Some technologies have a number of negative effects. Witch is a negative outcome of the technology of vertical farming
"Potential unemployment" is a negative outcome of the technology of vertical farming.
Explanation:
Vertical farming is an activity where food is produced on vertically oriented surfaces. Rather than single-level farming of vegetables as well as other crops, such as in a field or greenhouse, this approach generates food in vertically stacked structures that are typically built into other structures such as a skyscraper, shipping container or repurposed store.

WILL GIVE BRAINIEST
Final answer:
Mendel reached two conclusions about inherited traits: the Law of Segregation and the Law of Independent Assortment.
Explanation:
Mendel reached two conclusions about inherited traits after completing his experiments with pea plants:
Law of Segregation: Mendel observed that the two alleles for each trait separate during the formation of sex cells. This means that each parent contributes one allele for a specific trait to their offspring. For example, when a plant with yellow smooth peas is crossed with a plant with green wrinkled peas, the resulting offspring will inherit one allele for pea color (either yellow or green) and one allele for pea texture (either smooth or wrinkled).
Law of Independent Assortment: Mendel found that the inheritance of one trait is not influenced by the inheritance of another trait. For instance, the alleles that code for different traits, such as pea color and pea shape, sort independently during meiosis. This means that the expression of one trait does not affect the expression of another trait in the offspring.

Answer:
Population
Explanation:
A population is a group of living organisms of the same kind living in the same place at the same time. All of the plant and animal populations living in a habitat interact and form a community. The community of living (biotic) things interacts with the nonliving (abiotic) world around it to form the ecosystem.
We can see here that a group of the same kind of organisms living in an ecosystem is called a population.
What is ecosystem ?An ecosystem is a complex community of living organisms (biotic components) interacting with each other and their physical environment (abiotic components) within a specific geographic area. It encompasses all the organisms, their physical surroundings, and the ecological processes that occur within that particular system.
Ecosystems can vary greatly in size and scope, ranging from small microcosms, such as a pond or a forest, to vast biomes, such as a tropical rainforest or a coral reef. They can exist in terrestrial (land-based) or aquatic (water-based) environments.

energy is sc.6.L.14.2
A.fat
B.Hair
C.keratin
D.sugar
Answer:
The answer to your question is D, Sugar
Final answer:
The correct option for a carbohydrate that stores energy is D. sugar, which includes glycogen, a polysaccharide used by animals for short-term energy storage.
Explanation:
Carbohydrates are fundamental biological molecules that serve various roles, including energy storage. An essential simple sugar, glucose, shows the compact and immediate energy supply carbohydrates can provide. However, for longer-term storage, animals use a polysaccharide known as glycogen. Glycogen is made from hundreds or thousands of glucose units and is particularly abundant in liver and muscle cells. It serves as an energy reserve and is utilized when the body is fasting to maintain metabolic balance. Unlike fats or proteins, glycogen can supply the energy quickly due to its more accessible structure for enzymatic breakdown. This is why glycogen is a primary form of energy storage in animals.
The correct option from the list provided that is an example of a carbohydrate that stores energy is D. sugar. The sugars, specifically in the form of glycogen, are utilized by our bodies for short-term energy storage. This is in contrast to fats, which serve as long-term energy reserves but are not carbohydrates.
The Alligator and the Python are competing for top predator. What affect can the introduction of a non-native species have on an ecosystem?
Answer:
If a non native species got introduced then it would hurt the animals already there because there is no animals that are hunting it down. Also it would cause a imbalance in the food chain which can cause so animals to become extinct. If the animal is left unchecked then that animal can become the best in the food chain because nobody can get rid of it.

Why do we find probability of deviation in biology ? And when can the null hypothesis be accepted
Answer: probability is used to predict the chance that an event is likely to occur at a particular chosen level of significance.
Null hypothesis is accepted in biology when the p value is less than 1%, statistically, when the value of p<0.01
Explanation:
Determing the significance level is decided by the researcher, often times, scientists commonly use the 0.05, 0.01, or 0.001 probability levels as cut-off values. For instance, in the example experiment, you used the 1% probability. Thus, P ≥ 0.01 can be interpreted to mean that chance likely caused the deviation between the observed and the expected values (i.e. there is a greater than 1% probability that chance explains the data).
If instead we had observed that P ≤ 0.01, this would mean that there is less than a 1% probability that our data can be explained by chance. There is a significant difference between our expected and observed results, so the deviation must be caused by something other than chance.

How can a change to the population of one species affect an entire ecosystem?
please help!!
Changes to the population of one species can have cascading effects on other populations and the overall functioning of an ecosystem.
Explanation:Changes in one species' population can impact the entire ecosystem. For example, if the population of a predator species decreases, it can lead to an increase in the population of its prey species. This can result in a decline in the prey species' food source and eventually a decrease in their population as well.
Additionally, changes in one species can also disrupt the balance of other species that rely on or interact with it in the ecosystem. For instance, if a species suddenly becomes dominant in an ecosystem, it can outcompete other species for resources such as food, water, and shelter, leading to the decline or even extinction of those species.
This can cause a ripple effect throughout the ecosystem, impacting the abundance and distribution of other organisms, as well as the functioning of various ecological processes.
Overall, the interconnectedness of species within an ecosystem means that changes in one population can have cascading effects on other populations, ultimately shaping the structure and functioning of the entire ecosystem.

During your summer internship at a laboratory, you are given the opportunity to view a chimpanzee zygote under a microscope. You see that it has 48 chromosomes. How many chromosomes would you expect to find in a chimpanzee’s egg cell?
Answer:
If the chimpanzee’s zygote has 48 chromosomes, one would expect to find 24 chromosomes in a chimpanzee’s egg.
Explanation:
In a living organism, somatic cells are diploid and possess the full chromosome load, while gametes -sex cells- possess half of the total chromosomes, they are haploid.
The zygote of any organism that reproduces sexually results from the union of a male gamete and a female gamete, so its chromosome load is complete.
This means that if the chimpanzee has 48 chromosomes in its cells, the female sex cell - the egg - has 24 chromosomes.

Answer: a) deoxyribose sugar
b) guanine
c) adenine
d) phosphate group
Explanation: A DNA is a double stranded nucleic acid molecule. The building blocks of DNA are the nucleotides. A nucleotide is consists of deoxyribose sugar, a nitrogenous base and a phosphate group. The nitrogenous bases found in DNA are Adenine, Thymine, Cytosine and Guanine. In DNA base pairing, Adenine pairs with Thymine while Guanine pairs with Cytosine. The structure of a DNA double stranded helix is like a ladder in which the bases form the steps or rungs while the phosphate group and deoxyribose sugar form the phosphodeoxyribose backbone. Deoxyribose is a pentose, a sugar with five carbon atoms.
The two complementary base pairs in DNA are adenine (A) with thymine (T), and guanine (G) with cytosine (C), which are connected by hydrogen bonds and critical for passing genetic information during cell division.
Explanation:The two complementary base pairs of DNA are adenine (A) with thymine (T), and guanine (G) with cytosine (C). These base pairs form the ladder-like structure of the DNA molecule. Adenine and thymine are connected by two hydrogen bonds, while guanine and cytosine are connected by three hydrogen bonds. This pattern of base pairing ensures that the genetic information is accurately passed on during cell division (mitosis). The base pairs are stacked within the DNA double helix structure, which was proposed by Watson and Crick, and they are stabilised by hydrogen bonds in a specific arrangement where a purine (A or G) pairs with a pyrimidine (T or C), ensuring the uniform diameter of the helix.

Hybridization _____.
occurs frequently in nature
is the process of gene combination in a lab
usually produces offspring that cannot reproduce
creates genetically identical offspring
Answer:
The correct answer is: c) usually produces offspring that cannot reproduce.
Explanation:
Hybridization, also knowns as selective breeding, is an artificial process that involves selecting parents with specific characteristics in order to obtain an offspring with the same traits.
Hybridization is very common and has been performed by humans for thousands of years: from selective breeding crop plants, to do so with dogs in order to create more desirable breeds.
Option A is incorrect because hybridation does not occur in nature, it is an artificial process.
Option B is incorrect because hybridation often happens when the selected parents are chosen to reproduce (by a human).
Option D is correct because an important amount of hybrids are sterile (for example: mules).
Option D is incorrect as well because the offspring is not identical: it shares a combination of genes from both parents.
Answer:
usually produces offspring that cannot reproduce
Explanation:
Hybridization is the process of crossing two organisms usually of different species, genus or families but of desirable characters to produce organisms known as hybrids.
Hybrid organisms combine the characteristics of both parents and because of the difference in genetic composition of the parents, they are often sterile and hence, cannot reproduce.
Therefore, hybridization usually produces offspring that cannot reproduce.

Use the diagram to identify the parts of the nervous system. Label A is pointing to the nervous system. Label B is pointing to the nervous system.
Answer:
Label A is pointing to the peripheral nervous system.
Label B is pointing to the central nervous system.
Explanation:
The nervous system is split into two parts: the central nervous system and the peripheral nervous system.
The central nervous system (CNS) processes and coordinates information in the body. It consists of the brain and spinal cord. The brain is responsible for sensory processing and decision making; it then sends messages down the spinal cord, which transmits these messages to the rest of the body.
The peripheral nervous system (PNS) refers to the rest of the body. It transmits information to and from the CNS. It is responsible for sensory input and movement (though motor control comes from the CNS). The PNS is further divided into two systems: the somatic system, which controls volutary movements and sensory information, and the autonomic system, which regulates involuntary functions.
