plate 2 there were 38 green leaved plants and 11 white leaved plants? What is the parental genotypes (given white is recessive)?
Answer:
Aa and Aa (can be any other letter, but both need to be heterozygous)
Explanation:
1 out of 4 offspring from the cross are white, so to verify that the genotypes of the parents are correct we can do 1÷4×49 (number of plants) and that equals 12.25, which is close enough to 11. So the genotypes of the parents are Aa and Aa.
In simple staining with a basic dye, do the gram-positive and gram-negative bacteria differ in retaining color?
Answer:
The above shows the procedures of the Gram's staining method, The result and important of colour in differentiating the bacteria. A little insight into staining endospore.
Explanation:
Stainings is a reagent or dye used to stain microscope specimens so as to make some structures visible.
Peptidogycan is a derivative polymer of glycan and peptides found in bacterial cell walls and varies in compositional concentration from species to species.
Cell wall- A thick, fairly rigid, layer formed around individual cells of bacteria, Archaea, fungi, plants, and algae (but not animals and other protists which generally have cell membranes without cell walls). The cell wall is external to the cell membrane and serves a structural function helping the cell maintain its shape and protecting the cell from damage.
There different types of staining techniques and classification based on the aim of the experiment and here is a few;
The etymology is from Gram + positive, is named after Dan ish bacteriologist Hans Christian Gram, who invented the Gram staining technique.
Used in bacteriology , bacteria that stains dark blue or violet after Gram staining, due to large quantities of peptidoglycan in the cell wall are gram positive.
And gram-negative bacteria is one that is not stained violet by Gram's method.
A spore is thick resistant particle produced by a bacterium or protist to survive in harsh or unfavorable conditions.
Spore staining (malachite green) however can be used to differentiate sporulating bacteria species.

Answer:

There are two principal types of cells in the organism: Somatic diploid cells (2n) that reproduce by the process of mitosis, and germ cells that are diploid reproductive cells in charge of gamete production. Germ cells divide by mitosis and meiosis. Through the process of mitosis, they originate more sexual cells, but through the process of meiosis, they give place to haploid gametes, called sperm and egg cells, through the gametogenesis process.
Both somatic cells and germinal cells will end their cycle becoming two daughter cells with the same genetic dotation. Mitosis produces two daughter diploid cells (2n) from a diploid somatic cell (2n). During mitosis, the whole cell (23 chromosomes) first duplicates producing 46 chromosomes. Then the duplicated cell separates, producing two equal cells carrying 23 chromosomes each.
When we talk about the cell cycle, we refer to the interphase and the cell division (mitosis or meiosis).
The interphase occurs before mitosis and involves 90% of the cell cycle. The interphase is conformed of the G1, S, and G2 stages.
• During the G1 stage, it occurs a high intense biochemical activity. The cell duplicates its size, and the organelles and other molecules and cytoplasmatic structures also double. Some structures, such as microtubules and actin filaments, are synthesized from zero. The endoplasmic reticulum increases in size and produces a membrane for the Golgi complex and vacuoles, lysosomes, and vesicles. During this stage, the pair of centrioles separate, and each centriole duplicates. Mitochondria and chloroplasts also replicate.
• During the S stage, the DNI replication process occurs. This is the only stage in which the DNI molecule replicates. The synthesis of histones and other associated proteins also occurs.
• G2 stage is the interphase last step. DNI molecule begins to slowly condensate. The centrioles duplication process completes. The spindle fibers get assembled.
Once the whole interphase is completed, mitosis occurs involving 10% of the cell cycle.
During mitosis, the original cell with duplicated material suffers division, originating two exact same daughter cells. Mitosis occurs in only one phase.
In the prophase, it occurs chromosomes condensation and nuclear membrane breaks. During the metaphase, fibers of the spindle drive chromosomes and take them to the cell equatorial plane, where they line up. Each chromatid joins with a microtubule of opposites poles, but sister chromatids are still together.In the Anaphase, enzymes are activated to break the bonds and separate the chromatids, which migrate to the opposite poles, helped by the single apparatus fibers.In telophase, the duplicated chromosomes are already in the corresponding poles, and the nuclear membrane forms again in each pole.Finally, occurs cytokinesis, which involves the invagination of the cell membrane and cytoplasmic division.The person who will give me answer the earliest i will mark him/her brainliest

19. Washing will help remove bacteria from the surface of fruits and vegetables. One should not ever consume bacteria, which is why we wash our fruits and vegetables.
20. Biological control is the beneficial action of parasites, pathogens, and predators in managing pests and their damage. Biocontrol provided by these living organisms, collectively called “natural enemies,” is especially important for reducing the numbers of pest insects and mites.
21. You need to get pictures of agricultural machines (machines used for farming).
22. Microorganisms are broadly classified in four groups: Bacteria, fungi, protozoa, and algae.
23. Viruses are even smaller than bacteria, because they aren't even a full cell. They are simply genetic material.
24. The culture of bacteria called “Lactobacillus delbrueckii” produces yogurt.
25. Yeast has commonly been used for the making of bread, for example.
26. In anaerobic respiration yeast breaks down glucose, forming ethanol and carbon dioxide as its waste products. When the glucose is nearly used up, and provided that oxygen is present, yeast uses the ethanol as a respiratory substrate to produce carbon dioxide and water in aerobic respiration.
27. Typically, the term is used to describe an infectious microorganism or agent, such as a virus, bacterium, protozoan, prion, viroid, or fungus. A pathogen may also be referred to as an infectious agent, or simply a germ.

What is an example of an advantageous trait? (1 point)
O Elephants are being born without tusks, in response to pressures from poaching for ivory.
Peacocks are brightly colored to attract mates, though their feathers make them more susceptible to
predation.
O Black bears are not always black, but come in various shades including blonde, cinnamon, and brown
A large proportion of Ireland's population has red hair, more than anywhere else in the world.
Answer:
The correct answer is a) Elephants are being born without tusks, in response to pressures from poaching for ivory.
Explanation:
Individuals with advantageous traits are more likely than others of their species to survive and reproduce. This is why the elephants would be the answer, as opposed to the peacocks. The brightly colored peacock feathers make them more susceptible to predation, which would actually decrease their chance for survival.
An example of an advantageous trait is the Elephants are being born without tusks, in response to pressures from poaching for ivory.
What are adaptive characteristics of animals?All characteristics that suit their possessors to something are generally said to be adaptive and allow living beings to develop a certain harmony with the environment, thus adjusting themselves for their survival in a given place.
With this information, we can conclude that an example of an advantageous trait is the birth of tusked elephants in response to pressures from poaching ivory.

Which of the following is the body's first line of defense against disease?
Which are likely effects of an increase in the concentration of atmospheric carbon dioxide on both the global climate and carbon cycle?
Answer:
This question lacks options, however, it can be answered based on general understanding. The answer is;
It leads to an increase or rise in the global atmospheric temperature, called GLOBAL WARMING.
Explanation:
Carbon dioxide (CO2) is an atmospheric substance (gas) that has the ability to trap and emit heat. This property makes it a renowned green house gas. An increase in the amount of CO2 in the atmosphere will lead to a rise in the Earth's global temperature.
This process whereby the atmospheric temperature of the Earth increases is called GLOBAL WARMING, and it affects the climate of the world and carbon cycle of the Earth.
