Birth rate = 35

1 answer:

6 0

Population decreases by 15.

Birth rate means more population (positive), death rate means less population (negative), immigration means more (positive), and emigration means less (negative). So, just add and subtract the appropriate numbers:

$35\ people\ born-7\ people\ die+4\ people\ enter-17\ people\ leave=\\-15\ people$

Negative 15 people means that the population decreases by 15.

Which cellular structures are the machines that build protein? where are they located?

Sergeu [11.5K]

The cellular structures that are the machines that essentially build proteins needed for the cell to grown and survive, would be the ribosomes, these small granule like organelles are found throughout the cell, whether they be freely floating in the cytoplasm of the cell or attached to the endoplasmic reticulum. They are the site for where the tRNA's complementary base pair their anticodons to the codons present on the mRNA strand.

Plants and animals that lack color are commonly called albinos. In corn plants, green (G) is dominant to albino (g). A student

Fittoniya [83]

(B) 25% GG, 50% Gg, and 25% gg

Explanation:

Given:

Green is dominant and is coded by G

Albino is recessive and is coded by g

Two corn plants that are heterozygous for color are crossed.

The heterozygous condition of the plant would be Gg.

The cross is shown in the table attached.

According to the punnett square drawn,

The genotypic ratio is 1 : 2 : 1 (GG : Gg : gg)

= 25% GG , 50% Gg , 25% gg

Phenotypic ratio = 3 : 1 ( green : albino)

= 75% green, 25% albino

Construct an explanation to predict the type of symbiotic relationship that exists between the hippo and oxpecker birds?

Allisa [31]

<h2>Answer:</h2>

<h2>The hippopotamus and the oxpecker bird are in a mutualistic and parasitic relationship. This is because the oxpecker bird gets food and protection from the hippopotamus. However, the bird gets food by making little cuts in the hippopotamus to obtain insects. This isn't entirely harmful to the hippopotamus though.</h2>

The fact that all organisms share some basic features and life processes is used by biologists to explain the idea that all life

GuDViN [60]

Answer:

c. The cells of all organisms contain DNA that is housed in a membrane-bound nucleus.

Explanation:

DNA is the genetic material found in the cells of living organisms. Among the characteristics of the DNA that makes up the genetic code, it is said to be nearly universal though. DNA is said to be the "blueprint of life".

This means that the DNA sequence that encodes protein and useful information is the same in almost all living organisms. Hence, the statement that "cells of all organisms contain DNA that is housed in a membrane-bound nucleus is the" justification that fact that all organisms share some basic features and life processes is used by biologists to explain the idea that all life.

Differentiate between dominant and recessive traits

Diano4ka-milaya [45]

Dominant trait definition. In genetics, a trait that will appear in the offspring if one of the parents contributes it. (Compare recessive trait.) Note: In humans, dark hair is a dominant trait; if one parent contributes a gene for dark hair and the other contributes a gene for light hair, the child will have dark hair ...Recessive traits can be carried in a person's genes without appearing in that person. For example, a dark-haired person may have one gene for dark hair, which is a dominant trait, and one gene for light hair, which is recessive.
