Comparison Deer and chimpanzee Deer and rabbit Deer and kangaroo Deer and anteater anteater kangaroo Total Nucleotides Compared O deer 300 300 300 300 Number of Identical Nucleotides 297 295 Based on this analysis, which animal is the closest relative of the deer? O chimpanzee 278 290
Answers
Based on the provided analysis, the animal that appears to be the closest relative of the deer is the chimpanzee.
This conclusion is drawn by comparing the number of identical nucleotides between the deer and each of the other species: chimpanzee, rabbit, kangaroo, and anteater. In this analysis, a piece of DNA from a gene found in the deer is compared to the same gene in the four other species. The total number of nucleotides compared between the deer and each species is 300.
The number of identical nucleotides represents the level of similarity or shared genetic sequence between the deer and the other species. Based on the analysis, the deer shares 297 identical nucleotides with the chimpanzee, 295 with the rabbit, 278 with the kangaroo, and 290 with the anteater.
Among these comparisons, the highest number of identical nucleotides is observed between the deer and the chimpanzee, which is 297. This indicates a greater degree of genetic similarity between the deer and the chimpanzee compared to the other species. Therefore, the chimpanzee is considered to be the closest relative of the deer based on this analysis.

The addition of hydrogen peroxide in the cell breaks down the enzymes and causes cell death. The fact that hydrogen peroxide (H2O2) is stable in abiotic environments at room temperature and has a neutral pH makes it stand out from other general toxins. However, it kills cells quickly by producing highly reactive hydroxyl radicals.

Why is NAD+ so important if the cell takes the anaerobic pathway, so glycolysis to fermentation? Does the atp made in glycolysis depend on the NAD+ conversion to NADH in the first step? I am confused on why NAD+ is so important to atp production
Answers
Answer:
NAD+ (nicotinamide adenine dinucleotide) is indeed crucial for ATP production, even in anaerobic pathways such as glycolysis followed by fermentation. Allow me to explain the significance of NAD+ and its role in ATP production.
During glycolysis, glucose is broken down into pyruvate, producing a small amount of ATP and NADH. The conversion of NAD+ to NADH occurs during the oxidation of certain molecules, including glucose, in the pathway. This conversion is essential because NADH carries high-energy electrons that can be used in subsequent steps to generate more ATP.
In aerobic respiration, NADH is further utilized in the electron transport chain (ETC) within the mitochondria. The ETC transfers electrons from NADH to oxygen, generating a significant amount of ATP through oxidative phosphorylation. However, in anaerobic conditions where oxygen is limited, like during fermentation, the ETC cannot function.
Here's where NAD+ becomes critical. In order to keep glycolysis running and continue generating ATP, the NADH produced during glycolysis must be converted back to NAD+. This allows glycolysis to continue producing ATP, even without the presence of oxygen. Without a mechanism to regenerate NAD+, glycolysis would halt due to a lack of NAD+, leading to a severe reduction in ATP production.
Fermentation pathways differ depending on the organism, but they all involve the regeneration of NAD+. For example, in lactic acid fermentation, pyruvate is converted into lactate, which involves the transfer of electrons from NADH to pyruvate, regenerating NAD+. Similarly, in alcoholic fermentation, pyruvate is converted into ethanol, again regenerating NAD+.
In summary, NAD+ is essential in anaerobic ATP production because it serves as a coenzyme that accepts electrons and facilitates the conversion of NADH back to NAD+. By regenerating NAD+, cells can sustain glycolysis and continue producing ATP, even in the absence of oxygen.

Population growth rate for Zambia is 0.8 % when CBR= 2.9%, Immigration = 1%,CDR = 2.1%, Emigration = 1% are as given above.
What is CBR?The crude birth rate is the number of live births per 1,000 of the population at the midyear census. long explanation The crude birth rate is the number of live births per 1,000 of the expected population at the midyear mark.
Given data;
CBR= 2.9%, Immigration = 1%,
CDR = 2.1%, Emigration = 1%
Now to find the Population Growth Rate use the given formula;
(CBR + Immigration) - (CDR + Emigration) = Population Growth Rate
Population Growth Rate= (CBR + Immigration) - (CDR + Emigration)
the current population of Zambia =18.92 million
now
CBR= 2.9% of 18.92 million=548680
CDR = 2.1% of 18.92 million=397320
Immigration = 1% of 18.92 million=189200
Emigration = 1% of 18.92 million=189200
now putting the values on eq.
Population Growth Rate= (CBR + Immigration) - (CDR + Emigration)
Population Growth Rate= (548680 +189200)-(397320 + 189200 )
Population Growth Rate=151360 *100/18.92 million

Seeds are reproductive or not ?
Answers
Answer: Yes
Explanation: Monocots produce one cotyledon, while dicots produce two. Because seeds are reproductive structures and thus important to a species' survival, plants have evolved many mechanisms to ensure their survival. One such mechanism is seed dormancy. Dormancy comes in two forms: seed coat dormancy and embryo dormancy
Answer:Plants that reproduce by seeds. Seed plants have special structures on them where male and female cells join together through a process called fertilisation. After fertilisation, a tiny plant called an embryo is formed inside a seed.
1. How do you think the karyotype of cancerous cells might appear different
from the karyotype of a non-cancerous cell?
2. What are cyclins and cyclin-dependent kinases? What do these proteins do in
a cell?
Answers
Answer:
The cancer cells depict major changes in terms of their chromosomal structure, gene composition, and chromosome number. Therefore, while comparing the karyotype of a healthy person and a person with cancer, the changes in terms of mis-segregation, aneuploidy, anaphase lagging, and others can be observed. This can be attributed to the increased rate of cell division which is not under strict control of the cell cycle checkpoints. This bypass of cell cycle check results in increased abnormalities like improper segregation, increase or decrease in several chromosomes after cell division, and failure in detachment of chromosomes during meiosis. These changes are then manifested in the form of cancer as these cells continuously replicate and produce many copies over time and take over the healthy cells.

Body (or somatic) cells in humans are diploid, meaning they have two sets of chromosomes (one from each parent).
The process of mitosis, which divides the duplicated genetic material held in a parent cell's nucleus into two identical daughter cells, begins with the prophase. The chromatin, a combination of DNA and proteins found in the nucleus, condenses during prophase.

In E. coli bacteria, the lac operon contains genes that code for enzymes that break down lactose. Which statement describes when the genes in the lac operon are expressed?
Answers
The genes in the lac operon are expressed when lactose is present and the repressor protein is unable to bind to the operator region.
In E. coli bacteria, the lac operon contains genes that code for enzymes involved in lactose metabolism. The lac operon is a regulatory system that controls the expression of these genes. The expression of the genes in the lac operon is tightly regulated and depends on the presence or absence of lactose and glucose in the environment.When lactose is present, it binds to the repressor protein (lac repressor), causing a conformational change in the repressor. This change prevents the repressor from binding to the operator region of the operon. As a result, RNA polymerase can bind to the promoter region and transcribe the genes, leading to the production of the enzymes that break down lactose.In the absence of lactose, the repressor protein binds to the operator region and blocks RNA polymerase from initiating transcription. This prevents the expression of the genes in the lac operon.For more questions on protein
