Before carbohydrates are absorbed, __________ digest disaccharides into monosaccharides

1 answer:

3 0

Before carbohydrates are absorbed, the enzymes sucrase, maltase and lactase digest disaccharides into monosaccharides in the small intestine. Sucrase breaks down sucrose into glucose and fructose, maltase breaks down maltose into two glucose, and lactase breaks down lactose into glucose and galactose.

This is an extinct member of the Homo genus known from Pleistocene specimens found in Europe and parts of western and central As

Inga [223]

Answer:

The correct answer will be- Homo neanderthalensis

Explanation:

The closest ancestor of modern humans which evolved in the Pleistocene age which was around 7 lakh to 3 lakh years is the Homo neanderthalensis or Neanderthals.

The Neanderthals became extinct around 12,000-10,000 years ago by competitive Homo sapiens.

The specimens of Neanderthals are collected from the central and Western Asia and parts of Europe and showed approximately the same cranial capacity which is around 1450-1500 cc.

Thus, Homo neanderthalensis is the correct answer.

Which can support more weight paper or plastic grocery bags?

wariber [46]

The plastic bags held more weight compared to the paper bags. The breaking points for the plastic bags are the handles. The weak points for the paper bags are the bottom and sides of the bag. The plastic bags held more weight and could conform to different shapes and stretching characteristics.

Calculate the mass defect for oxygen-16 given this data. Round to the 5es001-1.jpg decimal place. mass of an oxygen-16 atom: 15.

Naya [18.7K]

Answer:

Explanation:

Given parameters:

Mass of oxygen atom = 15.994914amu

Mass of a proton = 1.00728amu

Mass of a neutron = 1.00866amu

Unknown:

Mass defect = ?

From the periodic table, the number of the elementary particles in a neutral Oxygen atom is given below:

Number of protons = 8

Number of neutrons = 8

Number of electrons = 8

Solution

The mass defect examines the difference between the actual mass of an atom and sum of masses of the nucleons.

The mass of an atom is concentrated in the nucleus which contains protons and neutrons. Electrons have little to no weight compared with the nucleons.

To calculate the mass defect, we first know the mass of the nucleons first:

1 proton has a mass of 1.00728amu

8 protons will weigh: (8 x 1.00728)amu = 8.05824amu

For the neutrons:

1 neutron has a mass of 1.00866amu

8 neutrons will weigh: (8 x 1.00866)amu = 8.06928amu

Mass of the nucleons = mass of protons + mass of neutrons

= 8.05824amu + 8.06928amu

= 16.12752amu

The mass defect = mass of the nucleons - mass of the atom

= 16.12752amu - 15.994914amu

= 0.132606amu ≅ 0.13261amu to 5 decimal places

Biocentrism is not considered when looking at life-centered environmental ethics

Murljashka [212]

The given statement is not true.

Biocentrism in an ecological and political sense, as well as, in an ethical perspective encompasses intrinsic value to all the living creatures. It is an understanding of how the earth functions, mainly as it associates with biodiversity.

The term biocentrism covers all the environmental ethics, which outspread the status of the moral object from human beings to all the living creatures in nature. Biocentrism witnesses each species as a component of the living biosphere.

It witnesses the outcomes of minimizing biodiversity on both the large and small scales and emphasis towards the innate values all the species exhibits towards the environment.
