Answer:

The correct option is <em>A. convergent evolution</em>

Explanation:

The phenomenon of evolution explains how different species might have common ancestors. This phenomenon explains that genetic variations might have led to the birth of different species from a common ancestor.

Convergent evolution can be described as a type of evolution in which similar features or traits can be observed in organisms although they may not have any genetic sequence in common. For example, sharks and dolphins look similar but they have huge differences in their genomes.

Answer:

Better healthcare

Rise in birthrate

Food security

Lack of awareness/ education

Cultural influences

Lack of family planning

Religious propagation

Malicious intent to change demographics

Immigration

For Social support

Perception of marriage & family.

Explanation:

This rapid population growth has an adverse effect on the natural resources and quality of life.

However, overpopulation has a deleterious effect on the environment due to the current lifestyle.

There would be rampant exploitation of natural resources, excess human waste accumulation, chances of epidemics, etc.

Besides, it would also lead to socio-economic problems like poverty, malnutrition, violence, corruption, etc.

Human overpopulation occurs if the number of people in a group exceeds the carrying capacity of the region occupied by that group.

Which is an example of visual data with regard to computer crime
AleksandrR [38]

"Image" is an example of visual data with regard to computer crime.

<u>Explanation:</u>

An act committed by a skilled or professional user of computers, also named as hacker who secretly browses or steals private information from a company or individual's system therefore this whole process is known as "computer crime".

Image is one of the best source or evidence in the form of visual data with respect to computer crime. Because many details can be collected or fetched out just from visual figures or pictures. It can contain codes, relatable links or some factors which can be helpful for targeting culprit.

tester [92]

Answer:

Each species has a specific identifying number of chromosomes. For example, a cat, <em>Felis catus</em>, has 38 chromosomes, while corn, <em>Zea mays</em>, has 20 chromosomes each chromosome carries specific genes that are unique to that chromosome.

Explanation:

Chromosomes vary in shape and number among living beings. For example, the bacterial chromosome is a unique circular molecule, while human beings have 46 lineal chromosomes arranged in pairs (23 pairs). The total number of chromosomes is specific to each species, and it is denoted as the "chromosomic dotation" of the species.

Genes are the hereditable units that transmit the information needed to specify traits, from parents to offspring, generation to generation. Genes are arranged in sequence in the chromosomes. A chromosome might contain hundreds of thousands of genes.

Genes vary in size and shape.  They are composed of pairs of bases, and these sequences also vary in number, producing genes of different lengths. In general, genes code for proteins. Proteins create the organism tissues and perform or carry out specific functions in the organisms, controlling almost all processes and chemical reactions.

Each chromosome carries <u>specific</u> genes that code for <u>specific </u>proteins that have <u>specific</u> functions in the organisms. Each chromosome carries information to synthesize different proteins needed to accomplish a certain function. But <u>not all chromosomes carry the same gene sequences</u>. Only homologous chromosomes carry information for the same trait, but even this information is not necessarily the same. They might have the same gene but different alleles.
