Explain why tides happen 50 minutes later each day

2 answers:

5 0

With each passing day, the high tides occur about an hour later. The moon rises about an hour later each day, too (actually, 54 minutes later). Since the moon pulls up the tides, these two delays are connected. As the earth rotates through one day, the moon moves in its orbit.

The tides occur 50 minutes later each day to allow the Earth to catch up to the moon. 24 hours and 50 minutes is the time required for the moon to return to the same spot above the Earth because the Earth is spinning on it's axis as the moon orbits the sun.

In horses, black color (B) is dominant over chestnut color (b). Find the genotype and phenotype ratios of a cross between a hybr

valentina_108 [34]

Answer:

Phenotype: 2:2 or 1:1 / Genotype: 2:2 or 1:1 / 50% probability for chestnut color

Explanation:

If we put the two horses' genotypes in a Punnett square:

B b

b Bb bb

The phenotype is describing the ending color of the offspring, where 2 of the 4 will be brown (Bb) and 2 of the 4 will be chestnut (bb), resulting in a 2:2 ratio. Genotype only refers to the alleles, where 2 of the 4 will be hybrid (Bb) and 2 of the 4 will be homozygous recessive (bb), again resulting in a 2:2 ratio. There is only a 50% chance that the offspring's phenotype will be chestnut color (bb) because the chestnut allele is recessive.

N-linked glycans are attached to proteins through N-acetylglucosamine or N-acetyl galactosamine to the amide side chain of _____

taurus [48]

Answer:

Asparagine

Explanation:

Glycans are structures made up of chains of simple sugar molecules joined together by chemical bonds. N-linked glycosylation, is the attachment of an oligosaccharide, sometimes referred to as glycan, to the amide nitrogen the amino acid asparagine (Asn) residue of a protein, in a process called N-glycosylation. This linkage is most of the time important for the structure and function of the the protein they are linked to.

In the terrestrial food web above, what would be the effect of a farmer introducing a rat poison in to the ecosystem that is tox

love history [14]

Answer:

As explained below

Explanation:

The terrestrial food web is a food web that is characterized by all land animals and is largest terrestrial food chain on earth as the farmer tends to introduce a rat poison in this food web the rat may get killed by the medicine but if the same rate may be eaten by a snake the poison that killed the rat may infect the snake.

Hence the pollutant may climb up the ladder and intoxicate the hawk that depends on small animal for prey which may be further eaten by a man or other animal like a cat may then spread this disease or the infection to other upwards in the food chain and thus the process of Biomagnification takes place in the ecosystem.

In a cross of two heterozygous parents, 25% of the offspring should have the recessive phenotype.

Degger [83]

True because if you were to do a punnet square, it would show 25% recessive 25% dominate and 75% hybrid

Drag each tile to the correct box. Arrange the layers and faults from oldest to youngest.

kaheart [24]

The answers would be:

Layer D

Layer C

Layer B

Layer A

Layer E

Fault F

If you'd like to know why, here's more about the question:

The law of superpo sition states that the lower the layer, the older the rock is.

Looking at the layers alone, we can say that D is the oldest, and C would be next, so on and so forth.

The law of cross - cutt ing relationships, on the other hand, states that a geologic event, like a fault, is younger than the layer that it goes through.

So if we look at the figure given, the fault goes through all the layers, so we can say that it is younger than all the layers.
