Doppler Effect is defined as the change of frequency of a sound or light wave produced by a moving source and a stationary observer. The waves when they move towards the object compresses.

The correct answer is:

Option B. lower, decreased

The Doppler effect can be explained as:

1. The listener will have the impression that the moving source is higher in the pitch as it moves away from the listener.

2. The frequency of the waves will be decreased because the time between the successive sound waves is lengthened or increased.

Therefore, the pitch will be lowered and the frequency will be decreased.

Answer:

y = -1/2x - 1

Explanation:

Slope-Intercept Form: y = mx + b

Slope Formula: [tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

Step 1: Define

(2, -2) random points

(0, -1) y-intercept

Step 2: Find slope m

[tex]m=\frac{-1-(-2)}{0-2}[/tex]

[tex]m=\frac{-1+2}{-2}[/tex]

[tex]m=\frac{1}{-2}[/tex]

[tex]m=\frac{-1}{2}[/tex]

y = -1/2x + b

Step 3: Write linear equation

y = -1/2x - 1

Explanation:

The first stage of photosynthesis is the light dependent reactions. These reactions take place on the thylakoid membrane inside the chloroplast. During this stage light energy is converted to ATP (chemical energy) and NADPH (reducing power).

The light-dependent processes make up the initial phase of photosynthesis. On the thylakoid membrane inside the chloroplast, several processes take occur. In this phase, light energy is transformed to ATP and NADPH, two chemical energies (reducing power).

The light processes of photosynthesis are carried out by a system of connected internal membranes called thylakoid membranes in a chloroplast.

Numerous proteins and chlorophyll molecules can be found in each thylakoid membrane. Clusters of chlorophyll molecules are called photosystem.

Plants use chlorophyll pigments to absorb light energy and convert it to electrons, which are subsequently transmitted down a protein chain in the thylakoid membrane.

Therefore, thylakoid membrane inside the chloroplast in  which photosynthesis form in a leaf first.

Answer:

D) Genetic engineering

Explanation:

It makes the DNA living organisms

Through the process of genetic engineering scientists can artificially change the DNA code of the organisms. Thus, the correct option is D.

Genetic engineering is also called as the genetic modification or genetic manipulation. Genetic engineering is the modification and manipulation of an organism's genes through the use of technology. It is a set of technologies which are used to change the genetic makeup of the cells, including the transfer of genes within the cells and across the species boundaries to produce improved or novel organisms.

Different types of genetic engineering include DNA extraction, through which DNA is extracted from an organism known to have the desired trait and sequence. Gene cloning includes the gene of interest which is located and copied in the DNA. Gene modification is the modification of the gene to express in a desired way through altering and replacing the gene regions.

Therefore, the correct option is D.

This question lacks options; the options are:

A) chloroplast

B) mitochondrion

C) endoplasmic reticulum

D) plasma membrane

The answer is B. mitochondrion

Explanation:

The Lungs of multicellular organisms, as described in this question, is a respiratory organ that is involved with the INTAKE of oxygen needed for cellular respiration and EXPULSION of carbon dioxide out of the body, a process called GAS EXCHANGE.

This gaseous exchange function of lungs is carried out for the process of respiration which is carried out at the cellular level by MITOCHONDRION. Mitochondrion is an organelle in eukaryotic cells associated with the cellular respiration (release of energy).

The gaseous reactants (oxygen) and products (carbon dioxide) of cellular respiration is exchanged by the LUNGS.

The cellular structure performs the same task for a cell

B. mitochondrion

The Lungs of multicellular organisms, as defined on this question, is a breathing organ this is concerned with the INTAKE of oxygen wanted for cell breathing and EXPULSION of carbon dioxide out of the body, a manner referred to as GAS EXCHANGE. This gaseous change feature of lungs is finished for the manner of breathing that is finished on the cell degree via way of means of MITOCHONDRION. Mitochondrion is an organelle in eukaryotic cells related to the cell breathing (launch of energy).

The moths adapted to the environment they were in which was heavily polluted and the spots helped it blend into the environment. It was in the UK somewhere I don't remember where though.

Explanation:

The peppered moth's evolution is an example of how air pollution during the Industrial Revolution caused directional color changes in the moth population.

The genetic basis for color was eventually discovered. Moths inherited their color from their ancestors. Eggs from light moths became light moths, whereas eggs from dark moths became dark adults.

At that time, a manifestation of industrial melanism was the rise in the number of dark-colored moths.

The moths blended in with the severely contaminated environment they were in thanks to their markings, which helped them adapt to it. Although I can't recall where, it was in the UK.

Therefore, A mutation in one moth's DNA resulted in the dark color, and the mutant gene was passed on to all the moth's progeny.

Answer:

A food chain shows the transfer of energy through a single chain of animals. For example, energy comes from the sun, a producer uses energy from the sun as food, a secondary consumer eats the primary consumer, a tertiary consumer eats the secondary consumer, and so on. An ecosystem contains many intertwining and interlocking food chains. Ecosystems contain both abiotic and biotic factors.

• Food chain is a chain of species and organisms where energy transferred from one trophic level to another.

• Level of energy transferred decreases as one move from one level to another.

• It is single directional transfer or flow of energy.

• All living species need energy for growth and survival

• Plants are consider producer since they make their food using sunlight, soil and other elements.

• Animals are consider consumers since they gain energy from eating other plants and animals.

Generally we have four Trophic level:

• Producers

• Primary consumers

• Secondary consumers

• Top consumers

Example:

• Vegetation→ Grasshoppers → Frog→ Snake → Eagle

• Plant → Frog → Snake → Peacock

• Interaction between living and non living component i.e. biotic and abiotic factor makes up an ecosystem.

• Biotic factor consists of plants, animals and decomposer.

• Abiotic factor consists of mountains, light, soil, air and water.

• Example: Forest is an terrestrial ecosystem it consist of plants and animal. A lake is an example of aquatic ecosystem aquatic plants and animals.
