Which tissue conducts water from the stem?
Xylem is a kind of vascular tissue found in plants that transports nutrients, water, and dissolved minerals from the roots to the rest of the plant while also acting as a structural support tissue system.
Water is transported from the roots to all parts of the plant by a stem structure called xylem, which takes the shape of a network of tubes. A complicated permanent tissue found in plants is called xylem. It is made up of vessels, tracheids, xylem fibres, and xylem parenchyma. They aid in the plant's water conductivity.
Xylem tissue is composed of a variety of specialized, water-conducting cells called tracheary components. Water and minerals must be transported from the roots to every area of the plant through the xylem tissue of plants.

during pcr, what three materials are mixed with the crime scene dna?
Three components which are frequently combined with the crime scene DNA sample during PCR (polymerase chain reaction) to amplify certain areas of the DNA are as follows:
Primers, Taq polymerase and Deoxynucleotide triphosphates (dNTPs)
Primers are short DNA sequences that anneal to certain sections of the target DNA. Primers are necessary for PCR because they serve as a starting point for DNA polymerase, which initiates DNA synthesis and amplifies the desired target sequence.
Taq polymerase: A DNA polymerase enzyme capable of surviving the high temperatures necessary for PCR. With each PCR cycle, Taq polymerase stretches the primers, duplicating the target DNA sequence.
Deoxynucleotide triphosphates (dNTPs) are DNA building components required by Taq polymerase to manufacture new DNA strands. These dNTPs are supplied in adequate quantities to the PCR reaction mix to promote DNA synthesis during each PCR cycle.

what happens to the access nutrients within the soil?
Mineral vitamins come from the soil. These vitamins are absorbed through the flowers roots whilst uptaking water.
Mineral vitamins are damaged up into macronutrients and micronutrients. The maximum essential number one macronutrients for flowers are nitrogen (N), phosphorus (P), and potassium (K). When plants are harvested, essential vitamins are eliminated from the soil, due to the fact they observe the crop and turn out to be on the ground. If the soil isn't always replenished with vitamins through fertilizing, crop yields will become worse over time. When flowers die, the vitamins locked up inside them are launched returned into the surroundings, laying the grounds for brand new increase and abundance. The breakdown of flowers is important to nature's potential for regeneration.

Explanation:
what would be the consequence if a cell were unable to replicate its dna
If a cell were unable to replicate its DNA, it would not be able to divide and produce two daughter cells with identical genetic material. This could have serious consequences for the organism as a whole.
For example, during development, cells need to divide and differentiate to form the various tissues and organs of the body. If DNA replication is impaired, the resulting daughter cells may not have the correct genetic material, leading to developmental abnormalities and possibly even death.
In adults, failure of DNA replication can lead to cancer. Mutations in genes that regulate DNA replication, such as tumor suppressor genes, can result in uncontrolled cell division and the formation of tumors.
In short, the ability to replicate DNA is essential for normal cellular function, growth, and development, and any impairment of this process can have significant consequences for the organism.

The statement is True (A). Circular fitness can only be gained by helping kin and not by helping unconnected individuals. Hamilton offered the main sapience for understanding the nature of tone- immolating geste.
He argued that natural selection favors inheritable success, not reproductive success per se and that individuals should carry clones of their genes to unborn generations. In a species of freak, one son frequently stays with her mama ( the queen) and helps her mama raise further sisters and sisters. Speciation can do without natural selection; for illustration, speciation results from cases of inheritable variation.

What is the meaning of feminism in biology?
Feminist biology is a biological approach that is concerned with the influence of gender values, the elimination of gender bias, and the overall significance of social values in biological research and activities.
Dr. Ruth Bleier of the University of Wisconsin-Madison (who produced the 1984 work Science and Gender: A Critique of Biology and Its Ideas on Women and inspired the university's endowed fellowship for feminist biology) was among those who launched feminist biology. It strives to advance biology by including feminist critique in subjects varying from the mechanics of cell biology and sex selection to the assessment of the meaning of words such as "gender" and "sex".
Generally, the area is vast and refers to the concepts underlying both biology and feminist praxis. These considerations make feminist biology debatable and contradictory to itself, particularly when it comes to biological determinism, in which descriptive sex terms such as male and female are intrinsically confining, or extreme postmodernism, in which the term "feminist" refers to the term "feminist biology."

the initial mechanism for repairing nucleotide errors in dna is ________.
The initial mechanism for repairing nucleotide errors in DNA is base excision repair (BER).
BER is a multi-step process that recognizes and removes damaged or incorrect nucleotides from the DNA sequence, before replacing them with the correct nucleotides.
In BER, a specialized enzyme called a DNA glycosylase recognizes and cleaves the bond between the damaged or incorrect base and the sugar-phosphate backbone of the DNA molecule, leaving an apurinic/apyrimidinic (AP) site. This site is then recognized by other enzymes, which remove the remaining sugar-phosphate backbone and replace the missing base with the correct one, using the complementary base pairing rules.
BER is an important mechanism for repairing single-base errors in DNA, such as those caused by chemical damage or errors during replication. However, other mechanisms such as nucleotide excision repair (NER) and mismatch repair (MMR) are also important for repairing larger-scale DNA damage and mismatches, respectively.
