Explanation:

Answer:

The purpose of natural selection is not a conscious or intentional one, as it is not driven by a specific goal or purpose. Instead, natural selection is a fundamental process in biology that acts on heritable traits within populations over generations. It is a key mechanism of evolution.

Explanation:

The primary outcome of natural selection is the adaptation of organisms to their environment. Individuals with traits that are advantageous in a particular environment are more likely to survive, reproduce, and pass on those beneficial traits to their offspring. Conversely, individuals with traits that are disadvantageous are less likely to survive and reproduce, leading to a reduction in the frequency of those traits in the population over time.

Natural selection, therefore, acts as a filter that shapes the characteristics of populations, favoring traits that enhance an organism's survival and reproductive success in a given environment. Over many generations, this process can lead to the development of new species or the modification of existing ones, as populations accumulate adaptations that allow them to thrive in different ecological niches.

It's important to note that natural selection does not have an end goal in mind, nor does it necessarily lead to the "best" or most advanced organisms. Instead, it is a consequence of the interactions between organisms and their environment, constantly shaping and refining the traits of living beings based on their ability to survive and reproduce.

Answer:

Plant cells contain chloroplasts, but zebra cells do not

Explanation:

Chloroplasts in a plant cell are organelles that perform photosynthesis. A plant makes its energy/food from photosynthesis. Zebra cells, however, do not have chloroplasts. Therefore, zebras get their food from plants, and etc.

Plant cells contain chloroplasts, but zebra cells do not which why plants are

the primary producers in an ecosystem.

Plants produce their food through photosynthesis which involves the light

energy, oxygen and water. The light energy from the sun is trapped by the

chloroplast and used in the photosynthetic processes. Light energy is

converted to chemical energy which is used a food by the consumers.

Plant cells possess chloroplast which houses the chlorophyll while animal

cells which zebra has lacks it.

Leber congenital amaurosis (lca) is a type of autosomal recessive hereditary blindness that causes individuals with this disease to lose their vision during childhood. the pedigree below shows the inheritance of lca throughout three generations of a family. True. LCA is an autosomal recessive genetic condition that is passed on to children by parents who have an abnormal copy of the gene.

Inheritance of traits is a decrease in traits that are passed on from parents or parents to their offspring. Some of the characteristics that are passed from parent to child are hair shape, eye color, blood type, and even congenital diseases.

LCA or Leber Congenital Amaurosis is a congenital eye disorder that is present from birth. Babies from birth will lose their eyesight due to an autosomal recessive genetic condition. Babies with LCA inherit two copies of the abnormal LCA gene from both parents. A grandmother who has the normal gene marries a grandfather who has half the abnormal LCA gene So that the child will have half the abnormal or carrier genes, if the child marries someone who has half the abnormal or carrier genes, then it is certain that the third generation will have 100 percent of the abnormal LCA gene so that he will experience blindness from infancy.

Answer:

The three mechanisms of resistance crop are genetic resistance, tolerance, and avoidance. Genetic resistance is a trait that is naturally present in the crop, which makes it resistant to pests or diseases. Tolerance is the ability of the crop to tolerate pest or disease pressure without suffering major damage or yield loss. Lastly, avoidance is the ability of the crop to reduce the risk of pest or disease pressure by growing in a location or environment that is unfavorable to the pest or disease.

The speed of Lucy the Bernese Mountain Dog is 10.7 km/hr.

Speed is the time fee at which an object is transferring along a course, whilst velocity is the charge and route of an item's movement. put some other way, the pace is a scalar value, at the same time as the speed is a vector.

Speed is defined as the rate of change of function, what we understand by way of pace is the importance of using which an object is shifting, or scientifically speaking the price at which an object is converting its role per unit time is known as the speed of the item.

Given,

1 mile = 1.609 km

or 1 mile = 1.6 km (round to 1 decimal place)

∴ 2 mile = 3.2 km = 3200 m

time = 18 minutes  = 1080 second

Speed = distance / time

              = 3200m / 18 minutes

Speed in km/hr =  (3200m/1080 s) × 18/5

                          = 10.7 km/hr

Explanation:

Mutations are changes that occur in the genetic material of an individual or a population.

Mutations can be spontaneous when a variation in the DNA replication process generates a change in the genetic material, or they can be acquired by external factors, such as radiation.

When there is a change in the genetic code of individuals, this change will also be passed on to their descendants. Therefore, it is hereditary.

Analyzing the exercise, we have that the answer is option "B" is correct because mutations induced by external factors can be hereditary, so it affected the entire population A.

Tim used a chemical control method known as pesticide application.

Pesticide application involves the use of chemicals to control or eradicate pests, such as insects, fungi, and weeds. In Tim's case, he applied a pesticide to the outer layer of his crop stems to control the non-native fungus that had affected his crops. Pesticides can be applied in various forms, such as sprays, dust, and granules.

The type of pesticide used depends on the target pest and the crop being protected. While chemical control methods such as pesticide application can be effective, they also have potential drawbacks, such as the development of pesticide resistance in the targeted pest populations and the risk of harming non-target organisms and the environment.

The scenario that illustrates how the researchers could determine which of two types of bacteria exhibit "natural competence" is option (e): Incubate each alone with double-stranded DNA that contains different alleles of a chromosomal gene.

In this scenario, the researchers would incubate each type of bacteria alone with double-stranded DNA that contains different alleles of a chromosomal gene.

If one type of bacteria takes up the DNA and incorporates it into its genome, then it should display the genetic characteristics of the introduced DNA, including different alleles of the chromosomal gene. This would demonstrate that the bacteria is naturally competent, i.e. capable of taking up DNA from the environment without the need for any special treatment or processes.

By comparing the results from both types of bacteria, the researchers can determine which bacteria exhibit natural competence and are capable of taking up DNA from the environment, which can be useful for genetic manipulation and other research purposes.

Scientists show evidence that nitrogen acquired during Earth's formation came from both the inner and outer regions of the protoplanetary disk. Nitrogen is a volatile element that, like carbon, hydrogen and oxygen. Nitrogen makes up 78 per cent of the air we breathe, and it's thought that most of it was initially trapped in the chunks of primordial rubble that formed the Earth. When they smashed together, they coalesced and their nitrogen content has been seeping out along the molten cracks in the planet's crust ever since.

Water and algae are able to provide total oxygen which is enough for a person. So, 8 bathtubs of algae will fulfil one person's oxygen requirement. Thus, option C is correct.

From the analysis of the 2 equations: X = 3/4 and Y = 5/4

The equations can be solved using subtracting one of the two equations from the other.

Let's label the two equations:

Y=3x-1 .................... equation 1

Y=2-X..................... equation 2

Equation 2 can be rearranged such that:

Y = -X+2

Subtracting equation 2 from 1:

Y=3x-1

Y = -X+2

0 = 4X -3

4X = 3

  X = 3/4

Substitute X = 3/4 into any of equations 1 or 2 to determine Y.

Y = 3(3/4) - 1

Life could not exist on Earth without trees because they produce most of the oxygen that humans and wildlife breathe. Trees absorb carbon dioxide from the atmosphere and release oxygen using the process of photosynthesis. There would also be no rain without trees since trees absorb water from the soil and release it through evapotranspiration. Water vapor released through evapotranspiration is the major mechanism by which air is remoistened. Forests act as giant air filters for the world. Trees purify the air by absorbing pollutants such as sulfur dioxide and nitrogen dioxide, reducing pollution. Trees also help prevent topsoil erosion because they break the force of wind and rain on soil, their roots bind the soil, and their decayed, falling leaves are absorbed by the earth and enrich the soil. Trees conserve rainwater and reduce water runoff and sediment deposit after storms.Additionally, trees provide a supply of lumber, seeds, and fruit. Further, dead trees that fall and get
