The chemical formula of a compound describes the elements the compound contains and the
A.pH of the compound.
B.conduction of the compound.
C.ratio of elements in the compound.
D.ratio of neutrons to protons in each element.

Answers

Answer 1

Answer:

C.ratio of elements in the compound.

Explanation:

A compound is a substance that constitutes two or more elements in a defined proportion. A chemical compound is different from another compound in what it contains i.e. elements. A chemical formula shows the elements contained in a specific compound. For example, the chemical formula of sodium chloride (NaCl) shows us that it contains Sodium (Na) and Chlorine (Cl) elements as represented by symbols.

In addition to this, a chemical formula also shows the ratio of each element that makes up the compound. An element can have more than one atom in a compound. For example, CaCl2 is the chemical formula for Calcium chloride and it shows is that the ratio of Calcium (Ca) to Chlorine (Cl) is 1:2.

1156 g/L
= ________ kg/mL

Answers

The Answer is 0.001156.

To convert g/L to kg/mL, we need to divide the value of g/L by 1000. Therefore:
1156 g/L = 1.156 kg/L
Since 1 L is equal to 1000 mL, we can convert kg/L to kg/mL by dividing by 1000:
1.156 kg/L = 1.156/1000 kg/mL
1.156/1000 kg/mL = 0.001156 kg/mL
Therefore, 1156 g/L is equal to 0.001156 kg/mL.

1.Which description matches the histogram of the population 50 generations ago?A.Most of the newts had

Answers

Answer:

B for the first answer

Explanation:

The histogram of the population 50 generations ago showed that the majority of newts had low-poison level traits and very few had high-poison level traits. Now, the histogram of the population shows that the majority of newts have high-poison level traits and very few have low-poison level traits. So, the correct option for 1 and 2 are A and B.

What is Histogram?

A histogram is a graphic depiction of a frequency distribution with continuous classes that has been grouped. A series of rectangles with bases equal to the distances between class boundaries and areas proportional to frequencies in the associated classes make up the area diagram.

Since the base in such representations spans the spaces between class boundaries, every rectangle is neighboring. For above given example, The population's histogram from 50 generations ago revealed that most newts possessed low-poison level features, while just a small number possessed high-poison level traits. Now, the population's histogram reveals that most newts exhibit features associated with high poison levels, whereas relatively few exhibit traits associated with low poison levels.

So, the correct option for 1 and 2 are A and B.

Write a 4 paragraph essay explaining the types of asexual reproduction and advantages and disadvantages of each. Include descriptive text in each and diagrams at the end if you would like.

Answers

Answer:

Explanation:

Asexual reproduction is a mode of reproduction in which a new offspring is produced by a single parent. The new individuals produced are genetically and physically identical to each other, i.e., they are the clones of their parents.

Asexual reproduction is observed in both multicellular and unicellular organisms. This process does not involve any kind of gamete fusion and there won’t be any change in the number of chromosomes either. It will inherit the same genes as the parent, except for some cases where there is a chance of a rare mutation occurring.

The term “fission” means “to divide”. During binary fission, the parent cell divides into two cells. The cell division patterns vary in different organisms, i.e., some are directional while others are non-directional. Amoeba and euglena exhibit binary fission.

It is one of the simplest and uncomplicated methods of asexual reproduction. The parent cell divides into two, each daughter cell carrying a nucleus of its own that is genetically identical to the parent. The cytoplasm also divides leading to two equal-sized daughter cells. The process repeats itself and the daughter cells grow and further divide.

Fragmentation is another mode of asexual reproduction exhibited by organisms such as spirogyra, planaria etc. The parent body divides into several fragments and each fragment develops into a new organism.

Regeneration is the power of growing a new organism from the lost body part. For eg., when a lizard loses its tail, a new tail grows. This is because the specialized cells present in the organism can differentiate and grow into a new individual. Organisms like hydra and planaria exhibit regeneration.

Budding is the process of producing an individual through the buds that develop on the parent body. Hydra is an organism that reproduces by budding. The bud derives nutrition and shelter from the parent organism and detaches once it is fully grown.

Asexual reproduction in plants occurs through their vegetative parts such as leaves, roots, stems, and buds. This is called vegetative propagation. For example, potato tubers, runners/stolon, onion bulbs, etc., all reproduce through vegetative propagation.

Spore formation is another means of asexual reproduction. During unfavourable conditions, the organism develops sac-like structures called sporangium that contain spores. When the conditions are favourable, the sporangium burst opens and spores are released that germinate to give rise to new organisms. In asexual reproduction, a single cell is divided to produce offspring. Simple cell-by-cell division is not possible in multicellular organisms. Most of the multicellular organisms have a complex body design. They have a higher level of organization like tissues, organs and organ systems. Thus, they need a special mode for reproduction.

Explain how scientists use geologic time to determine the age of landforms. (3 points)

Answers

Answer: there are three different methods of determining the age of a landform.

1 radiation measurement

2 stratigraphic superposition

3 the fossil record

by using these or a combination of these they determined that the earth is around 4.6 billion years old. and this is where the big bang theory comes into play.

To determine the relative age of different rocks, geologists start with the assumption that unless something has happened, in a sequence of sedimentary rock layers, the newer rock layers will be on top of older ones. This is called the Rule of Superposition. ... With absolute age dating, you get a real age in actual years

A small gap is left between the rails in the railway track. Analyze the reason.

Answers

Answer:

There could be several possible reasons for a small gap between rails on a railway track, such as:

1. Expansion joints: Railways are designed to allow the tracks to expand and contract with changes in temperature. To accommodate this expansion, small gaps are left between the rail ends and filled with expansion joints or plates.

2. Wear and tear: Over time, the rails may experience wear and tear due to heavy loads, weather conditions, and other factors. As a result, small gaps can appear between the rails.

3. Maintenance: During maintenance activities, rail tracks may be adjusted or replaced, which could lead to small gaps between the rails.

4. Environmental factors: Environmental factors such as soil shifts, earthquakes or other natural disasters can also affect the alignment of the rails, leading to small gaps.

These are some of the possible reasons for a small gap between the rails on a railway track.

Answer:

The small gap left between the rails in a railway track is intentional and serves a specific purpose. This gap is known as the rail joint, and it allows for the expansion and contraction of the rails due to changes in temperature. When the temperature changes, the metal rails will expand or contract, and if they were joined together tightly, they could buckle or become deformed, which could be dangerous for trains passing over them. The rail joint allows the rails to move slightly and prevent damage to the track.

Additionally, the rail joint also allows for maintenance and repairs of the track. If there were no gap between the rails, it would be challenging to replace a damaged rail or perform routine maintenance, such as tightening bolts or lubricating joints. With the rail joint, maintenance personnel can easily access and work on the track.

Overall, the small gap left between the rails in a railway track is intentional and serves a crucial function in ensuring the safety and reliability of the track.
