Biology

Law Incorporation [45]3 years ago

Answer:

The sex chromosomes are referred to as X and Y, and their combination determines a person's sex. Typically, human females have two X chromosomes while males possess an XY pairing. This XY sex-determination system is found in most mammals as well as some reptiles and plants.

Men determine the sex of a baby depending on whether their sperm is carrying an X or Y chromosome. An X chromosome combines with the mother's X chromosome to make a baby girl (XX) and a Y chromosome will combine with the mother's to make a boy.

dedylja [7]
1 ) The first terrarium was developed by botanist Nathaniel Bagshaw Ward in 1842. He was interested in studying insect behaviour. Once he accidentally left one of his bug jars open. A fern spore in the jar sprouted, grew and germinated into a new plant. This is how the first terrarium had been created.

2 ) <span />Because of the different conditions within, terrariums there are two, which can be classified as closed and open. Closed terrariums have a lid to enclose the plants entirely within the glass container. Open terrariums do not require a lid.​

Sorry working on this right now as well, and I don't have the others yet :(

mel-nik [20]

Answer:

Three types of population distribution:

Clumped.

Random.

Uniform.

Explanation:

1. Clumped:

This is the most common pattern of population dispersion.

organisms are clustered together in a group.

This may reflect the patchy distribution of resources in the environment.

2. Random:

This is a typical distribution where individuals do not interact strongly.

The organism has unpredictable distribution.

3. Uniform:

This is the typical environment where individuals compete with each other for scarce resources like water in the desert.

organisms are evenly spaced over the area they occupied.

If the efficiency of a gasoline engine is 25%, what happens to the missing 75% of the energy in the fuel?
hram777 [196]

The 75% energy which does not do any useful work gets dissipated as thermal energy in gasoline engines.

Explanation:

The efficiency of any engine like gasoline engine is the ratio of work done in contrast to heat or energy provided.

Gasoline engines are internal combustion engine. The thermal efficiency is calculated of these engines.

work done or efficiency= \frac{work done}{heat absorbed}

         or heat absorbed is divided by heat used in doing work

the friction and in other forms heat gets lost.

In gasoline engine about 65 to 75 % heat gets emitted without any useful work done. The heat gets lost in friction, air turbulence, noise and work input to turn on the engine. After the dissipation of heat in it only 25% is used up by vehicle having gasoline engines.
