Answer:
The property that could indicate that the particle is a virus is an absence of cellular machinery (option B). Explanation: Viruses are particles that are not considered to be living organisms, which is due to a complete absence of organelles or cellular functions.
Explanation:
Answer:
The correct answer is - 2 type A : 1 type AB : 1 type B
Explanation:
The pattern of the inheritance in the ABO blood group system is the example of the multiple alleles and codominance. There are three alleles in this sytem that determines what blood group would be in an indvidual that are; IA, IB, and IO. The allele IO is a recessive allele to both IA, and IB alleles whereas IA and IB are show codominance when present in heterzygous condition.
Genotype of a person with “A” blood group can be IA
IO or IA
IA but as it is given that the mother of the male with A bglood group is O blood group which means there must be a IO allele would be present in the male too so the genotype would be IAIO.
The genotype of AB blood group mother would be IAIB as shows codominance. so the cross between these woulde be as follows:
IA
IO x IA
IB
Gametes :
IA IO
, and IA IB
IA IO
IA IAIA IAIO
IB IAIB IBIO
phenotypic ratio = 2 A group : 1 AB group : 1 B group
<span>Antlion pits are often spatially aggregated even though there are potential negative effects associated with the aggregation (e.g., heightened competition and predation risk). This study investigated the possibility that a strategy leading to aggregation can be an evolutionarily stable strategy (ESS). In particular, the strategy considered was ‘decreasing relocation tendency when there are neighbors’. An individual based model showed that the strategy can be the unique ESS when the spatial distribution of prey is not completely random and antlions can learn it from their past foraging experiences. A laboratory experiment was conducted to examine the effects of the presence of neighbors and foraging success on the relocation behavior of antlion larvae. Antlions reduced their relocation tendency with respect to these factors, consistent with the predicted ESS. The results suggest that pit aggregations are formed because antlions reduce their relocation tendency when neighbors exist, and this strategy is an ESS.</span>
B) they stay the same for many generations
Answer:
amino acids
Explanation:
A protease is an enzyme capable of catalyzing the breakdown of proteins into polypeptide fragments and single amino acids, which are the building block of proteins. Proteases act by breaking peptide bonds by a process called hydrolysis, a reaction where water molecules break down peptide bonds (hydro means water and lysis means split). Proteases can be classified depending on the catalytic residue into cysteine, serine, threonine, aspartic, glutamic and metalloproteases.
