Answer:

They both had a tail as an embryo.

Explanation:

Both human and dogs have tail as an embryo. Temporary tail-like structures are present in the human embryo. These tail like structure develop around the fifth or sixth week of gestation, having about 10 to 12 vertebrae and removed when it reached to its full development stage while on the other hand, tail present in dog's embryo also developed with time and we can see when the dog baby is fully formed.

Answer:

They both had a tail as an embryo.

Their arm and leg structure is similar but may have a different function.

Explanation:

Vestigial structures are those body parts that have lost or reduced their original function during the evolution of a species. These vestigial structures might be found in many animals, including human beings. Vestigial structures were plenty functional for common ancestors. But with evolution, they degenerated, stunted, and became rudimentary for some of the new species.  

During the first 4 months of embryogenesis, all mammals have a tail at some point in their development. Dogs develop this structure and keep it during their whole lives, but humans lose it with time during embryogenesis. The tail disappears, and its forming vertebras get fussed with each other composing the coccyx, which represents a vestigial structure. This tailbone is the remnant of a missing tail.

In many animals, the function of the tail is to stabilize, equilibrate and mobilize. But in humans, the coccyx, located at the end of the vertebral column, has lost this original function.

The fact that whales, humans, and dogs all have the same bones in the same order, but they matured differently in later embryological development, is an example of homologous characters.  

Homologous characters have the same fundamental structures. They also share the same relations with adjacent structures, and they have the same embryological development.  

These structures might show variations between organisms exhibiting them, according to their function and to the environment in which the organism lives.  

These homologous characters are common in organisms related and that share a common ancestor.

Short term atmospheric conditions give information regarding the weather in an area and Long-term precipitation and temperature data can give an indication of the climate of an area, both statement true.

Weather is the collective name for the momentary properties of the lower atmosphere, including precipitation, temperature, humidity, wind speed, direction, and atmospheric pressure. The possibilities are endless: it may be bright, cloudy, rainy, foggy, chilly, hot, windy, stormy, snowy, etc.

Seasons, documented climate cycles, or volcanism are frequently to blame for short-term climate change, which affects shorter timescales.

Long-term climate change affects longer time periods and may be brought on by human activity, variations in the sun's output, or a sluggish recovery from the Flood.

Therefore, weather refers to atmospheric circumstances for a brief period of time, whereas climate refers to long-term, predictable atmospheric conditions.

Answer:

The first answer is rainfall, and the second answer is the last one

Explanation:

1.

Rainfall is measured with a rain gauge in inches/millimeters - Most modern rain gauges generally measure the precipitation in millimetres in height collected on each square meter during a certain period, equivalent to litres per square metre. Previously rain was recorded as inches or points, where one point is equal to 0.254 mm or 0.01 of an inch.

2.

Climate is the weather conditions prevailing in an area in general or over a long period. The other 3 describe the weather conditions in a place for just a week, or day while climate is measured annually (basically over a long time)

What else is produced during the combustion of propane, C3H8 is H20, but to understand this reaction, we need to know.....

When an oxidizer sold as a fuel, it is also called liquefied petroleum gas (LPG), which is a mixture of propane with small amounts of

As an odorant to prevent the normally odorless propane from going unidentified. when in leaks. It is used as fuel for stoves and in car engines.

The combustion of propane is a typically exothermic reaction with the evolution of heat:

C3H8 + 5 O2 → 3 CO2 + 4 H2O

With this information, we can say that the combustion product of propane is H2O.

Answer:

Some physical characteristics, such as the color of the human skin or eyes, are controlled by at least two genes. These traits are known as polygenic traits. The number of genes that determine the color of the iris is unknown, but the most significant of them are found in Chromosome 15 and they are named OCA2 and HERC2. These genes are associated with the production of melanin.

Explanation: Polygenic inheritance describes the inheritance of traits that are determined by more than one gene. These genes, called polygenes, produce specific traits when they are expressed together. Polygenic inheritance differs from Mendelian inheritance patterns, where traits are determined by a single gene. Polygenic traits have many possible phenotypes (physical characteristics) that are determined by interactions among several alleles. Examples of polygenic inheritance in humans include traits such as skin color, eye color, hair color, body shape, height, and weight.

two long polynucleotide chains

A DNA molecule consists of two long polynucleotide chains composed of four types of nucleotide subunits. Each of these chains is known as a DNA chain, or a DNA strand. Hydrogen bonds between the base portions of the nucleotides hold the two chains together

Molecules of DNA are composed of long chains of nucleotides.

Nucleotides are the building blocks of DNA  and RNA adenine (A), thymine (T), guanosine (G), and Cytosine (C. In RNA, uracil (U) is present instead of thymine.

The pentose sugar is the ribose sugar in RNA and deoxyribose sugar in DNA. In deoxyribose sugar, oxygen is absent from the 3' carbon.

Phosphate groups are attached through the 5-C of pentose sugar by an ester bond. One polynucleotide chain is formed when the phosphate of one nucleotide forms a phosphodiester bond with the sugar of another nucleotide.

A double-stranded structure is formed by base pairing between nucleotides. The adenine binds to thymine by two hydrogen bonds and guanine binds to cytosine by three hydrogen bonds.

Therefore the molecules of DNA are composed of long chains of nucleotides.

An illness called food poisoning is brought on by consuming tainted food. Most people recover without treatment in a few days and it's typically not dangerous.

The capacity of a rock or other substance to let the passage of water is known as permeability, hence option c is correct.

Groundwater may readily flow through permeable materials because the pore space is linked throughout the rock or sediment. Mud and clay are examples of materials with great porosity yet very limited permeability.

An aquifer is a water-bearing rock that easily transfers water to wells and springs, the aquifers may be dug into and water pumped out.

Therefore, water that falls onto land surfaces flows into water bodies or it may be soaked in the ground, this water flows through the soil and rock which are permeable, hence option c is correct.

Answer: A karyotype test examines these dividing cells. The pairs of chromosomes are arranged by their size and appearance.

Explanation:

In a karyotype, the arrangement of chromosomes is generally done in the order of size, that is, from largest to smallest.

It is the number and appearance of chromosomes. It comprises the length of the chromosomes, the banding pattern, and the position of centromere.

In a human karyotype, the body chromosomes or autosomes are usually aligned in approximate order of size from largest to smallest, that is, from chromosome 1 to chromosome 22.

However, the chromosome 21 is shorter in comparison to chromosome 22. The arms of the chromosomes protruding from either end of the centromere may be classified as long or short, based upon their relative lengths.

The long arm is abbreviated as q and the short arm as p. Each arm is subdivided further and is designated by a number. The locations on chromosomes can be illustrated by using the naming system.

Thus, in a karyotype, chromosomes are arranged on the basis of their size, that is, from largest to smallest.
