GIVE ME BRAINLIEST PLS LOL    

The value of the Hubble constant is estimated by measuring the redshift of distant galaxies and then determining the distances to the same galaxies (by some other method than Hubble's law). Uncertainties in the physical assumptions used to determine these distances have caused varying estimates of the Hubble constant.

Archy [21]

Answer:

Directional Selection

Explanation:

The type of natural selection that favors one of the extreme phenotypes over the intermediate and another extreme phenotype is called directional selection. Here, the extreme phenotype exhibits better survival and reproductive fitness over the other phenotypic ranges.  

In the given example, the frequency of the heat-tolerant allele in microbes is shown to increase under the conditions of higher temperatures of the water of the springs in which they live.  

When the temperature of spring water is increased, the frequency of the heat-tolerant allele is reduced and is increased again upon an increase in water temperature.

Since the natural selection favors the extreme phenotype (microbes with heat tolerance) when the spring water exhibits higher temperatures, it is directional selection.

More energy can be released from a fat molecule than from a glucose molecule because the fat molecule has more
sasho [114]

The right answer is more Chemical bonds.

Lipids are the most energetic macronutrients (as a reminder: 1 g of lipids represents 9 kcal, against 4 kcal for 1 g of carbohydrates or 1 g of proteins). Lipids are the molecules present in the fat of foods. They divide into saturated fatty acids and unsaturated fatty acids. These fatty acids can contain between 4 and 20 carbon molecules while carbohydrates contain between 3 and 6 carbon molecules.

Answer: A

Explanation: Vaccines create memory cells with a weak version of the pathogen, so when they meet that pathogen again the body can respond more quickly and more efficiently since they have already been exposed to the pathogen.
