Answer:
Eukaryotic cells are believed to be evolved more recently than prokaryotic cells.
Explanation:
The statement about eukaryotic cells is NOT true - Eukaryotic cells are usually smaller than prokaryotic cells
Cells are fundamental units and are mainly two types eukaryotic cells and prokaryotic. There are various structural and functional differences and similarities found in them.
Prokaryotes and eukaryotic cells have the following difference:
Prokaryotic cells lack a true nucleusProkaryotic cells lack other membrane-bound organelles.Eukaryotic cells have more organelles, enzymes, and molecules, therefore, prokaryotic cells are simpler.Prokaryotic cells are comparatively smaller than eukaryotic cells.Prokaryotic cells are evolved before eukaryotic cells.Thus, the statement about eukaryotic cells is NOT true - Eukaryotic cells are usually smaller than prokaryotic cells

What is subduction and what causes it?
Answer:
Subduction is a geological process that takes place at convergent boundaries of tectonic plates where one plate moves under another and is forced to sink due to high gravitational potential energy into the mantle. Regions where this process occurs are known as subduction zones.
Explanation:
explain how darwin's journey to the galapagos islands contributed to his creation of the theory of evolutions.
Explanation:
During his visit to the islands, Darwin noted that the unique creatures were similar from island to island, but perfectly adapted to their environments which led him to ponder the origin of the islands' inhabitants.
Among those that struck Darwin so greatly were the finches that are now named in his honor. Darwin would later base some of his thought from the supposing that these finches were all descendents of the same lineage.

Why do genes in eukaryotic cells have introns?
Answer:
Introns are crucial because the protein repertoire or variety is greatly enhanced by alternative splicing in which introns take partly important roles. Alternative splicing is a controlled molecular mechanism producing multiple variant proteins from a single gene in a eukaryotic cell.
Explanation:
Describe some of the properties of water and explain how the structure of water is responsible for these properties.
Answer:
The main properties of water are its polarity, cohesion, adhesion, surface tension, high specific heat, and evaporative cooling. A water molecule is slightly charged on both ends. This is because oxygen is more electronegative than hydrogen. ... The stream of water bends due to the polarity of water molecules.

organelle that must be broken is the________
Answer:
The correct answer is - cell membrane.
Explanation:
Cell membrane or plasma membrane is the outer structure that enclosed the cell-matrix and cell organelles and acts as a barrier to the substances and things to move in or out of the cell and allows only specific substances and molecules to move in and out of the cell.
If the cell membrane is not performing its function properly it might result in blocking the various nutrients and other essential molecules to move in and metabolic substances to move out of the cell.

A student observes that a plant has droopy leaves and stems and infers that the rate of photosynthesis has slowed in the plant. Which statement provides evidence to support the student’s inference?
Answer:
A. The water pressure in the plant's vacuole is low, and without water, the chloroplasts cannot convert carbon dioxide to glucose during photosynthesis.
Explanation:
Photosynthesis occurs on chloroplasts which are located on the surface of leaves. Photosynthesis is the conversion of carbon dioxide, water, and light energy to produce glucose and oxygen for plants.
The vacuoles inside the plant's cell contain stored food and absorb water through osmosis. Water in the vacuole has more solutes than water outside the vacuole. This causes the Turgor Pressure which the vacuole impacts on the plants. If the reverse becomes the case, water is lost from the vacuole causing it to shrink.
Flaccidity of the vacuole and the cell wall will cause the chloroplasts where photosynthesis occurs to shrink.

a. It produces the greatest change in high and low tides.
b. It produces the least change in high and low tides.
c. It produces semidiurnal tides.
d. It produces diurnal tides.
Answer: The combined gravitational pull of the Sun and moon cause high tides in the path of the alignment, meaning that low tides occur at ninety degrees from the path of the solar eclipse. Due to inertia, the high tides also occur on the opposite side of the Earth from the solar eclipse.
Explanation: it's a
During the process of photosynthesis, energy from the Sun is converted into A) chemical energy in the bonds of inorganic molecules B) chemical energy in the bonds of organic molecules like glucose C) enzymes used to produce inorganic molecules D) enzymes used to produce organic molecules
Answer:
b
Explanation:
Photosynthesis is the process of preparing food in the presence of sunlight, water, and carbon dioxide to yield sugar and oxygen.
The correct option is:
Option B. chemical energy in the bonds of organic molecules like glucose
The process of photosynthesis involves:
Photosynthesis is carried out by plants. The leaves are the primary site for photosynthesis. The chloroplasts present in the plant cells are primarily involved in photosynthesis. Photosynthesis involves the capturing of light energy and storing it in the form of bonds of organic molecules like glucose and starch. The process involves carbon dioxide, water, sunlight, and green pigment chlorophyll to carry out photosynthesis. The products of the process are oxygen and sugar molecules holding the energy.
Thus, the correct answer is option B.

"CRISPR" stands for Clustered Regularly Interspaced Short Palindromic Repeats, which are the hallmark of a bacterial defense system that forms the basis for CRISPR-Cas9 genome editing technology. In the field of genome engineering, the term "CRISPR" or "CRISPR-Cas9" is often used loosely to refer to the various CRISPR-Cas9 and -CPF1, (and other) systems that can be programmed to target specific stretches of genetic code and to edit DNA at precise locations, as well as for other purposes, such as for new diagnostic tools. How can this tool be used to alter genes in various organisms?
Answer:
by designing short guide RNAs (sgRNAs) customized to target genes of interest in the cells of these species
Explanation:
The CRISPR-Cas9 editing system is a versatile and powerful genome engineering tool for editing genomes, which can be directed to alter almost any DNA sequence in order to modify gene function. This system consists of an endonuclease protein (Cas 9) that cuts DNA at specific sites guided by a short guide RNA (sgRNA), which binds by base complementarity to the target sequence. This sgRNA must be designed with efficiency and specificity to target genes of interest. In consequence, the CRISPR-Cas9 genome editing system produces DNA double-strand breaks which may be repaired by 1- error-prone nonhomologous end joining (NHEJ) or 2-homology-directed repair (HDR) DNA repair pathways. According to the DNA repair pathway that has been activated, it is possible to trigger genetic modifications in the cells of different species (i.e., plant cells, animal cells, human cells, etc).

about artificial selection, determine if YOU think the benefits of artificial selection outweigh the disadvantages.
PLEASE HELP!!!!
Answer:
What YOU think
Explanation:
That's what it asks, but here are some points to help you along your way: Artificial selection has brought about the extinction or overpopulation of certain species. This can be seen in the avocado or banana industry. Consumers like the smaller, sweeter species of avocadoes. This caused that species to explode and the old ones to become endangered as farmers grew only that type and bred them selectively. Consumers like the smaller, less mushy, less sweet banana species, so now an amazing species of banana is extinct because the forests that used to have them now no longer exist or were changed to grow only that type of banana. Flip it to the animal side, and it's the same story. Those turkeys that the president "Saves" every year? because of artificial selection, that turkey dies a few weeks later because he grew too plump. Why? Because those turkeys are artificially selected to grow much larger than a normal turkey, and their lifespan is not in mind as they are grown for meat. Also, I hope all of this work gives me brainliest :/
