Answer:

1) CO₂

2) 0.2551 g

Explanation:

The balanced reactions are:

CaCO₃ + 2HCl → CaCl₂ + H₂O + CO₂

MgCO₃ + 2HCl → MgCl₂ + H₂O + CO₂

1) The gas produced is CO₂.

2) Calculate mass of CaCO₃:

(0.5236 g) (0.4230) = 0.2215 g CaCO₃

Convert to moles:

(0.2215 g CaCO₃) (1 mol / 100.1 g) = 0.002213 mol CaCO₃

Find moles of CaCO₃:

(0.002213 mol CaCO₃) (1 mol CO₂ / mol CaCO₃) = 0.002213 mol CO₂

Convert to mass:

(0.002213 mol CO₂) (44.01 g / mol) = 0.09738 g CO₂

Calculate mass of MgCO₃:

(0.5236 g) (0.5770) = 0.3021 g MgCO₃

Convert to moles:

(0.3021 g MgCO₃) (1 mol / 84.31 g) = 0.003583 mol MgCO₃

Find moles of MgCO₃:

(0.003583 mol MgCO₃) (1 mol CO₂ / mol MgCO₃) = 0.003583 mol CO₂

Convert to mass:

(0.003583 mol CO₂) (44.01 g / mol) = 0.1577 g CO₂

Total mass of CO₂:

0.09738 g CO₂ + 0.1577 g CO₂ = 0.2551 g CO₂

A woman who is a carrier for #1 hemophilia and a man that does not have the condition have children. What is the probability that they will have a child with the condition being studied? What is the gender of that child?

if the baby gets the Y chromosome from the father it will be a boy. If the boy gets his mother's X chromosome with the hemophilia gene he will have hemophilia. If he inherits his mother's other X chromosome, he will have normal blood clotting. If the baby gets the X chromosome from the father it will be a girl.

#4 A woman that is heterozygous for type A blood and a man that is heterozygous for type B blood have children. What are the possible blood types of their children?

One parent with A and another with B can produce a child with A, B, AB or O blood types.

#5 Two people are both unknowingly carriers for the cystic fibrosis gene. What is the probability that they will have children with cystic fibrosis?

If both parents are carriers there is a 1 in 4 (25 percent) chance that both will pass on the non-functioning gene, which would result in a pregnancy affected with cystic fibrosis.

#3 A woman that is heterozygous for Huntington's disease and a man that does not have the condition have children . What is the probability that their children inherit the Huntington's gene ?

Huntington's disease (HD) is what is called a dominant genetic disease. What this usually means is that a child only has a chance of getting a disease like this if a parent has it too. But parents without HD can have a child with HD. This is true of any dominant genetic disease

Answer:

b. silencing marks like H3K9 methylation; activating marks like H3K9 acetylation

Explanation:

Genomic imprinting is an epigenetic phenomenon that leads to parent-of-origin-specific monoallelic expression, thereby genes under imprinting are differentially expressed depending on their parental origin. Genomic imprinting involves DNA methylation, histone modification such as histone 3 lysine 9 methylation (H3K9) and non-coding RNA regulatory epigenetic pathways, which act together to silence one parental gene form or 'parental allele'. Maternal imprinting occurs when the maternal allele is silenced (usually caused by methylation of the maternal allele), whereas paternal imprinting occurs when the paternal allele is silenced (methylation of the paternal allele). Moreover, H3K9 acetylation is connected with active promoters (gene transcription). The imprinted genes are generally grouped in genomic regions called imprinting centers (ICs) that regulate gene expression according to the parental origin.

Viral binding to human cells is inhibited by the antiviral drug.

Well-designed antiviral drug inhibited Viral binding to human cells so that the virus can't get the place of attachment and unable to use the cell's machinery for its growth and multiplication. In this way, the humans can be prevented from having the viral infection. There are some other mechanisms also used by the antiviral drug to inhibit the growth of virus in the human body such as uncoating of virus and synthesis of new viral components.

Answer:

Humans are less aggressive as compared to non-human primates.

Explanation:

Human affiliative and aggressive behaviors are different from nonhuman primates because humans do more friendly and peaceful acts and are less aggressive in anger as compared to non-human primates which are less friendly and more aggressive in anger. Due to more aggressive behaviour of non-human primates causes more damaged to other animals and humans as compared to humans who is less damaging and aggressive.

The production of dirt is cause predominantly by living organisms

This production can be caused through emission of pollution in the form of air, water, soil, noise or e-waste.

Pollution is defined as the introduction of unwanted harmful elements in the form of release of gaseous toxic substances which result into polluting the environment.

These pollutants can be both natural and anthropogenic.

Natural pollutants are volcanic ash, river sediments

Anthropogenic pollutants are chemicals released from industries vehicular emission.

Majorly pollution are of four types- Air, Water, Soil and Noise. Recently another pollution in the form of e-waste is also prominent.

Effects of pollution on environment:

1. Biomagnification describes situations where toxins (such as heavy metals)  passes through trophic levels, becoming exponentially more concentrated in the process.

2. Carbon dioxide emissions cause ocean acidification, the ongoing decrease in the pH of the Earth's oceans as CO2 becomes dissolved.

3. The emission of greenhouse gases leads to global warming which affects ecosystems in many ways.

4. Nitrogen oxides are removed from the air by rain and affect the land which can change the species composition of ecosystems.

5. Smog and haze can reduce the amount of sunlight received by plants to carry out photosynthesis and leads to the production of tropospheric ozone which damages plants.

6. Sulfur dioxide and nitrogen oxides can cause acid rain which lowers the pH value of soil.

7. Organic pollution of watercourses can deplete oxygen levels and reduce species diversity.

Rest three options are majorly natural process.

Option B focuses on release of free nitrogen into atmosphere which is one of the important step of Nitrogen Cycle.

Option C focuses towards release of Sulfur Dioxide into atmosphere. This process is caused either naturally or anthropogenically. Thus cant blame solely the anthropogenic factor for its release.

Option C is the total natural process i.e. Climatological Process where air currents are regulated by Convection Cells and regulate based on different natural factors.

Explanation:

Answer:

The process of making food by Green plants (autotroph) is called photosynthesis. For performing photosynthesis water, sunlight and carbon dioxide are used by the plants.

They take sunlight from sun, water from soil and carbon dioxide gas from the air present around us. The leaves have small holes called stomata which allows air to enter the plant. Leaves also contains chlorophyll in them which traps sunlight and helps in making food. Roots of plants absorbs water and Minerals from the soil and transfers them leaves through stem.

The chemical equation for the photosynthesis

is -

carbon dioxide + water -> glucose + oxygen + energy

[tex] \large \boxed{\mathfrak{Answer \: with \: Explanation} \downarrow}[/tex]

Photosynthesis is the process in which green plants derive their food (nutrients and water) through the capturing of light energy (sunlight) and using it to convert carbon dioxide (CO2) and water (H2O) into oxygen (O2) and other substances (compounds) that are rich in energy. Chlorophyll a green pigment present in plants is used in this process.

Answer:

B. The chromosomes exchange genetic information.

Explanation:

Crossing over of tetrads during meiosis is very important for the exchange of genetic information.

This step of meiosis allows for each chromosome to be genetically unique and distinct from the others, creating genetic variation.

Crossing over does not double the number of chromosomes or reduce the number. The number of chromosomes stays the same.

So, the correct answer is B. The chromosomes exchange genetic information.
