Answers

Answer 1

Answer:

Genotype ratio Tt:tt=1:1

Phenotype ratio 1:1

Explanation:

the phenotype ratio should be 1:1 since there are 2 individuals with the dominant allele and 2 without it

The genotype ratio should be 1:1 for the same reason

Which statement is FALSE? A. Phototropism and geotropism are adaptations of plants that allow for survival. B. Tropism is the growth response of plants to their environment due to external stimuli. C. A plant's response to moonlight is phototropism while it's response to gravity is geotropism. D. A tropism that causes a plant to grow towards the stimulus is positive.

Answers

Answer:

A. Phototropism and geotropism are adaptations of plants that allow for survival.

Explanation:

Ideally, TROPISM is the growth response of plants to their environment due to external stimuli as rightly stated in this question. However, based on what stimulus the plant is responding to, there are different types of stimulus.

Phototropism (photo-light) is the response of an organism to a light source while Geotropism (geo- gravity) is the response of an organism to gravity. Hence, based on this question, a plant's response to moonlight is phototropism while it's response to gravity is geotropism.

Also, tropism can either be positive or negative depending on whether the response is towards the stimulus (positive) or away from the stimulus (negative). Therefore, the FALSE statement is "Phototropism and geotropism are adaptations of plants that allow for survival"

Why do gymnosperms and lower vascular plants lack companion cells?​

Answers

Answer:

Gymnosperms and lower vascular plants have sieve cells as their sieve elements, while sieve tubes are characteristic of flowering plants angiosperms. In gymnosperms, typical companion cells are lacking in the phloem. In gymnosperms, generally the xylem contains only tracheids. Vessels are absent.

In the sequences given, cell is the smallest unit and organ system is the largest unit.

The levels of organization the best represents the sequence from smallest to largest units is cell, tissue, organ, and organ system.

The cell represents the smallest and basic unit of all living organisms.

Tissues are aggregates of cells performing similar functions.

Organs are made of different similar tissues

Organ systems are a collection of different organs coming together as a system to perform specific functions. Examples include the respiratory system which is made up of organs like lungs, windpipe, nose, mouth, etc.

Which structure pumps out excess water and wastes?

Answers

Answer:

The contractile vacuole pumps out excess water and wastes.

Cells have a particular organelle that pumps out excess water and other wastes from the cell. Contractile vacuole serves this purpose.

The protozoan cell contains an organelle or subcellular structure called the Contractile Vacuole. It is a spherical, transparent, translucent, pulsating single-cell organelle. Previously, it was referred to as a pulsatile or pulsating vacuole. It is encased in a unit membrane, floats in the cytoplasm, and is filled with watery fluid. It is a vacuole that constricts and expels water from the cell, as its name suggests. It frequently stretches and shrinks. While water is expelled from the contractile vacuole as it expands, the contractile vacuole contracts, causing water to collect inside the organelle. The contractile vacuole is the protozoan unicellular organism's kidney. It shows the rhythmic systolic and diastolic movements.

Therefore, Contractile vacuole pumps out excess water & wastes.

For which method of determining population size is the population not aware of the sampler’s presence?

a. mark/recapture
b. direct observation
c. sampling
d. indirect observation

Answers

Answer:

The method of determining population size is the population not aware of the sampler’s presence is indirect observation.

D

The method in which the population is not aware of the sampler's presence is indirect observation (Option d).

Indirect observation refers to the collection of information obtained by other researchers in order to record it in specific informative materials (e.g., books, review/research papers, videos, etc.).

An example of indirect observation can be the record in a book of specific animal behaviors (e.g., the presence of marks on the ground).

In conclusion, the method in which the population is not aware of the sampler's presence is indirect observation (Option d).

1. A worker uses a board that is 4 m long to pry up a boulder. A small rock is used for a
fulcrum and is placed 0.5 m from the resistance end of the lever. Calculate the MA of the
I
board.

Answers

Answer:

7

Explanation:

Mechanical advantage is given by the ratio of the distance of the fulcrum from the two objects of the system.

Here the boulder is [tex]0.5\ \text{m}[/tex] from the fulcrum and the mass at the other end of the lever is [tex]4-0.5=3.5\ \text{m}[/tex] from the fulcrum.

So, mechanical advantage is given by

[tex]MA=\dfrac{3.5}{0.5}\\\Rightarrow MA=7[/tex]

So, mechanical advantage of the board is 7.

What is Evolution?

According to the idea of evolution in biology, the many species of plants, animals, and other living things on Earth descended from earlier species, and their recognizable differences are the result of changes made by subsequent generations.

More than 2 million species of organisms already in existence have been recognized and documented; many more are still undiscovered, with estimates ranging from 10 million to 30 million.

The amazing variability in size, form, and mode of existence, from tiny bacteria with a diameter of less than a millionth of a millimeter to majestic sequoias with a height of 100 meters, is as astonishing as the figures.

Therefore, negative adaptations will become more common in a population.
