What animal group lacks true tissues and includes species that are asymmetrical

Biology
1 answer:
kondaur [170]2 years ago
8 0

The animal group which lacks true tissues and includes species which are asymmetrical is; Sponges.

<h3>Which animal group includes species that are asymmetrical?</h3>

It follows from biology of classifications that the defining characteristic of sponges includes the fact that they lack true tissues and the species are asymmetrical. Hence, the features indicated in the task content are suggestive of sponges.

if a gene has completely dominat allele and two recessive alleles how ñmany difcerent traits can these allele produce
sasho [114]

Dominance is not inherent to either an allele or its phenotype. It is a relationship between two alleles of a gene and their associated phenotypes; one allele can be dominant over a second allele, recessive to a third allele, and codominant to a fourth.

The two members used in the construction of an aircraft fuselage are joined together using a 30° fish-mouth weld. Determine the
Leya [2.2K]

This question is incomplete because it lacks the required diagram of the fuselage. Please find attached to this answer the appropriate diagram.

Answer:

The average normal stress on the plane of each weld = 66.7 psi

The average shear stress on the plane of each weld = 115.5 psi

Explanation:

From the question, we are told that two members are joined together.

From the diagram we see 800lb.

Since there are 2 members = 800lb/2

= 400lb

a) The formula for average nor umal stress on the plane of each weld = Force (in Newton)/ Cross sectional area (in inches)

From the question, we are assuming that the horizontal force = 400lb

We are given an angle of 30°

Therefore, the resultant force in Newton = F sin θ

= 400 sin 30 = 200lb

Cross sectional area = A/sin θ

= 1 × 1.5/ sin 30

= 3 in²

The average normal stress on the plane of each weld is calculated as:

200lb/3 in²

= 66.7lb/in² or 66.7 psi

b) The average shear stress on the plane of each weld = Force (in Newton)/ Cross sectional area (in inches)

Resultant force =  F cos θ

= 400 cos 30 = 346.41016151lb

Approximately = 346.41lb

Crossectional area = 3 in²

The average normal stress on the plane of each weld is calculated as:

346.4lb/3 in²

= 115.47Ib/in²

Approximately = 115.5Ib/in²

Therefore,

The average normal stress on the plane of each weld = 66.7 psi

The average shear stress on the plane of each weld = 115.5 psi

If the sequence of bases on the mrna codon is auu what would be the sequence of bases on the trna anticodon
Klio2033 [76]

Answer:

uaa

Explanation:

An anticodon is a trinucleotide sequence localized in the transport RNA (tRNA) that binds via complementary base pairing to the codon in the messenger RNA (mRNA) during protein synthesis (translation). Thus, the tRNA anticodon binds with its complementary three-letter mRNA codon during translation in order to add a specific amino acid to the growing protein. Generally, the anticodon sequence positions 34–36-nt of the tRNA that reads its cognate mRNA codon sequence via Watson–Crick base pairing.

Aliun [14]

Answer:

4. c) They result in production of diffusible second messengers

Explanation:

G-protein coupled receptors (GPCR) and steroid hormone receptors have common in the way that both result in the production of diffusible second messengers into the cytosol for further initiation of signal transduction pathways in the target cell. Hence option (c) is the correct answer.
