active transport moves mineral ions into root hair cells through cell membrane proteins. Explain how protein molecules move ions across a membrane during this process. (3marks)

Answers

Explanation:

Small and nonpolar (hydrophobic) molecules can freely pass through the membrane, but charged ions and large molecules such as proteins and sugars are barred passage.

Nonpolar and small polar molecules can pass through the cell membrane, so they diffuse across it in response to concentration gradients.

Crime-scene work often involves obtaining a DNA sample from a drop of blood to help identify persons who may have been involved. Frequently, the size of the DNA sample is extremely small, too small for easy analysis. Which of the following laboratory procedures could criminologists use to amplify the amount of DNA present?

A: Cloning and gel electrophoresis
B: Cloning and polymerase chain reaction (PCR)
C: DNA splicing and polymerase chain reaction (PCR)
D: Vector amplification and DNA splicing

Answers

Amplification of DNA is a very useful tool in the study of the human genome. DNA amplification ensures the production of multiple copies of the needed segment.

Criminologists can use Cloning and PCR to amplify the amount of DNA present...

Cloning involves creating identical copies of a particular DNA segment in study. Then amplification of the DNA using polymerase chain reaction will aid in amplifying and producing thousands of these copies of short targeted segments in minutes. This tool is very useful in ensuring the multiplication of that particular targeted sequence for analysis.

Biomes has been considered as the higher level of organization than ecosystems. Biomes are land areas formed by the influence of climate, rainfall, and latitude. There are various kinds of biomes namely desert biome, prairie biome, savanna biome, tropical forest biome, deciduous forest biome, tundra biome, and mangrove forest biome.

The Mojave Desert is a desert that comprises parts of southern California and small parts of Northern California, southwestern Utah, southern Nevada, and northwestern Arizona, in the United States.

A desert is a biome which receives very little annual precipitation. As a result of this it exhibit very hot and dry climatic conditions. The soil generally losses it's fertility which may either become compact or remain in loose form due to erosion like sand. The plants exhibit fleshy leaves so as to prevent the loss of water through transpiration.

in what generation does this population reach its carrying capacity

Answers

Answer:

The logistic population growth happens as the growth rate declines as the population exceeds the carrying power. The highest number of people in a community that the ecosystem can sustain is carrying capacity.

Explanation:

A population may reach its carrying capacity in any generation, depending on a variety of factors such as the availability of resources, predation, competition for resources, and other ecological and evolutionary processes.

What is carrying capacity?

The carrying capacity of a population is the maximum number of individuals that can be supported by a particular environment over a given time period. A population may reach its carrying capacity in any generation, depending on a variety of factors such as the availability of resources, predation, competition for resources, and other ecological and evolutionary processes.

For example, if a population of animals is introduced to a new habitat with abundant resources, it may be able to grow rapidly and reach its carrying capacity relatively quickly. On the other hand, if the population is facing competition from other species or is subjected to predation or other limiting factors, it may take longer for the population to reach its carrying capacity.

It's important to note that the carrying capacity of a population is not a fixed value, and it can change over time due to changes in the environment or the population's own characteristics. For example, if the population grows to a size that exceeds the carrying capacity of its environment, it may begin to experience negative impacts such as resource depletion, disease outbreaks, or other factors that can reduce its size and bring it back down to the carrying capacity.

Observe the cut ends of the flatworms using the hand lens or the dissection microscope immediately after cutting.
What do you see?
Are there distinct differences between the two ends?
Observe the cut ends of the flatworms over a period of several days. Do the flatworm halves continue to exhibit the same degree of difference that was seen right after they were cut in two?
What kinds of changes occur in the flatworms as they recover from having been cut in two?

Answers

The above question requires a personal answer about your experience with cutting flatworms. I can't tell you what you saw in this cut, but I'll show you what happens when it occurs.

First of all, you must understand that flatworms are worms with a great capacity for cell regeneration even if several pieces have been cut.

In this case, when a flatworm is cut in half, we can see the following events happen:

At the moment of cutting, the two ends of the flatworm body are equally shaped and are straight ends, without deformations.The ends will not be different if the cut is done accurately, but it may differ slightly.After several days, the ends will present some deformations and will lose the straight shape caused by the blade.Deformations are extremely similar and change similarly.When recovering from the cuts, each side of the flatworm body formed a new flatworm and they are no different, they are the same and they are completely recovered.

This is because the cellular regeneration of flatworms is very fast and allows any part of the flatworm's body to create exactly the same beings, as they have the same genetic makeup.

Which hormone is responsible for the development of the male secondary sex characteristics? estrogen progestin progesterone testosterone.

Answers

Answer:

It is Testosterone

Explanation:

The hormone responsible for the development of the male secondary sex characteristics is testosterone. Hence option D is correct.

What is testosterone?

Testosterone is a hormone primarily produced in the testes of males and to a lesser extent in the ovaries of females and the adrenal glands of both sexes. It is an androgen, or a hormone that promotes the development of male characteristics.

Testosterone plays a crucial role in the development of male reproductive tissues, such as the testes and prostate, as well as in the growth of muscle mass and bone density.

It is also responsible for the development of secondary sex characteristics in males, such as facial hair growth, a deepening of the voice, and the growth of Adam's apple. Testosterone also regulates sex drive (libido) and sperm production.

In females, testosterone is produced in smaller amounts and helps regulate the menstrual cycle and promote bone density.

An imbalance of testosterone levels in either males or females can lead to various health issues, including infertility, osteoporosis, and disorders of sexual development.

Hence option D testosterone is correct.

(MC)Ginny the Dog: A Hero Among HeroesHeroes come in many shapes and forms, but they all do uncommon things in unusual situations. They stand out. We've all heard stories of hero dogs that save their owners. One dog saved his owner by fighting off an alligator. Another woke his sleeping family when a fire broke out in its home. Still others rescue injured or needy people in dangerous situations. One dog even managed to call 911 when his owner suffered a seizure. But one dog, named Ginny, performed heroic acts on a regular basis, not just once or twice in unusual situations. Because of her kindness, many lives were saved.Ginny the dog was adopted by her owner from an animal shelter in 1990. Within days of bringing her home, her owner discovered that Ginny seemed to be able to find cats in distress. On her daily walks, Ginny would often find abandoned, trapped, or endangered kittens or cats that needed rescuing. In one such episode, Ginny found a group of kittens trapped in a pipe. She managed to let her owner know, by scratching and barking at the pipe, that something needed her help. Because of Ginny, all the kittens were saved.Almost daily, Ginny would find cats that needed rescuing or, in some cases, a little love. Ginny's owner reported that when Ginny saw a cat on their walks, she would pull away from her leash and run after the cat. Instead of chasing cats like most dogs, Ginny would nuzzle and lick them, giving them comfort. Because of Ginny, her owner soon found he was caring for hundreds of wild neighborhood cats. In addition, Ginny pushed her owner to adopt more than 20 cats, most of whom had permanent injuries or special needs."When we would go to the pound to drop off donations," her owner said, "Ginny always found the cat that was blind or deaf or hurt in some way. She would sit down in front of the cat's crate and not move until we brought it home."What makes a dog behave in such a kind way? Some believe Ginny had a very strong mothering instinct. But how could she tell when a cat was deaf? How did she know which cats needed love and attention? Regardless of how she did it, Ginny rescued hundreds of cats in her life and set an example we all can follow.What is the main purpose of including the story of Ginny wanting to care for blind or deaf cats?
