To allow DNA to enter bacterial cells, electrical pulses can be applied to the cells in a method called what?
A. Electroporation
B. Transduction
C. Ligation
D. Conjugation
Answer: Electroporation
Explanation: Electroporation, or electropermeabilization, is a microbiology technique in which an electrical field is applied to cells in order to increase the permeability of the cell membrane, allowing chemicals, drugs, or DNA to be introduced into the cell (also called electrotransfer).
Answer:
A
Explanation:
Electroporation

How does the structure of the muscle cell relate
the function?
Answer:
Skeletal muscle cells are arranged in bundles of linear fibers. ... These are thin strands made of the proteins actin and myosin that perform muscle contraction. The elongated shape of muscle cells allows the contraction proteins to line up in an overlapping pattern that makes muscle flexing possible.

You examine an epithelial cell (skin cell) and notice the chromosomes are visible however it appears there are two nuclei in the cell. What is the best explanation for this observation?
a) the cell has just gone through the S –phase of the cell cycle so there is double the amount of DNA
b) the cell has just gone through telophase but not cytokinesis
c) the cell has gone through meiosis I and is preparing for meiosis II
d) the cell is in G1 and is preparing for DNA synthesis
Answer:
The best explanation if we observe an epithelial cell with chromosomes are visible and two cell nuclei is that the cell has just gone through telophase but not cytokinesis (option b).
Explanation:
A somatic cell, when found in mitosis, exhibits the chromosomes distributed in both poles and the outline of two nuclei in the telophase phase, just before cytokinesis.
In mitotic telophase:
Chromatids, which are chromosomes, are found in the cell poles. It initiates the formation of the nucleus membrane. The chromosomes begin to turn into chromatin. Disappearance of the mitotic spindle, duplication of organelles and cytoplasmic invagination.The division and differentiation of the nuclei in telophase is called karyokinesis. Later, cytokinesis occurs, where the daughter cells are separated.
The other options are not correct because:
a and d. In the other phases described, S and G1, no chromosome distribution is observed at the poles.
c. A somatic cell does not experience meiosis.

. Fossil fuels are formed in the geological past from the remains of living organisms. Petroleum products, such as coal and natural gas are considered fossil fuels. Why are these types of fuels considered NONrenewable?
Answer:The types of fuels are considered non renewable because you could run out of the fuels quickly, but it would take over a million years just to renew the fuel
Explanation:
The types of fuels are regarded as non-renewable since they might swiftly run out while taking over a million years to replace them.
What are non renewable resources?Non renewable resources are defined as a natural resource that cannot be easily replaced by other natural processes quickly enough to meet demand. Coal or natural gas waste results from the use of non-renewable energy sources. This necessitates increased energy use and environmental protection.
The components of fossil fuels are decaying plants and animals. We rely on those fuels to heat our houses, operate our cars, supply electricity to us, and power manufacturing and industry. Since the creation of fossil fuels requires hundreds or millions of years, they are regarded as non-renewable resources. They cannot be instantly reused after being used.
Thus, the types of fuels are regarded as non-renewable since they might swiftly run out while taking over a million years to replace them.

Why do third level consumers gain was energy from their food
Answer: Why do third level consumers gain was energy from their food?
Explanation: It rarely happens, so often the tertiary consumers do not get eaten. Also, as tertiary consumers eat the primary and secondary consumers, they receive 10% of their energy from the producers. ... There are few omnivores/third-level consumers, because most third-level consumers eat only meat, since it's very tasty to them.

c
Explanation:
metaphase
As prometaphase ends and metaphase begins, the chromosomes align along the cell equator. Every chromosome has at least two microtubules extending from its kinetochore — with at least one microtubule connected to each pole.

One in that phylum of animals is mammals, which includes lions and howler monkeys.
Answer:
I think domain or family but I think domain more.
Explanation:
One domain in that phylum of animals is mammals, which includes lion and howler monkeys.
What is domain?
A taxonomic rank called a domain is used to categorize living things. A domain is the highest level of classification in biology, just below a kingdom. Eukarya, Bacteria, and Archaea are the three domains. Eukarya are multicellular organisms, whereas Archaea and Bacteria are single-celled.
On Earth, life can be found in four different domains: the domains of bacteria, archaea, eukarya, and viruses. Each domain has its own distinctive qualities. Single-celled organisms without a nucleus are known as domain bacteria.
Therefore, One domain in that phylum of animals is mammals, which includes lion and howler monkeys.

Explanation:
Globe displays Earth's curved surface on a flat model.
What is Globe?It's clear that whoever said "it's a small world" has never attempted to leave it. In actuality, the size of the globe is rather astounding, and figuring out just how massive it is took many thousands of years.
Our estimations have evolved over time, from astronomers discovering that the Earth was round (and not a flat disc, cube, or ziggurat) to the first successful attempts at circumnavigating the planet.
And the development of modern astronomy, together with advancements in science and the ability to see Earth from space, has undoubtedly been helpful.
