however, occur in different ways such as SUBSTITUTION. Substitution point mutation is that which involves the replacement of a single nucleotide base by another in a gene sequence.
This is the case in this question regarding the mutation that causes sickle cell anaemia. According to this question, Sickle cell anemia is a disease that occurs when a mutation in the base pair of the hemoglobin beta gene causes a SINGLE replacement of GLUTAMIC ACID (Glu) by VALINE (Val). This shows that it is a type of SUBSTITUTION POINT MUTATION.

(2 marks)
Answers
Answer:
Explanation:
To solve this problem, let's represent the heterozygous yellow-seeded plant as "Yy" and the homozygous yellow-seeded plant as "YY."
i. When crossing a heterozygous yellow-seeded plant (Yy) with a homozygous yellow-seeded plant (YY), we can set up a Punnett square to determine the possible offspring genotypes:
Y Y
y Yy Yy
y YY YY
ii. The genotypic ratio is 2:2 or 1:1 for the possible offspring genotypes: Yy and YY.
The phenotypic ratio is also 2:2 or 1:1 for the possible offspring phenotypes: yellow-seeded (YY and Yy).
Question 2:
To determine the probability of specific outcomes, we need additional information about the parental genotypes and their inheritance patterns. Please provide the genotypes of the true breeder from F1 and the non-true breeding yellow-seeded plant for a more accurate calculation.
