Disruption of the ________ of cardiac muscle tissue would interfere with the heart's ability to beat in synchronous fashion.

1 answer:

3 0

Disruption in the intercalated discs in the cardiac muscles would interfere with the hearts ability to beat in synchronous manner.

The important salient features of intercalated disc are-

These intercalated disc in cardiac muscles of the heart create connections between nearby cells

The intercalated disc provides for coordinated operation of the cardiac cells and is highly specialised to facilitate the beating

Extensive folds and intercellular junctions for mechanical and electrical interactions between neighbouring cells make up the intercalated disc at the ends of muscle cells

The electrical characteristics of the cardiac muscle cells and the passage of electrical information from one region of the heart to another determine the rate at which the heart contracts and the synchronisation of atrial and ventricular contraction necessary for the efficient pumping of blood.

Two insects in the same order are in the same _______. If two insect species are in the same family, are they in the same order?

k0ka [10]

Answer:

The classification is as follow:

1-Class: Insecta

2-Order

3-Family

4-Genus

5-Species

If two insect species are in the same family they share the same order, but not in reverse mode

Two insect species have the most recent shared common ancestor if they are in the same Family since this group is more inclusive than one defined by the Order

If an insect species X and other insect species Y are in the same Family, is more likely that X and Y have the most recent common ancestor compared than the insect species Z that is in a different family

During embryo screening, a technician tests the genetic material of the embryo to find out which alleles are present.

xxMikexx [17]

Answer:

Nucleic Acid

Explanation:

NUCLEIC ACIDS are naturally occurring chemical compounds that serve as the primary information-carrying molecules in cells and makeup the genetic material. Nucleic acids are found in abundance in all living things, where they create, encode, and then store information of every living cell of every life-form on Earth.

15. When there is light, plants do which of the following biological<br> processes?<br> *

zhuklara [117]

Answer: Plants do both photosynthesis and cellular respiration.

Explanation:

All cells do cellular respiration even without light.

Honestly, photosynthesis alone would be right since the teacher didnt state the questions correctly. But you should choose both cause in the light it does both.

Different ratios occur in crosses with single gene pairs or two gene pairs. What types of ratios are likely to occur in crosses

likoan [24]

Answer:

Genotype ratio: 1, 1:1, 1:2:1

Phenotype ratio: 1, 3:1

Explanation:

Single gene pair cross is also known as monohybrid cross. This means that only one gene usually with two alleles is observed and it express one trait.

For example, if we name the gene for a certain trait with A, the possible genotypes are AA (dominant homozygous), aa (recessive homozygous) and Aa (heterozygous). Possible crosses are:

P: AA x AA

F1 : all of them are AA

The same is with aa x aa (all of the offspring are with aa genotype)

P: AA x Aa

F1: AA Aa AA Aa (genotype ratio 1:1) (phenotype ratio 3:1)

The same genotype ratio is in aa x Aa (offspring will have aa Aa aa Aa-(genotype ratio 1:1) (phenotype ratio 1:1)

P: Aa x Aa

F1: AA Aa Aa aa (genotype ratio 1:2:1) (phenotype ratio 3:1)

P: AA x aa

F1: Aa Aa Aa Aa (1)
