How does movement of the legs affect the gills of crabs?

Answers

Answer 1

Answer:

The beating or fanning movements of three pairs of maxilliped flagella in crabs and crayfish modify exhalent gill currents while drawing water over chemoreceptors on the head. They play an integral part both in signalling by distributing urine odours, and in active chemosensation.

An alkaline earth metal is more reactive than an alkali metal. *

Answers

Because of this charge increase, the atoms of the alkaline earth metals are smaller and have higher first ionization energies than the alkali metals within the same period. The higher ionization energy makes the alkaline earth metals less reactive than the alkali metals; however, they are still very reactive elements

Answer:

an alkaline

Explanation:

when valence electrons are farther from the nucleus, they are attracted less strongly by the nucleus an more easily remove from the atom .this makes the atom more reactive .this make alkaline metal with their two valence electron less reactive than alkali metal with their one valence electron

Which of the following statements best explains the general process of cellular respiration?

A: Living organisms use energy from the sun and water to create food in the form of sugar.

B: Living organisms take in oxygen and water to create food in the form of sugars and energy.

C: Living organisms breakdown sugar from food to combine with oxygen making usable energy

D: Living organisms take in oxygen and release carbon dioxide through the cells thereby providing energy.

Answers

Answer:

C. Living organisms breakdown sugar from food to combine with oxygen making usable energy.

Explanation:

Cellular respiration is about making food into energy. Since C is the only one with that aspect C can be the only answer.

The statement which best explains the general process of cellular respiration is: C: Living organisms breakdown sugar from food to combine with oxygen making usable energy.

Cellular respiration can be defined as a series of metabolic reactions which typically occur in living cells, so as to produce energy in the form of adenosine triphosphate (ATP).

Generally, high energy intermediates that can then be oxidized to make adenosine triphosphate (ATP) are created during cellular respiration.

Basically, the general process involved in cellular respiration can be represented by a single equation while using the following substances;

Glucose (Sugar).Oxygen.Carbon dioxide.Water.Adenosine triphosphate (ATP).

             [tex]Glucose + Oxygen ---> Carbon \;dioxide + Water + ATP[/tex]

In conclusion, all living organisms breakdown sugar or glucose from their food to combine with oxygen, so as to make usable energy during cellular respiration.

Use the codon table posted below (or the circular one on the first page) to determine which amino acids are assembled to make the insulin protein in both the cow and the human. Human DNA DNA CCA TAG CAC GTT ACA ACG TGA AGG AAA RNA GGU GLY Amino acid Cow DNA DNA CCA TAG CAT GTT ACA ACG CGA AGG GAC RNA Amino acid​

Answers

Answer:

Please find the complete table attached as an image

Explanation:

This task is describing the processes of transcription and translation, which are the two processes involved in gene expression. The DNA of a human and cow is given in the table of the attached image and we're asked to transcribe into a complementary RNA, and subsequently translate into an amino acid using the CODON table (genetic code).

- Transcription is the process whereby DNA is used as a template for the synthesis of RNA based on complementary base pairing i.e. A-U, G-C, T-A etc.

- Translation is the process whereby RNA transcript is used to synthesize an amino acid sequence. The mRNA is read in a group of three nucleotides called CODON, where each of this codon specifies an amino acid.

The table has been completed and attached below. Note that in the amino acids row;

GLY means Glycine

ILE means Isoleucine

VAL means Valine

GLN means Glutamine

CYS means Cysteine

THR means Threonine

SER means Serine

PHE means Phenylalanine

ALA means Alanine

LEU means Leucine

Which of the following statements describes a way in which bacteria differ from animals and plants?

Answers

Where are the options to choose from?

The BEST statement that describes how bacteria differ from animals and plants is bacteria do not have membrane-bound organelles and nuclei.

Prokaryotic cells (i.e. bacteria and Archea) have no nuclei and lack organelles.

In these cells (prokaryotic cells), the genetic material consists of a single circular chromosome localized in a region of the cytoplasm called the nucleoid.

On the other hand, eukaryotic cells (e.g., plant cells and animal cells) have their genetic material delimited by a membrane-bound organelle known as the cell nucleus.

Moreover, eukaryotic cells also have different types of membrane-bound organelles that carry out specialized functions in the cell (e.g., mitochondria, chloroplasts, Golgi apparatus, vacuoles, etc).

In conclusion, the BEST statement that describes how bacteria differ from animals and plants is bacteria do not have membrane-bound organelles and nuclei.

How are functional MRI machines being used to determine the function of different parts of the brain?

Answers

Answer:

Magnetic resonance imaging (MRI) is a technology that produces 3D images in order to assess brain activity, which is used in the diagnosis, monitoring and treatment of diseases

Explanation:

Magnetic Resonance Imaging (MRI) is a non-invasive method that generates three-dimensional (3D) images which are used for diagnostics and disease monitoring. MRI is useful to distinguish between white and grey matter in the brain, and thereby this technique can be used for the diagnosis of tumors and aneurysms which are caused by weakness in the arterial walls. Moreover, MRI is also useful to analyze the relationship between regions of the brain and cognitive processes by monitoring the neurological-psychophysiological status of an individual.
