Answer:

The barrel will crash down after falling over a waterfall.

Explanation:

The force of the barrel and the gravity that brings down the barrel will make the barrel fall at a high speed, and when it hits the water, it will go through to the bottom and break apart into pieces.

what are the scientist doing incorrectly? what could they do to make their work in the lab safer? why is it important to follow

Andrews [41]

Answer:

What the scientist is doing incorrectly is disposing of a chemical or biological waste in the common sewer.

Explanation:

One of the most important biosecurity measures is the proper disposal of chemical and biological waste. What the shown scientist is doing incorrectly is disposing of potentially harmful substances in a normal sewer.

<h3>What could he do to make their work in the lab safer? </h3>

The main thing that must be done to maintain a safe laboratory is to perform proper disposal of chemical or biological waste, which must be placed in airtight containers and transported to a location for safe disposal.

<em>Chemical waste is usually taken to a landfill where it can be neutralized. </em>
<em>Biological waste is transported to incinerators for complete disposal. </em>

<h3>Why is it important to follow these procedures? </h3>

Following these procedures is important to avoid chemical or biological contamination of both the environment and people.

Dina is a paleoclimatologist. she wants to review documents to assess climate data for her hometown. which historical documents

lana66690 [7]

Newspaper articles and farmers harvest yield record are the documents should Dina examine in order to assess this climate data.

Among atmospheric scientists is a group known as paleoclimatologists. There were 11,800 workers in this field in 2014, albeit not all of them were climatologists or paleoclimatologists, according to BLS data. With 40% of the workforce, professional, scientific, and technical services was the main employer of atmospheric scientists.

<h3>What level of education is required to work as a paleoclimatologist?</h3>

Your future work as a paleoclimatologist will involve a lot of biology, physics, and other hard sciences, thus there are lots of degree programs that mix these fields with the environment. Environmental biology and environmental chemistry are two examples of such options.

<h3>How far into the past can paleoclimatology take us?</h3>

Paleoclimatology makes extensive use of polar ice sheets and ice caps as well as mountain glaciers. Data from ice-coring efforts in the ice caps of Greenland and Antarctica date back over 800,000 years in the case of the EPICA project, or several hundred thousand years.

<h3>Why is paleoclimatology essential and what does it entail?</h3>

Our knowledge of Earth's climate depends on the science of paleoclimatology. Scientists can create models to help predict how rising carbon dioxide levels and other changes can affect the climate of Earth in the future as they become more aware of how climates have been influenced in the past.

What is recombination and how does it work? is it the same thing as crossing-over? if an organism practiced self-fertilization,

Sever21 [200]

Recombination is the method by which organisms can randomly assort their genotypes amongst each other to create offspring with a different haplotype than either of its parents. This can be done by either copying sequences from one homologous chromosome to another (no physical exchange) or crossing over (physical exchange.
Crossing over is a mechanism in eukaryotes by which recombination can occur, in which the two homologous chromosomes contributed by both parents literally cross over and break at certain points to exchange certain sections of the chromosomes amongst each together.
Self fertilizing organisms typically do not produce offspring that are genetically identical. However, this has an inbreeding effect on its offspring, since it is recombining from the same genotype and so has a higher chance of producing homozygous offspring. This is very detrimental for mammals and some eukaryotes, but in some other organisms such as bacteria, homozygosity is typically not an issue.

Geckos and some other animals can climb smooth surfaces. Which of these explanations of this observation do you think is most re

miss Akunina [59]

The gecko's feet contain molecules that are attracted to the molecules on the surface.

Geckos are lizards which belongs to reptile group. They are found in warm climatic regions of the world. Geckos and some other animals can climb smooth surfaces because of presence of Van der waal forces of attraction between the molecules of gecko's feet with molecules of the surface. The force of attraction is generated due to fluctuations or differences in charge present in molecules of feet and that of surface. The charge fluctuations generally comes into sync and generate attractive force.

<h3>What are the features of Geckos ?</h3>

Most geckos are small, soft-skinned reptiles that are often nocturnal in behaviour. A small, robust body, a big head, and often well-developed limbs are other features they have. Each limb's tips are frequently fitted with digits that have adhesive pads.

The gecko possesses a variety of adaptive traits that help it avoid or confound predators. If a predator catches the gecko by the tail, the tail can be cut. One of the most well-known characteristics of the species is this. Some geckos may also alter their colour to better fit their surroundings.
