The two ways in which bacteria are similar to birds are 2. They both have cell walls surrounding their cells and 4.They both use DNA as their genetic material.

1-They both have cell walls surrounding their cells: Both bacteria and birds have cell walls that provide structural support and protection. In bacteria, the cell wall is composed of peptidoglycan, while in birds, it is made up of various proteins and other components. The cell wall helps maintain the shape and integrity of the cells in both bacteria and birds.

2-They both use DNA as their genetic material: Both bacteria and birds use DNA (deoxyribonucleic acid) as their genetic material. DNA carries the genetic instructions necessary for the development, functioning, and reproduction of living organisms. In both bacteria and birds, DNA serves as the blueprint for the production of proteins and the transmission of hereditary traits to the offspring.

It is important to note that the other options mentioned in the question are not accurate similarities between bacteria and birds. Bacteria do not have a membrane-bound nucleus, and their offspring are not always genetically identical to themselves.

Genes store the information for making proteins and other gene products. The correct answer is D.

Genes are segments of DNA that contain the instructions for building and maintaining an organism. They store the genetic information that determines the traits and characteristics of an organism.

The information within genes is primarily responsible for the synthesis of proteins and other gene products. Proteins are essential molecules that perform a wide range of functions in the body, including structural support, enzymatic activity, signaling, and regulation of gene expression.

Genes encode the specific sequence of amino acids that make up a protein, and this sequence determines the protein's structure and function.

While genes do not store information solely for making carbohydrates, lipids, or DNA, they play a central role in the production of proteins and contribute to the overall complexity and functionality of an organism. Therefore, the correct is D.

Answer:

Due to change in genetic combination.

Explanation:

The results change as the number of trials increased because variation occur in the genetic combinations of chickens. It is important to breed the chickens repeatedly in this experiment in order to gain accuracy and attain best results. If the chicken is breed repeatedly, at the beginning changes occur in their offspring due to change in their genetic makeup so for accurate results repetition is necessary.

Water drains into the sinkhole pollution due to factories

The lake was created as limestone gradually dissolved, causing the sediment layer above it to collapse and creating the lake basin. Low lake levels and slow draining can be caused by bottom leaks, sinkholes, and swallets, long-term dryness, and a lack of recent, strong rainfall events.

Before the lake dried up, those walking along the shore of the sinkhole at Lake Jackson on Thursday would have been in three to four feet of water.

Answer:

B) When turtle eggs are found, move them to a safe place.

Explanation:

Based on the given article, we can learn that human encroachment has decreased the private lands/ spaces for animals to reproduce properly. One such case is that of the sea turtles. As the females only "deposit eggs on the land where they were hatched", it is important to keep them safe and undisturbed.

Therefore, one step that isn't helping the turtles is to move the eggs to a safe place. This is because female sea turtles "will never lay eggs" if their eggs are ever taken away from the original place they were laid at.

Thus, the correct answer is option B.

Answer:

A.

Explanation:

Choice A states, "Human liver cells make proteins that promote homeostasis, and neurons do not." This statement supports that complex, multicellular organisms are composed of specialized cell types with different functions. First, humans are multicellular organisms. Next, Choice A points out the difference between liver and neuron cell function (liver cells can promote homeostasis while neurons do not), which means that the cells that compose a human are specialized with different functions.

Vasoconstriction; their extremities will turn pale or blue as blood moves to the core of the body also their Sweating; the water released from their skin will evaporate.​

Vasoconstriction slows down the body's heat loss through the skin's blood vessels, warming the body. The body attempts to regain homeostasis as part of a negative feedback loop, which includes this action (maintaining a constant internal environment).

As an illustration, vasoconstriction causes the blood vessels to constrict and blood to move at a higher pressure in an effort to actively prevent a hypoxic reaction.

Your sweat glands produce perspiration when your hypothalamus feels that you are too hot, which helps to cool you off. The hypothalamus sends messages to your muscles to twitch in order to warm you up when it detects that you are too cold. Maintaining equilibrium is what we mean by this.

North Americans should consult their doctor or dietitian to determine if they need additional vitamin A in their diet. Vitamin A is found in many foods, including, sweet potatoes, carrots, spinach, and pumpkin. North Americans can consume a healthy diet that includes these foods to meet their vitamin A requirements.

Additionally, pregnant women should be cautious about taking excessive amounts of vitamin A because it can cause birth defects if taken during pregnancy. Liver toxicity can also result from intakes of vitamin A as little as 3 times the Daily Value.

There is only 1 different allele combination found in the genotype rryy, which is "rryy."

To determine how many different allele combinations would be found in rryy, we need to consider the given genotype.

The genotype rryy has two alleles for each gene: 'r' and 'y'. Since there are two different genes, we can find the total number of allele combinations using the multiplication principle.

Step 1: Determine the number of combinations for the 'r' gene. Since there is only one allele, there is only 1 combination (rr).

Step 2: Determine the number of combinations for the 'y' gene. Similarly, there is only 1 combination (yy).

Step 3: Multiply the combinations for each gene together (1 * 1).

Therefore, there is only 1 different allele combination found in the genotype rryy, which is "rryy."

20 molecules of ATP

Explanation:

Krebs cycle or also known as Tricarboxylic acid cycle (TCA) is the second stage of aerobic cellular respiration which occurs in the mitochondria. In the kreb cycle, pyruvate, which was synthesized in the first stage of cellular respiration (glycolysis) is broken down into carbon dioxide (CO2).

However, in the krebs cycle, two (2) ATP molecules is produced per glucose molecule that enters cellular respiration. Hence, according to this question, If 10 glucose molecules enter the Krebs cycle, (2 × 10) = 20ATP molecules will be possibly produced.

Madam Annie gave a birth to a pair of twins, a male and a female.  Both the baby boy and girl baby inherited the parent's genes. This is because of the inheritance that is being passed on to children via the heredity.

Meiosis is present in the gametes formation where the chromosomes set will be halved.

In the case of offspring it is the mix of both the mother and the genes of the father where they both need to express themselves in order to determine the genotype and the phenotype of an individual. Genetic recombination takes place in the case of progeny especially in the sexual reproduction.

In the case of sexual reproduction, it is one set coming out from one parent and one from another set and they express together making a child hybrid definitely the frequency of expression can be changing but the child is having traits of both.

Each gamete is genetically distinct because the DNA of the parent cell is shuffled before the cell divides. Gametes have half as many chromosomes as the other cells in the organism.

DNA is transmitted from one cell generation to the next by cell division, and ultimately from the parent organisms to their progeny. Prokaryotes and eukaryotes both divide their cells, but they do it in very different ways. Eukaryotic cells divide specifically through the processes of mitosis and meiosis. All eukaryotes undergo the process of mitosis, in which a parent cell divides into two daughter cells, each of which has the same number of chromosomes as the parent cell. Contrarily, meiosis only takes place in eukaryotic creatures that reproduce sexually. The cells required for sexual reproduction divide during meiosis to create new cells called gametes.
