In the seventeenth century, Francesco Redi performed experiments using raw meat placed in jars.
• Half of the jars were covered, and half were left open,
• Redi noticed that the meat in the sealed jars did not have maggots, but the meat in the open jars did have maggots.
Redi concluded that only flies could make more flies,
.
Which part of the cell theory corresponds to Redi's findings?

Answer: B.

Answer:

As a cell increases in size, it usually does not make extra copies of DNA. If a cell became too large, an "information crisis" would occur. The cell has more trouble moving enough nutrients and wastes across the cell membrane.

Answer:

We are left with four haploid cells; each one genetically different from each other and the parent cell. 8. Describe the three ways meiosis produces genetic variability. We have seen that meiosis creates variation three ways: crossing over, mutations caused during crossing over, and independent assortment.

Answer:

Due to no jaws, no paired fins and scales on the body.

Explanation:

Pteromyzon fish is different from scolidon and labeo fishes because Pteromyzon fish is not a true fish. The main reason for this is that Pteromyzon fish is agnathous means having no jaws and it doesn't have paired fins and scales on their body while all these features are present on the body of  scolidon and labeo fishes so we can conclude from this discussion that Pteromyzon fish is different from scolidon and labeo fishes.

Answer:

1.Structural Divisions of the Nervous System. The nervous system can be divided into two major regions: the central and peripheral nervous systems. The central nervous system (CNS) is the brain and spinal cord, and the peripheral nervous system (PNS) is everything else.

2.Like the nervous system as a whole, the peripheral nervous system also has two divisions: the sensory division and the motor division. The sensory division of the PNS carries sensory information from the body to the central nervous system.

3.Sensory receptors with corresponding stimuli to which they respond.

Receptor Stimulus

Apmullae of Lorenzini (primarily function as electroreceptors) Electric fields, salinity, and temperature

Baroreceptors Pressure in blood vessels

Chemo receptors Chemical stimuli

Electromagnetic radiation receptors Electromagnetic radiation

Electroreceptors Electrofields

Hydroreceptors Humidity

Infrared receptors Infrared radiation

Magnetoreceptors Magnetic fields

Mechanoreceptors Mechanical stress or strain

Nociceptors Damage or threat of damage to body tissues (leads to pain perception)

Osmoreceptors Osmolarity of fluids

Photoreceptors Visible light

Proprioceptors Sense of position

Thermoreceptors Temperature

Ultraviolet receptors Ultraviolet radiation

Answer:

The gradual replacement of one plant community by another through natural processes over time.

Explanation:

Succession is a process dominated by plants, in which communities change as a function of the changes experienced by plant communities, that is, it is the natural evolutionary process by which some species gradually take the place of others less adapted to the environment. Ecological succession tries to predict the changes that occur in ecosystems over long periods of time, that is, the temporary directional change in the composition or structure of a community  over time.

Explanation:

Answer:

No. Gender traits in humans are largely determined by biophysical processes. There seems to be a vocal political faction that is trying to convince people in the name of liberty and equality that gender traits are completely learned, and therefore arbitrary. But this claim disagrees with scientific evidence. In general, boys play more with cars and girls play more with dolls not because their parents are perpetuating outdated gender stereotypes, but because their brain is telling them to. This fact does not mean that boys have to play with boy toys, or that boys who play with dolls aren't really boys. It is just a scientific observation about average behavior and its link to fetal development.

Telomeres

Hope this helps :)

Answer:

The answer is Telomeres.

Explanation:

Figure 4.19. Structure of a telomere. Telomere DNA loops back on itself to form a circular structure that protects the ends of chromosomes. Telomeres play a critical role in replication of the ends of linear DNA molecules.

Yes.

Explanation:

Yes, we must be kind to them and provide protection to them because they are also the member of this planet and they have equal right to live on this earth. These animals are very important for our environment and ecosystem because they provide various benefits to the human beings such as provides food, control harmful parts of ecosystem and increase beautification of the environment.

Answer:

Explanation:

Its either B or C, look closely at the question and at the answers, you can narrow it down from then.

A scientist is treating rice plants with a chemical that causes mutations. The possible benefit of this treatment is transgenic plants. Hence, the correct option is B.

A mutation is a change in the DNA sequence that makes up a gene. It can result from  errors in DNA replication or exposure to mutagenic agents such as chemicals or radiation, or from spontaneous changes.

Transgenic plants are the plants that have been genetically modified to express specific traits or traits that are not found in the original species. This is done by introducing foreign DNA or chemicals that change the plant's genome. This process is called genetic engineering.

Transgenic plants have become an important tool in agriculture and biotechnology, providing new opportunities for food production, environmental protection and economic growth. Hence, the correct option is B.

Answer:

B. Water seeped into the cracks and

expanded as it turned to ice

Explanation:

This is because as the glacier melts, water seeps into cracks on the rock underneath the glacier. As this water seeps into the cracks, it would be turned into ice. As the ice expands, it causes the rock to break up into pieces.

This process is called mechanical weathering.

Answer:

40kg

Explanation:

F=M*A

M=F\A

M=400\10

M=40kg

The mass of an object whose weight is 400 N and acceleration due to gravity is 10 m/s2​ is 40 kg.

The net acceleration that objects get as a result of the combined action of gravity and centrifugal force is known as the Earth's gravity, or g.

It is a vector quantity whose direction, strength, or magnitude match a plumb bob.

According to Newton's second law, an object's acceleration is inversely proportional to its mass and directly connected to the net force. An object's acceleration is determined by two factors: force and mass.

We know that,

F = m x g

m = f/g

Where,

F = force

m = mass

g = acceleration due to gravity

Given that,

F = 400N.

g = [tex]10m/s^2[/tex]

So,

m = 400/10

m = 40 kg.

Thus, the mass is 40 kg.

To confirm the ages obtained with magnetic records, and get an absolute age of the seafloor, scientists use the radioactive dating technique. When the lava solidifies at the ridges to form the new seafloor, radioactive elements coming from the mantle are trapped in it.

Answer:

Explanation:

Without any greenhouse gases, Earth would be an icy wasteland. Greenhouse gases keep our planet livable by holding onto some of Earth's heat energy so that it doesn't all escape into space. This heat trapping is known as the greenhouse effect. ... Putting so much new CO2 into the air has made Earth warmer.

Answer:

If we don't reduce the emissions of greenhouse gasses, we will end up have climate change. As the world heats up, the water levels rise, the polar ice caps melt and costal cities will end up under water at somepoint. Also animals that can't handle the temp changes can die.

Photosynthesis, the process by which green plants and certain other organisms transform light energy into chemical energy. During photosynthesis in green plants, light energy is captured and used to convert water, carbon dioxide, and minerals into oxygen and energy-rich organic compounds.
