Answer:

A, B and AB blood groups.

Explanation:

If both a man and a woman have the blood type AB, the couple's children have A, B and AB blood groups. the reason behind these types of blood groups are the similar blood group of both male and female. According to blood type chart, a male with AB blood group married with female with the same blood group AB, it will never produce O blood group only A, B and AB blood groups.

Explanation:

Radioactive decay is the process in which the nucleus of an unstable isotope spontaneously changes, releasing particles and energy. An unstable isotope will continue to decay until it reaches the stable form of either a different isotope of the same element that is stable or a different element that is stable.

The ocean is good for animals, animals need the water and animals help the water in some type of way. And half of the people including me loves sea animals, so without the ocean, there will be no sea animals.

And the ocean is good because it produces oxygen and carbon dioxide.

Three ways by which Earth's ocean affects your life are it supplies freshwater (most rain comes from the ocean) and nearly all of Earth's oxygen. The ocean moderates the Earth's climate influences our weather and impacts human health.

It offers food, medications, minerals, and sources of renewable energy. Fishing, seafood, pleasure, and science are all supported by it. Our ocean is the first "super-highway," connecting economies and moving people and things around the world.

Animals benefit from the ocean, as they both need and contribute to the water in some form. And since I am one of the people that like sea life, there wouldn't be any sea life without the ocean.

Therefore, additionally, the ocean is beneficial since it emits carbon dioxide and oxygen.

Answer:

B

Explanation:

Erosion from a river over a very long period of time made the Grand Canyon.

Answer:

habitat destruction

increased volcanic activity

air pollution

water pollution

Explanation:

Answer: Increasing water consumption that decreases the flow of clean water from the

springs that feed the river

Explanation: Because the salamanders have less clean water, pollution becomes more of a problem, also all of the other options would help the salamanders.

The human activity that would most likely decrease the ability of the salamanders to survive is increasing water consumption, which decreases the flow of clean water from the springs that feed the river, which is the last option.

The salamander is only found in a limited area of the San Marcos River, which relies on clean water from the springs, so decreasing the flow of clean water would negatively impact the salamander's survival, as it depends on specific water conditions for survival. As water is withdrawn from the springs to meet human needs, such as agriculture, industry, or household use, less water is available, which can have a detrimental effect on the habitat that the salamander requires because of human needs.

Hence, increasing water consumption decreases the flow of clean water from the springs that feed the river, so the last option is the correct option.

The density of the average egg will be slightly greater than that of water, so it will sink. To make the egg float, we have to make the water more dense by adding salt. For 1 cup of water, adding 3 tbsp. of salt should be about enough to make the egg float.

Answer:

Atoms are the basic units comprising matter, and interact in a variety of ways.

Explanation

The most fundamental unit of matter that makes up elements is called atoms. Atoms comprise nucleus-orbiting electrons- while protons and nuetrons make up a stable nuclues. Here, the neutrons are uncharged, while the negatively charged electrons are attracted to the positively charged protons at the atom's center

The number of protons the atom determines its atomic number, and the sum of protons and neutrons determine the atomic mass.

Elements in the periodic table, are typically represented by chemical symbols- abbreviations of their atomic name. They are arranged in order of valency- atoms in the same group typically have the same number f electrons on their valence shells, and thus their physical properties behave similarly (conductivity, melting points, boiling points).

Valence electrons, on outer valence shells, also influence bonding. The atoms donate, accept or share valence electrons in order to achieve more stable atoms. Bonding between elements form molecules, that may interact with molecules to form compounds.

Answer:

B. Its temperature

Explanation:

The different states of matter are largely influenced by both temperature and pressure. The temperature has most control over water being a gas, liquid or solid ice. If the temperature is very high, the molecules in the water increases their kinetic energy. This movement causes the compound ([tex]H_{2} O[/tex]) to break its bond. Thus, it turns into a gas. On the contrary, if the temperature is very low, the molecules of the water moves closer to each other. This causes them to solidify and turn into ice.

Answer:

B) an error occurred, the mass of the reactants should equal the mass of the products.

Explanation:

The answer choices are:

A) no error occurred, some of the products are always lost as heat.

B) an error occurred, the mass of the reactants should equal the mass of the products.

C) an error occurred, the products should weigh more than the reactants.

D) no error occurred, water is not weighed when determining the weight of the products.

Solution

The basis to answer this question is the law of conservation of mass.

Any chemical reaction satisfies the law of conservation of mass: mass cannot be either created nor destroyed, so, always, the mass of the reactants equal the mass of the products.

Thus, since he measured the mass of his reactant materials to be 35g and he reported that his products weighed 32g, his data are in clear contradiction of the law of conservation of mass. So, there is an error in his results: the mass of the reactants should equal the mass of the products.

Catalysts make such a breaking and rebuilding happen more efficiently. They do this by lowering the activation energy for the chemical reaction. Activation energy is the amount of energy needed to allow the chemical reaction to occur. The catalyst just changes the path to the new chemical partnership
