Answer:

Individuals with adaptive traits, traits that give them some advantage are more likely to survive and reproduce. Over time, these advantageous traits become more common in the population. Through this process of natural selection, favorable traits are transmitted through generations.

here are some example

Adaptatio ——A trait that improves an organism's ability to survive and reproduce in an environment

Fitness——The ability of an organism to survive and reproduce

Artificial selection——Selective breeding of organisms to promote the appearance of desirable traits in offspring

Explanation:

The kind of impact this group is having on the environment is removing garbage that could pollute and kill animals, making water cleaner, and more animal life.

When garbage is disposed of on public roads, it causes infrastructure problems and flooding. Upon reaching the rivers, it causes environmental imbalance, representing a great threat to aquatic life, in addition to contaminating the water used for human consumption, making it inappropriate and causing diseases.

With this information, we can conclude that the kind of impact this group is having on the environment is removing garbage that could pollute and kill animals, making water cleaner, and more animal life.

Answer: How many genes are copied during transcription?

The stretch of DNA transcribed into an RNA molecule is called a transcription unit and encodes at least one gene. If the gene encodes a protein, the transcription produces messenger RNA (mRNA); the mRNA, in turn, serves as a template for the protein's synthesis through translation.

The given diagram basically represents a cladogram. The correct option is D.

A cladogram is a type of diagram that depicts the evolutionary relationships between organisms.

It is a branching diagram in which the nodes represent the descendants' most recent common ancestor. The cladogram is based on the organisms' shared characteristics or traits.

These characteristics, which can be physical or genetic in nature, are used to classify organisms into clades.

Clades are groups of organisms that share a common ancestor, and they are represented on the cladogram as branches.

The organisms are more closely related the closer the branches are to each other. Cladograms are commonly used in biology to study organisms' evolutionary histories.

Thus, the correct option is D.

pH is a measure of how acidic/basic water is. The range goes from 0 to 14, with 7 being neutral. pHs of less than 7 indicate acidity, whereas a pH of greater than 7 indicates a base. pH is really a measure of the relative amount of free hydrogen and hydroxyl ions in the water.

Answer:

Since every person inherited DNA from their parents, who inherited it from their parents, and so on, a person's DNA is made up of the DNA of their ancestors. If you and another person both have the same ancestor, there's a chance that you both inherited some of the same DNA.

Answer: Look below =3

Explanation: That makes a total of 6 billion base pairs of DNA per cell. Because each base pair is around 0.34 nanometers long (a nanometer is one-billionth of a meter), each diploid cell therefore contains about 2 meters of DNA [(0.34 × 10-9) × (6 × 109)].

Each cell has 1 DNA. When it is mitosis, a piece of DNA breaks down into thing called chromosome.

The study of developmental biology has been found to show that the closely related species show similarities in embryos. Thus, the correct option is A.

Developmental biology is the branch of science which deals with the study of the process through which an organism such as an animal and a plant grows through and develops with respect to time to more evolved organisms.

Developmental biology includes the biology of regeneration, asexual reproduction of an organism, metamorphosis, and also the growth and differentiation of the stem cells which take place in the adult organisms.

Development of species accomplishes two major objectives which  generates cellular diversity as well as the order within each generation, and it also ensures the continuity of life from one generation to the next generation.

Therefore, the correct option is A.

Explanation:

The word taste, or gustation, to give its full name, refers to what is detected by the taste cells, located on the front and back of the tongue and on the sides, back and roof of the mouth. These receptor cells, or taste buds, bind with molecules from the food or drink being consumed and send signals to the brain.

The best option that describes the role of the small intestine in digestion is (C) it helps in the absorption of nutrients from food.

The small intestine is a vital part of the digestive system, and its main role is to facilitate the absorption of nutrients from the food we eat. After food is partially digested in the stomach, it enters the small intestine, where it is broken down further by enzymes secreted by the pancreas and bile from the liver.

The walls of the small intestine are lined with small finger-like projections called villi, which greatly increase the surface area available for nutrient absorption.

As food passes through the small intestine, nutrients such as carbohydrates, proteins, and fats are absorbed through the villi and into the bloodstream, where they can be transported to the cells throughout the body to be used as energy or for other purposes.

In addition to nutrient absorption, the small intestine also plays a role in the digestion of carbohydrates and proteins, and it helps to regulate the release of digestive enzymes and hormones.

Overall, the small intestine is a crucial component of the digestive system, and its proper functioning is essential for maintaining good health and well-being.

The answer is A. The population is growing.

The pyramid tells us that population is growing continuously, the growth of population is equal in both male and female population.

Population is defined as the quantity or population of people living somewhere who are a particular social, cultural, economical, ethnic, or racial category. Making decisions can be aided by knowledge of how population parameters, such as size, regional distribution, age structure, or birth and death rates, vary over time.

The pyramid is used to show the growth in population of a country or population of the city. In the pyramid the growth of population is equal in both male and female population. The pyramid shows that the population of older generation is less than the population of younger generation peoples.

Thus, the pyramid tells us that population is growing continuously, the growth of population is equal in both male and female population.

All photosynthetic organisms have chloroplasts. This is definitely false because only photosynthetic eukaryotes have chloroplasts. Thus, the correct option is 1.

Photosynthesis may be defined as a process through which green plants and some photosynthetic algae synthesize their own food with the help of carbon dioxide and water in the presence of sunlight.

Cyanobacteria are the largest and most diverse group of photosynthetic bacteria that perform photosynthesis without having the chloroplast. This type of bacterial organism is generally classified into prokaryotes.

Hence, the chloroplast is only present in the members of photosynthetic organisms that belong to the eukaryotic category.

Therefore, the statement "All photosynthetic organisms have chloroplasts" is definitely false.
