Explanation:
if a plant is not green (does not contain chlorophyll) can it do photosynthesis? why or why not?
Answer:
No, it cannot carry out photosynthesis because the plant will not be able to absorb light as it does not have chlorophyll.
Explaination:
Chlorophyll in plants is used for absorbing energy from light. And, in photosynthesis, light/sunlight is one of the main factors needed, so as the plant cannot absorb light, photosynthesis can't take place.

A disease-causing bacteria successfully enters your body, making it past the first and second lines of defense. Which barrier will then act on the bacteria? chemical physical biological electrical.
Answer:
The correct answer is biological.
Explanation:
When any pathogen invades the body, it has to pass several lines of defence. The first barrier is the skin and mucous membrane which is a physical and chemical barrier. The second line of defence is the non-specific response by macrophages, neutrophils and interferon. After crossing these two barriers the third line of defence comes into action in which, the B- cells and T-cells act specifically on the pathogen and destroy it.
Answer:
[tex]\huge\boxed{\sf Biological}[/tex]
Explanation:
When first and second line of defense is passed by the bacteria, the third line of defense will come into action which is a biological barrier which includes antigen which are anti-bodies generating substances.

Construct a Venn diagram that compares and contrasts sexual and asexual reproduction.
Include the following phrases:
haploid (n)
diploid (2n)
gamete
somatic
mitosis
meiosis
cell division
chromosomes separate
genetically identical
genetically different
The Venn diagram makes a comparison between categories. Intersection: Cell division/Asexual: diploid, somatic, mitosis, genetically identica/Sexual: haploid, gamete, meiosis, chromosomes separate , genetically different.
------------
A Venn Diagram is represented as two or more circles with some degree of superposition between them. It is used to make comparisons expressing similitudes and differences between things.
Each circle represents a category -in this example, sexual and asexual reproduction-.
The superposed area is named intersection and shows things in common between the two categories.
We already know that sexual reproduction occurs by the process of meiosis, while asexual reproduction occurs by mitosis.
In superior organisms, there are two types of cells: Somatic cells and germ cells.
The somatic cells are diploid (2n), meaning that each cell has a pair of equal chromosomes. The somatic cells are all the body cells except for the sexual ones, and they reproduce by the process of mitosis.
In somatic cells, one of the sets of chromosomes is inherited from the maternal side, while the other homologous set of chromosomes is inherited from the paternal side. Hence, the number of chromosomes in these double sets of the somatic cells is diploid, 2n.
Mitosis is a process through which, from a diploid somatic cell (2n), two identical daughter diploid cells (2n) are produced.
First, occurs duplication of the cell content, and then the separation into two new cells happens.
Germ cells suffer mitosis and meiosis.
Through meiosis, germ cells produce gametes, called sperm and egg cells, through the gametogenesis process.
Gametes are haploid (n) with half the number of chromosomes that might be found in the somatic cells.
During gamete formation, the pairs of homologous chromosomes separate after crossing over. Then, sister chromatids also separate. The result is the formation of four gametes.
Each gamete has different information from the combination of homologous chromosomes belonging to the father and to the mother.
Gametes' destiny is to merge in the process of fecundation, during which a new diploid cell called zygote emerges through fertilization.
The zygote is a complete cell that suffers successive mitosis to form the new organism.

A cross country runner runs 8 km in 2 minutes. What is his speed?
The speed of the cross country runner is equal to 4 km/min.
Given the following data:
Distance = 8 km.Time = 2 minutes.To determine the speed of the cross country runner:
Speed can be defined as the distance covered by an individual per unit time and it can be measured in kilometer per minutes (km/min).
Mathematically, speed is given by the formula;
[tex]Speed = \frac{distance}{time}[/tex]
Substituting the given parameters into the formula, we have;
[tex]Speed = \frac{8}{2}[/tex]
Speed = 4 km/min.

Explanation:
Answer:
Jelly fish like a smack punch.
Explanation:
The mystery of what kind of punch a jellyfish like matched in beautifully with the show's theme - and explained why they're dubbed Scorpion. Scorpions are strongly loyal to the other members of their cyclone group. As they solve their cases, the squad surely creates a ruckus! Scorpions, like other scorpions, have very hard shells and are disliked by many people. A smack is a bunch of jellyfish, and the answer to the riddle is a clever play on the term punch. And, of course, this is what the marines called the team at the start of the show when they intended to make fun of them.

Which statement describes an important role of carbon dioxide in Earth's atmosphere?
Animals breathe carbon dioxide.
O Plants use carbon dioxide to make food.
O Carbon dioxido helps animals make proteins.
Carbon dioxide forms clouds that produce rain
Answer:Plants use carbon dioxide to make food
Explanation: Carbon-dioxide plays a very important role in sustaining life on Earth.
Plants use carbon-dioxide and water for photosynthesis in presence of sunlight and chlorophyll to produce food and oxygen.
CO₂ + H₂O → O₂ + glucose (food)
This food is consumed by the animals and oxygen is used for respiration. Animals use energy from the food to do work and exhale back carbon-dioxide.

What is the rarest eye colour in the world? Please help, it's due today.
Answer:
Green eyes
Explanation:
The production of melanin in the iris is what influences eye color. More melanin produces a darker coloring, while less makes for lighter eyes. Green eyes are the rarest, but there exist anecdotal reports that gray eyes are even rarer.
The rarest eye color in the world is green, only 2% of the population in the world have green eyes. To find out more about the list.....
1. Green eyesOnly 2% of people in the world are believed to have this eye color. It is most easily found in northern and Southern Europe and Western Asia.
2. Amber eyesThey are reddish-brown, with a golden and coppery undertone. Among the clear and beautiful eyes in the world, and according to the survey, the most iris, all eyes and beautiful in the world are according to the study, all eyes are rare and specific.
3. Red or violet eyeIt is generated by the body thanks to some genetic changes. The most common is albinism, a disease that lowers melanin levels. Because of this, the hair and eyes can be distinguished.
With this information, we can conclude that there are several eye colors, but the most rare is the color green.

Answer:
Explanation:
Antibodies have three main functions: 1) Antibodies are secreted into the blood and mucosa, where they bind to and inactivate foreign substances such as pathogens and toxins (neutralization). 2) Antibodies activate the complement system to destroy bacterial cells by lysis (punching holes in the cell wall).
If a cell that is about to divide has 22 chromosomes how many chromatids does it have? How many centromeres does it have?
44 chromatids 2 centromeres, If a cell that is about to divide has 22 chromosomes.
What are chromosomes?In the synthesis phase, the number of chromatids doubles while the number of chromosomes remains constant. Although the number of chromatids is unaffected, anaphase doubles the number of chromosomes.
Depending on whether or not the DNA has replicated and when the sister chromatids split, the chromosome changes during the cell cycle.
Meiosis I and Meiosis II are the two division cycles that occur during a meiotic cell division. Since the genetic material duplicates during the S phase of meiosis I, there will be 2n chromosomes during metaphase I.
Therefore, if a cell that is about to divide has 22 chromosomes it have 44 chromatids and 2 centromeres.

how the development of the microscope played an important part in helping to convince people that mendel was right
The microscope can be used to demonstrate the segregation of chromosomes during cell division. The law of segregation of characters is a Mendel's Law.
Each allele or gene variant is located at a specific chromosome location known as a gene locus.
The Law of Segregation indicates how one offspring receives one allele from each parent for each locus in a diploid organism.
The development of microscopy confirmed the idea that offspring receives one allele (which is located at a specific chromosome) from each parent for each gene locus.
