Answer:
Estuaries is a water body where freshwater from rivers and streams combines with salt water that is coming from the ocean.
Explanation:
Estuaries is a type of water body that is partially enclosed present at the coastal side where freshwater from rivers and streams combines with salt water that is coming from the ocean. Shallow estuary waters create unique habitats for organisms living there because the presence of brackish water refers to the mixture of fresh water draining from the land and salty seawater. The salinity in water change as you move from inland areas out towards the ocean because the water of inland has less salt in it while water of ocean has huge amount of salt present in it so when we move from inland to the ocean salt concentration increases in it. estuaries provide protection for inland areas by filtering pollutants, prevent shoreline erosion, flooding and storm.

how efficient both lungs and gills are in these crabs?
Answer:
In crabs, gills are more inferior to lungs in O2 uptake, but they are both quite efficient.
Explanation:
Hope this helped!
Answer:
Both are used for oxygen intake and excretion
Explanation:
In all species, the lungs were extremely effective in oxygen uptake whilst the performance of the gills was inferior. An exception to this was Gecarcoidea natalis, which has gills highly modified for aerial gas exchange; its gills and lungs were equally efficient in O2 uptake. The relative efficiencies of the lungs and gills in CO2 excretion differed between species, with the gills being the major site of CO2 loss in the more amphibious species and the lungs having an increasingly important role in the more terrestrial crabs. The presence or absence of lung portal systems was not found to correlate with either saturation rates or efferent oxygen concentrations, with both lung types being extremely efficient in O2 uptake. The lungs with portal systems showed a large increase in oxygen content in the first lacunar bed and progressively smaller increases in the next two; these lungs may, therefore, have some reserve for exercise.
One line with red flowers and the other line with violet flowers. You carry out a monohybrid cross and find that all of the F1 offspring have violet flowers, while 97 of 400 F2 offspring have red flowers.
Explain the inheritance of flower colour in this plant species.
Answer:
See the answer below
Explanation:
The inheritance of flower color in the plant species follows the simple dominance/recessive inheritance of Mendel. The red flower trait did not show up at all at F1 only for it to show up at F2. It simply means that the red flower trait is recessive while the violet flower color is dominant.
Assuming that the allele for violet flower color is designated as R while that of red flower color is designated as r. The genotype of the violet flower would be true-breeding, RR, while that of red flower color would also be true-breeding rr:
RR x rr
F1 Rr Rr Rr Rr
phenotype ratio = all violet flower color
Rr x Rr
F2 RR Rr Rr rr
phenotype ratio = 3/4 violet flower color and 1/4 red flower color
97 red flower offspring out of 400 is approximately 1/4.
Hence, the inheritance of flower color in the plant obeys a simple dominant/recessive Mendelian law with the violet color trait dominant over the red color trait.

Potassium thiosulfate (K2S2O3) is used to remove any excess chlorine from fibers and fabrics that have been bleached with that gas. The reaction is K2S2O3 + 4Cl2+ 5H2O→2KHSO4 + 8HCl a. What mass of HCl will be produced at the same time that 45.0 g of KHSO4 is produced? (5 pst) b. What mass of Cl2 is consumed along with 2.20 x 1024 molecules of H2O? (5 pts)
Answer:
The correct answer is a) 48.16 grams of HCl will be produced, b) mass of chlorine consumed is 206 grams.
Explanation:
a) The reaction given is:
K₂S₂O₃ + 4Cl₂ + 5H₂O ⇒ 2KHSO₄ + 8HCl
Based on the given information, the mass of KHSO4 is 45 grams. The moles of KHSO4 can be determined by using the formula,
Moles = given mass/Molar mass
= 45/136.16
= 0.33 Moles of KHSO₄
From the reaction it can be seen that when 2 moles of KHSO₄ is produced, 8 moles of HCl is also produced. Therefore,
2 moles of KHSO₄ = 8 moles of HCl
So, moles of HCl will be,
Moles of HCl = 8 × 0.33/2
= 1.321 moles
Now the mass of HCl is,
Mass of HCl = Moles of HCl × Molar mass of HCl
= 1.321 × 36.46
= 48.16 grams of HCl
b) It is known that 1 mole is equal to 6.023 × 10²³ molecules
In the given case, the molecules of water is given, that is, 2.20 * 10²⁴ molecules. Now let us consider that the moles of water is x.
x mole of water = 2.20 × 10²⁴ /6.022 × 10²³
= 3.653 mole of H2O
From the reaction given, it can be seen that when 5 moles of water are consumed, 4 moles of chlorine are consumed.
5 moles of water = 4 moles of chlorine
3.653 moles H₂O = x moles of Cl₂
Moles of Cl₂ = 4 × 3.653 /5
= 2.906 moles Cl₂
Now the mass of Cl₂ determined as,
Mass of Cl₂ = moles of Cl₂ × Molar mass of Cl₂
= 2.906 × 70.9
= 206 grams

How does decreasing the temperature when food is refrigerated slow decomposition and bacterial growth
Answer:
Low temperatures slow down chemical reactions, the action of enzymes, and delay or inhibit the growth and activity of microorganisms. The lower the temperature, the slower the chemical reactions, enzymatic action and bacterial growth will be.
Explanation:
Refrigeration consists of keeping the products at low temperatures, but above their freezing temperature. Refrigeration prevents the growth of microorganisms that can withstand temperatures above 45º C and many that can survive temperatures ranging from 15 to 45º C. If we lower the storage temperature of perishable foods, we will be able to significantly reduce the speed of reproduction of the vast majority of microorganisms, which cause decomposition and generate possible diseases in consumers. Refrigeration decelerates the metabolism of organic matter until it stops almost completely when we reach -18 ° C (international conservation standard for most frozen products), in addition to achieving partial or total inhibition of altering processes in food, such as certain enzymatic reactions or the metabolic degradation of proteins, thus delaying the decomposition of these.

1 and 4
3 and 4
1 and 2
2 and 3
The first two structures that combine during the process of translation are 1 and 4.
What is translation?The translation is a biological process during which the genetic codes in transcribed DNA, in the form of messenger RNA, are translated to their respective amino acids and joined together by peptide bonds to form proteins.
The steps involved in the translation process are:
mRNA binds to the small subunit of the ribosometRNA carrying methionine binds to the start codon on the mRNALarge ribosome subunit binds to complete the translation complex.In the image, mRNA is designated as 4 while tRNA is designated by 2. 1 is the ribosome while 3 is the synthesized protein.
Thus, the first two structure that binds is mRNA and tRNA. That will be 1 and 4.

Answer:
75%
Explanation:
The allele for purple flowers (capital P) is dominant.
The allele for white flowers (lowercase p) is recessive.
If one allele is capital P, it doesn’t matter if the other allele is another capital P or a lower case p, the capital P will dominate and purple flowers will show up.
The Punnett Square shows:
PP, Pp, Pp, and pp
• 3 of the offspring have at least one dominant and capital P, so purple flowers show up.
• 1 of the offspring has two lowercase and recessive alleles (p), so white flowers show up.
3/4 or 75% of the offspring will have purple flowers.
[tex]\huge\boxed{Option A}[/tex]
_____________________________________ PEA PLANT:Pea plant has purple color flowers dominant over white color flowers.
Purple flower dominant allele is P
White Flower recessive allele is p
We would get White flower pea plant only when the recessive allele is in HOMO.ZYGOUS condition
_________________________________________________________
CONDITIONS:Hom.ozygous Dominant Alleles: PP (Purple Flower)
Heter.ozygous Dominant Alleles: Pp Purple Flower)
Hom.ozygous Recessive Alleles: pp (White Flower)
____________________________________ CROSS:Whenever we cross Heterozygous Dominant(Pp) purple flower with another Heterozygous dominant (Pp purple flower), we get 75% of the flowers PHENOTIPICALLY(physical appearance) white flowered, and 25 white flowered Because as you can see in the picture,
The P1 is Pp
The P2 is Pp
When we cross them,
It has 4 offsprings,
PP Hom.ozygous Purple flower
Pp Heterozygous Purple flower
Pp Heterozygous Purple flower
pp Hom.ozygous white flower
Thus the answer is 75% as there are phynotypically 3 purple flowers present

According to Newton's first law of motion, the answer would be true.
The Newton's first law of motion states that a body will either continue to rest or in motion unless an external force acts on it.
For a body in rest, an external force would be needed to get it movingFor a moving body, an external force would be needed to increase or decrease its velocity or bring it to a rest.The body represents a mass.
