Many scientists say that there is a good reason for gaps in the fossil record. Can you explain why some extinct animals and plants were never fossilized?

Answers

Answer:

For an organism to become a fossil, it must not decompose or be eaten. This can happen if the organism either lives within or is moved to a place where it can be buried and kept from decaying. When an organism is buried quickly, there is less decay and the better the chance for it to be preserved.

If a female is sufficiently impressed with a bower, she will mate with the male who built it. This is an example of which of the five evolutionary forces

Answers

Answer:

non-random mating

Explanation:

The five different forces that influence species evolution are 1-non-random mating, 2-mutation, 3-gene flow, 4-genetic drift, and 5-natural selection. Non-random mating refers to phenotypic/behavioral differences that lead to preferential mating among individuals in a population (sexual selection). Mating behavior is a type of non-random mating pattern that includes mate choice (sexual selection) and increases reproductive fitness by increasing the chances of producing descendants ​(offspring).

based on the information on the map where are the most stable ecosystems usually found?

Answers

The correct answer is C. Near the equator.

Explanation

The image shows a world map in which there is a horizontal black line in the middle that represents the equator line and some red areas. These areas are the most stable ecosystems in the world since due to their proximity to the equator the incidence of the sun's rays is more direct. Also, in these areas, there is no weather pattern defined by seasons, but climates are defined by altitude, that is, meters above sea level. Therefore, the correct answer is C. Near the equator.

what is the process when an embryo embeds itself into the endometrium​

Answers

Answer:

Implantation is a process in which a developing embryo, moving as a blastocyst through a uterus, makes contact with the uterine wall and remains attached to it until birth. The lining of the uterus (endometrium) prepares for the developing blastocyst to attach to it via many internal changes.

Explanation:

☁️ Answer ☁️

Implantation

1. Implantation is the process where the embryo attaches to the uterine lining (endometrium) and embeds itself into the tissue. This happens around Day 5 or so of the embryo’s development.

2. Implantation is a process in which a developing embryo, moving as a blastocyst through a uterus, makes contact with the uterine wall and remains attached to it until birth. The lining of the uterus (endometrium) prepares for the developing blastocyst to attach to it via many internal changes. Without these changes implantation will not occur, and the embryo sloughs off during menstruation.

Answers

Answer: :Total distance to be travelled = 4.4 km

= 4400 m

Diameter of wheel = 70 cm = 0.7 m

Radius of wheel= 0.7 / 2 m

Circumference of wheel = 2 * pi *r

= 2* 22*0.7 / 7* 2

= 22*0.1

= 2.2 m

No. Of revolutions = Total distance / Circumference of wheel

= 4400 / 2.2

= 2000

Biology 1 Post Lab Questions: 1. Which method appear · which method appeared to have the most dramatic denaturing effect on egg albumin? Why do you think this method had a greater effect?

Answers

Hello. You have not introduced the methods used to denature the egg albumin. However, the most efficient protein denaturation method is the heating method.

The denaturation of a protein, such as albumin, occurs when an element causes the complete destruction of the protein's three-dimensional structure, in a completely irreversible way. The best way to do this is through heat. In this way, through a heating method, the heat breaks the hydrogen bonds that promote the structure of the protein, leaving it completely denatured.

What happens to species diversity WITHOUT Pisaster? *

Answers

Answer:

The starfish Pisaster ochraceus is a keystone species in the rocky marine intertidal communities off the northwest coast of North America. This predatory starfish feeds on the mussel Mytilus californianus and is responsible for maintaining much of the local diversity of species within certain communities. A keystone species is an organism that helps define an entire ecosystem. Without its keystone species, the ecosystem would be dramatically different or cease to exist altogether. This means that if the species were to disappear from the ecosystem, no other species would be able to fill its ecological niche.

Human caused reductions of biodiversity, include pollution, invasive species, and overexploitation.
O True
O False

Answers

Answer:

True

Explanation:

Development, together with globalization, drove severe changes at a global level. The natural and original environments suffered from these effects and still are.

Human beings have constantly been altering the natural ecosystems and causing irreparable damages to nature. For many decades, development involved society and technology advance over new areas unpopulated by humans.

Some of the principal human activities responsible for biodiversity loss are

the uncontrolled use of unrenewable resources, overexploitation of renewable resources; land destruction for the mining industry, farming and cattle industry, buildings, and other infrastructures; the unplanned advance of cities, and opening of new roads to connect those cities.  

All of them involving

deforestation and fragmentation of natural landscapes; water, air, and soil pollution, species loss, and reduction of biodiversity.

With globalization, transport around the world became normal. And when traveling around the world, new species are intentionally or unintentionally transported too. When these species, of animal or vegetable origin, get established in a new area, they overgrow to the point of turning invasive.

Invasive species are uncontrollable and cause severe damage in native endemic species by competing for resources. The whole ecosystem structure changes.

But there are some background glitches in the system that are the principal responsible for all the mentioned activities. Some important aspects are lacking

The respect for nature, People´s education at different levels to care and protect wildlife, Interest in keeping ancestral knowledge, Planning and previous environmental impact studies, Policies to control human activities, Caring involved government.

If, as a society, we lack these aspects, the possibilities of changing our impact on nature are far away.  

3. Most of the traits expressed in a person's phenotype are determined by Is ​

Answers

I strongly agree with the Person
Above

Most of the traits expressed in a person's phenotype are determined by is Phenotype.

What is Phenotype?

Phenotype refers to an individual’s observable traits, such as height, eye color and blood type. A person’s phenotype is determined by both their genomic makeup (genotype) and environmental factors.

An observable characteristic is simply referred to as a "phenotype." Pheno, which has the same root as the term "phenomenon," simply means "observe."

It can therefore refer to anything from a common attribute, like height or hair color, to the presence or absence of a disease. It is also an observable type of an organism.

Therefore, Most of the traits expressed in a person's phenotype are determined by is Phenotype.

Name two types of lateral pathways for the movement of sucrose from source cell into the sieve tube

Answers

Answer:

Diffusion and active transport.

Explanation:

Diffusion and active transport are the two types of lateral pathways that is responsible for the movement of sucrose from source cell into the sieve tube. Sugar molecules are moved into the sieve elements which are the phloem cells through active transport i.e. with the use of energy. The water produces turgor pressure in the sieve elements, which pushes the sugars and fluids down the phloem tubes toward the storage sites. it also moved through simple diffusion due to difference in concentration i.e. from higher to lower concentration region.

name and describe the process occurring in the nucleus wich results in the formation of an mRNA molecule.​

Answers

Answer:

The correct answer is - transcription.

Explanation:

Transcription is the process that takes place in the nucleus and the final result of the process is an mRNA molecule that encodes the information of a specific DNA sequence.

Transcription in prokaryotes is carried out in three stages.  

Initiation: Here, RNA polymerase binds to the promoter region and transiently binds to the ‘initiation factor’ to initiate transcription.

Elongation: This is the step where the RNA strand starts getting longer. RNA polymerase “walks” along one strand of DNA. For every nucleotide recognized on the DNA template, it adds a complementary RNA nucleotide to the growing RNA transcript.

Termination: Transcription stops once the RNA polymerase reaches the terminator region. At this region, the RNA transcript and the RNA polymerase, both fall off. RNA polymerase transiently associates with the ‘termination factor’ to stop transcription.
