Choose any adaptation found in the desert (hot or cold). Describe how it helps the organism survive and/or reproduce in that biome. DO NOT CHOOSE A CAMEL HUMP
Answer:
Cactus spines
Explanation:
The cactus spines keep predators away and prevent different organisms from eating it. This helps it to survive in the desert. Another adaptation is very thick, waxy cuticle help to reduce water loss by evaporation.

I'm asking this out of personal curiosity, not for school. but it's still for educational purposes kinda, so I hope it's okay.
If a flower is wilted, but not totally dead and withered yet, is the flower dead and it's dead flower body is in the process of decomposing, or is the flower like in the flower stage of being an old person, it lived and now it's old, but not dead yet?
Here's an example of the flower stage I mean. ^-^

Punnett squares use mathematical probability to help predict the genotype and phenotype combinations in genetic crosses. Select the steps below that describe how to construct Punnett squares.
Question:
I failed to find the options, but I will post the way by which you can construct Punnett squares.
Answer and Explanation:
First, you need to know both parental individuals´ genotypes. From these genotypes, you will get all the possible gametes for each parent, following the principle of simple segregation.
Then, by using a simple square, you will make the crosses. This is:
You will locate all the possible gametes of one parent on the top of the squareYou will place all the possible gametes of the other parent on the left edge of the square.Once you have done that, you will perform the crosses. You will look for the intersection between each parent´s gametes and place all the involved alleles in the intersection-box. These are the possible genotypes, and they will be written within the square.In the attached files, you will find an example of the cross between two pure-breeding plants.
Describe the relationship between the respiratory and circulatory systems and ATP. Use the term reactants in your response.
Answer:
Cellular respiration, which generates ATP in your cells, requires oxygen to take place, also, it generates CO2 as a waste product. The respiratory system allows oxygen to diffuse into your blood, and carbon dioxide to diffuse out. The blood then carries the oxygen to the cells, so cellular respiration to continue. When the blood reaches the cells, it also takes the carbon dioxide out of the cells, and carries it to the lungs to get rid of it.

A male and a female, both with dimples, have a son without dimples. Which of Mendel's laws does this pattern of inheritance illustrate, and how do you know? AND What is the chance that a daughter of these parents would have dimples? Explain your answer.
Answer:
Explanation: Could you have drawn something different in question 3d? Explain. ... yes if both parents are heterozygous. 14 Chance no dimples. 1/4 dd 1/4 no ... If a woman is heterozygous for dimples and has 5 fingers, and a male is ... a Punnett square and calculate genotype and phenotype frequencies to explain your answer.
People also ask
According to the Mendel's Law of Segregation. Since, a male and a female, both with dimples, have a son without dimples which mean both the parents are heterozygous (Aa). since both are Aa × Aa there will be Aa, Aa, AA, aa. in which AA is dominant and aa is recessive thus the chance that a daughter of these parents would have dimple is 3/4.
What is Mendel's law of segregation?
Mendel's Law of Segregation states that a diploid organism passes a randomly selected allele for a trait to its offspring, such that the offspring receives one allele from each parent.
Thus, the chance that a daughter of these parents would have dimple is 3/4.

During meiosis, a process known as crossing over occurs. Which statement below summarizes the results of crossing over?
O Homologous chromosomes make copies of each other.
Genetic information is removed from both chromosomes.
O DNA winds up into chromosomes and genetic information is deleted.
O DNA is exchanged between homologous chromosomes, resulting in genetic variation.
Answer:the answers is B
Explanation:
Because reproduction occurs between homologous a chromosome
During meiosis, a process known as crossing over occurs. Genetic information is removed from both chromosomes.
What is meiosis ?Meiosis is the process where a single cell divides twice to produce four four haploid daughter cells which are otherwise called as gametes; It can occur in two substages such as meiosis I and meiosis II.
Humans have 46 chromosomes in every cell, where 23 chromosomes t came from one of our parents and 23 very similar chromosomes that came from the other parents.
Meiosis I consist of substages like Prophase I where nuclear envelope disintegrates, Chromosomes begin to condense, Spindle fibres appear.
Secondly Prometaphase I where Spindle fibres attach to the centromere followed by Metaphase I where The homologous chromosomes align at the equatorial plate, Anaphase I where he homologous chromosomes move towards the opposite poles.
Telophase I where Spindle fibres disappear, Cytokinesis I where the cytoplasm and the cell division result in 2 non-identical haploid daughter cells.

How does human activity impact Earth's systems such as deforestation
urbanisation desertification, erosion, air and water quality, and
allemating the flow of water?**Please use full sentences ****
Answer: Land, Water,Urbanization, and smog and acid rain.
Explanation:
Smog and acid rain are produced through similar sources, primarily vehicle and industry emissions. Though both result from human-caused air pollutants, there are chemical distinctions between the two. Though there are regulations in effect to reduce both types of pollution, they remain a threat to both human health and the environment.Smog Causes A combination of three components -- nitrogen oxides, volatile organic compounds (VOCs) and sunlight -- causes smog. Nitrogen dioxide interacts with sunlight to create nitrogen oxide and a free oxygen molecule. This interaction produces ozone, which typically turns back into nitrogen dioxide, and the cycle repeats. The addition of VOCs interrupts the cycle, however. VOCs are produced by various sources, such as paint, cleaning products and refrigerants. The VOCs prevent the breakdown of ozone, allowing it to gather near the surface of the Earth, where even more nitric oxides are produced by vehicle and industry emissions, creating the dense smog seen in large cities such as Los Angeles and Beijing.Smog Hazards The presence of ozone in the form of smog can have several negative health effects. Respiratory systems can be irritated, reducing overall lung function and triggering asthma attacks. Evidence reported by the Environmental Protection Agency also suggests exposure to ozone reduces immune system responses, especially in the lungs. These effects subside over time, but little is known about the long-term effects of repeated exposure. Vegetation also suffers from smog, as plants that take up too much ozone can be damaged in ways such as discoloration and a loss of leaves that cuts photosynthesis efficiency by up to 50 percent.

Answer: The Golgi apparatus modifies, packages, and sorts proteins for secretion or use within the cell
Explanation:
The Golgi apparatus modifies, sorts, and packages different substances for secretion out of the cell, or for use within the cell. The Golgi apparatus is found close to the nucleus of the cell where it modifies proteins that have been delivered in transport vesicles from the RER.

Explanation:
Exoskeleton
A true exoskeleton, like that found in arthropods, must be shed (moulted) when it is outgrown. ... The new exoskeleton is still capable of growing to some degree, however. Animals of the order arthropoda, like lizards, amphibians, and many other animals that shed their skin, are indeterminate growers

The atom shown below is
A. likely to form a covalent bond
o B. likely to form an ionic bond
C. not likely to form any bonds
OD. likely to form double bonds
Answer:
C. Not Likely to form any bonds
Explanation:
Assuming this atom is of neutral charge, it would be neon. We can tell as it has 10 electrons total. 2 in the first shell, 8 in the second. Noble gasses do not form bonds, generally speaking.
Furthermore, any atom, ion or not, that has a full valance (outermost shell) is generally not likely to form bonds.
