Explanation:

Planarians are a group of Turbellaria, free-living flatworms that capture their food via a process of wrapping around it, entangling it in slime, and pinning it down before a prey into a gastrovascu lar cavity where free-living flatworms that capture extends from the mouth, bringing the prey into a gastrovascular cavity where free-living flatworms that capture extends from the mouth, bringing the digestion occurs.

Answer:

Alvin is propelled by _gas or diesel___ hydraulic thrusters and features an electrical system powered by lead-acid batteries.

Explanation:

Technically, this implies that Alvin is working on motor-assist mode, using a hybrid engine.  Alvin is, therefore, propelled by an internal combustion engine (given the presence of hydraulic thrusters) in addition to an electric motor, which uses energy stored in (lead-acid) batteries.  Alvin must be a robot.

Answer:

In the transcription of DNA to mRNA, for the DNA sequence 3'-AGGTCTCAC-5' corresponds to an mRNA sequence 5'-UCCAGAAGUG-3'.

Explanation:

Transcription is the process by which a strand of mRNA, needed to direct protein synthesis in the cytoplasm, is synthesized from a strand of DNA.

The sequence of nucleotides in the RNA chain depends on the sequence of bases in the DNA strand, being placed according to the complementarity of nitrogenous bases, where a purine is complemented with a pyrimidine.

In RNA, the thymine base is replaced by Uracil, the complementary base to adenine of DNA.

Answer:

what notes

Explanation:

correct answer is B; if the allele is expressed after reproduction has occurred.

The situation in which a gene pool contain an allele that causes a lethal disease is: (B) If the allele is expressed after reproduction has occurred.

When the allele is expressed after reproduction has occurred, individuals carrying the lethal allele can reproduce and pass on the allele before the disease is expressed. Since the disease may not manifest until later in life or after reproduction has occurred, the allele can persist in the gene pool without being selected against. Over generations, the allele frequency can remain relatively stable, leading to the presence of the lethal allele in the gene pool.

An allele can be defined as a variant form of gene. Alleles can exist in different forms due to changes in the DNA sequence. These changes can be substitutions, deletions, insertions, or other types of genetic mutations.

Answer:

Gravity

Explanation:

Percolation is the process of a liquid slowly passing through a filter. It's how coffee is usually made. Percolation comes from the Latin word percolare, which means "to strain through." Percolation happens when liquid is strained through a filter, like when someone makes coffee.

Evaporation-the process of turning from liquid into vapor.

Condensation-water which collects as droplets on a cold surface when humid air is in contact with it.

and gravity- Gravity is the force of attraction between two objects, and Earth's gravity pulls matter downward, toward its center. It pulls precipitation down from clouds and pulls water downhill. The warm water near the surface of the ocean heats up with sunlight and evaporates, keeping the water cycle in motion.

Answer:

Giant sequoias can grow more than 80 meters tall! molecules they need for growth using atoms from the water and air around them. ... Plants take in molecules from water and air around them to make different molecules that can be used for energy and growth.

There are two types of cell division: mitosis and meiosis. Most of the time when people refer to “cell division,” they mean mitosis, the process of making new body cells. Meiosis is the type of cell division that creates egg and sperm cells. Mitosis is a fundamental process for life.

Answer:

Increasing  carbon dioxide  concentration  increases the  rate of  photosynthesis  as carbon  dioxide (CO2) is a limiting factor.

Explanation:

Some limiting factors like carbon dioxide, temperature etc. influence the photosynthetic rate, which may end up reducing the potential amount of carbohydrate produced by photosynthesis. Carbon dioxide is important for this form of biosynthesis: it provides the inorganic carbon that is integrated into carbohydrate molecules.

The photosynthetic rate can be slowed by a decline in the concentration of available carbon dioxide.

Explanation:

Answer:

Some three billion years ago, the Earth's atmosphere was virtually devoid of oxygen. At about 2.4 billion years ago, oxygen was released from the seas as a byproduct of photosynthesis by cyanobacteria. Levels of the gas gradually climbed, reaching about one percent around two billion years ago.

Hope this helped, Have a Great Day!!

Answer:

Phenotype are physical traits a organism can inherit for example color, height, or body features are phenotype. Genotype are genetic traits that can be inherited for example personality, or behavior traits. So the primary difference between phenotype and genotype is that "phenotype are psychical characteristics while genotype is genetic."

Answer:

The correct answer is - bogs.

Explanation:

Bogs or boglands is a wetland that is made up of dead organic matter such as dead plants or parts of the plants like mosses, majority time it is a thick carpet of sphagnum moss. All these form spongy peat which is stagnant.

Most of the water present in this wetland comes from rainfall instead of runoff or streams from the groundwater which makes it a wetland with a shallow area of water-saturated soil. This wetland is known for its less photosynthesis.

Answer:

The landform marked with A is an ox-bow lake.

Explanation:

In the image, we can see a river and another fluvial landform right next to it. The river is meandering, moving through the plain in a zig-zag manner. The landform next to it has a half-circular shape, and it seems as it has been attached to the river until recently. In fact, the landform next to the river has been a part of the river until recently, but because of moving too far away from the base it became detached.

The landform in question is an ox-bow lake. This is a lake that has a short lifespan, and it usually has a half-circular shape, being just a few meters away from the river from which it formed. Initially, the ox-bow lake was actually part of the river and its meandering, but as the erosion was moving the water further and further away from the base of the river bed, the water was moving harder and harder, so naturally, the water moves in a direction where it is easier to do so. Little by little, the river starts to move in another direction, closer to its base, and the part of the meander that went too far away gets detached, thus forming an ox-bow lake.

Answer:

The function of the pollen tube is to lead sperm cells into the ovary.

Explanation:

In angiosperms, the pollen tube is a structure formed when the pollen grain comes into contact with the stigma and germinates, producing a tubal extension that is related to the embryonic sac where the female gametophyte is found.

The function of the pollen tube is to conduct the male gametophyte —which is found in the pollen— to the embryonic sac, in order to come into contact with the oosphere and produce fertilization.

The other options are not correct because the pollen tube:

Answer: to lead sperm cells into the ovary .

Explanation: There needs to be a way for the sperm cells formed by the pollen's generative nucleus to reach the egg cells that are found in the ovary.

Answer: oxygen

Explanation:

If the process illustrated in the diagram is interrupted by a chemical at point X, there would be an immediate effect on the release of oxygen gas.

Photosynthesis, the process by which light energy is transformed to chemical energy and results in the generation of oxygen and energy-rich organic compounds, takes place in the chloroplast, a structure found inside the cells of plants and green algae.

Close relatives of chloroplasts that are free-living are photosynthetic cyanobacteria; according to the endosymbiotic theory, these organisms are the ancestors of both chloroplasts and mitochondria, which are eukaryotic cells' energy-producing organelles.

Therefore, If the process illustrated in the diagram is interrupted by a chemical at point X, there would be an immediate effect on the release of oxygen gas.
