A researcher places part of a plant cell in a beaker of water. She observes that the plant leaves release bubbles of gas when she shines a light on the beaker. The leaves do not release gas when the beaker is placed in the dark. Based on her observations, which of the following is the most logical inference?

Answer:

When the ovum is fertilized by pollen tube core, it starts a process of differentiation which leads to the seed generation. In angiosperms, the fruit formation occurs from the ovary of flowers, simultaneously and in a similar way to the formation of seeds.

Answer:

Speed of both will be decreases when they travel through the medium of water.

Explanation:

Both sunlight and radio wave has the same speed in vacuum but both speed will be decreases when they travel through the medium of water because the consistency of water is more than air which make hard to travel for sunlight and radio wave. The speed of sunlight is slightly decreases but the radio wave can't go too far in the water and finally stops so we can say that sunlight can travel through water but radio wave none.

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:

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.

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."

Hope this helps.

Explanation:

Species

A group of organisms that can reproduce and produce fertile offspring (children that can reproduce themselves)

Trait

Characteristic of an organism (body part, behavior, chemical, produced)

Variation

Differences in trait expression

Inherited trait

Trait passed from parent to children (offspring)

Acquired Trait

Traits learned by/changed in an individual from interaction with the environment

Protein

A special type of biological molecule (only found in organisms) that organisms use to build, maintain, and operate the cells/tissues/organs of their bodies. (Like a prepared meal)

DNA

The biological molecule that serves as the chemical instructions or blueprints for building all the proteins an organism needs to build its body and survive. (Like words in a cookbook)

Gene

A section of a DNA molecule that serves as the instructions to build one protein. (Like one recipe in a cookbook)

Chromosomes

Large packages of coiled DNA molecules that are passed from parents to children. (Like different chapters on a cookbook)

Pollen

Flowering plant sperm (male sex cell)

Answer: yes.

Explanation: Non-renewable resources can be depleted and cannot be replenished. Water is a natural resource which is not only found on the surface of the earth in rivers, oceans, lakes, and streams but also underground. Water is a renewable resource.

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.

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:

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:

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 : In radioactive decay, the half-life is the length of time after which there is a 50% chance that an atom will have undergone nuclear decay. It varies depending on the atom type and isotope, and is usually determined experimentally.

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.

6 CO2 + 6 H2O + light  →  C6H12O6 + 6 O2

Carbon Dioxide + Water + Light       Glucose + Oxygen
