Radioactive dating technique

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:

Knox County

Explanation:

i live in Nebraska

The oldest known species of horse found in Knox County in Nebraska, Eohippus, (genus Hyracotherium), also called dawn horse, is considered as oldest known species of horse, hence option 1 is correct.

The horse is a mammal considered a domesticated one-toed, hoofed mammal and belongs to the taxonomic family of Equus ferus, there is only one species of a domesticated horse but around 400 breeds developed for the improvement of their strength.

All horses are considered grazers, food like grasses and plants, and believed as herbivores in the tropic level, only plants not animals.

These animals generally use for domestication purposes by human beings for pulling carts and heavy materials.

Therefore, in Knox County of Nebraska, the oldest known species of horses is found, hence option 1 is correct.

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:

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.

The no. of heterozygous carriers = 0.0392

Explanation:

From the given information:

The incidence of this recessive disorder i.e. q² = 1/2500

q² = 0.0004

q = 0.02

From Hardy Weinberg's Equilibrium.

p + q = 1; &

p² + 2pq + q² = 1

∴

p + 0.02 = 1

p = 1 - 0.02

p = 0.98

So, the numbers of heterozygous carrier 2pq is:

= 2 × 0.98 × 0.02

= 0.0392

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.

The statements that accurately describe fermentation are cells may convert pyruvic acid to lactic acid, and fermentation is an anaerobic process. The correct options are B and D.

Fermentation is an anaerobic chemical process that breaks down molecules like glucose. More specifically, fermentation is the bubbling that happens during the creation of wine and beer, a procedure that has been around for at least 10,000 years.

It is different from aerobic respiration because it occurs in the absence of oxygen and aerobic respiration occurs in the presence of oxygen. The product of fermentation is lactic acid, which is produced from pyruvic acid.

Thus, the correct options are: B, Cells may convert pyruvic acid to lactic acid, and D, Fermentation is an anaerobic process.

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.
