Is this a good problem/observation?

Answers

Yes, but maybe limit your experiment to a certain type of plant. Because you’re changing the type of plant and the frequency it may interfere. So maybe put only one specific type of plant- so maybe say something like “I want to observe whether my wild flowers grow faster depending on the frequency I water them- once a day in comparison to once every two days, or a week.”

Explain why a relatively large forest can only support a
small number of wolves.

Answers

Answer:

below

Explanation:

It's not necessarily that a large forest can only have a small population of wolves because a larger population will not affect the ecosystem that much but it just depends on the area. One forest may have more prey than others which the wolves rely to eat and stay healthy.  So yes it would be preferred to have a smaller population but again, it doesn't hurt to have a large one either. The main problem with having a larger population of wolves can be one of two issues;

To many wolves to feed with less prey.To many wolves are going to want to fight for being the alpha in the pack.

What is photosynthesis ​

Answers

Answer:

The process by which green plants and some other organisms in the presence of sunlight to synthesize nutrients from carbon dioxide and water is called photosynthesis.

Photosynthesis is a process used by plants and other organisms to convert light energy into chemical energy that, through cellular respiration, can later be released to fuel the organism's metabolic activities.

Ricky has been struggling to sleep due to the loud noise of police sirens at night, but has noticed that the sirens have been disturbing his sleep less as he gets used to the noise. Ricky is experiencing habituation.

What is habituation?

habituation is a type of response where complete elimination of a particular response or  zero frequency of occurrence occur.

If the stimulus continues  for an additional number of trials, although no changes occur but  the response will exhibit lower levels of recovery.

Habituation is a non-associative learning in which an automatic decrease in the intensity of a response occur which is repetitive, weak stimulus, without serious consequences, for example, ignoring stimuli

Habituation defines as  the fading of the response over the course of monotonous stimulation, and sensitization refers to processes of increased response.

Ways in which biology, technology, and society are connected?

Answers

Biology and technology are connected in many ways and virtually everything will eventually affect society in some way or another. The technological advances of biology are currently having a massive effect on society due to the length of people's lives increasing. It is now common for people to live well into their 80's and 90's which is mainly due to new medications and treatments that can prevent and cure disease and infection. Most of the elderly will have a concoction of medications it is necessary for them to take on a daily basis in order for them to live happy and fulfilling lives. 50 years ago this would not have been available and they would have died much younger.

Technology and biology
The Technological advancement towards a cure for cancer seems to be getting closer every day. More and more people are now surviving cancer which was previously such a massive killer in people of all ages. Immunization is now available for every single person in developed countries so diseases are less common. Sanitation is now much better so illnesses that were previously caused by ill health, dirt and germs are now much lower because we are not exposed to such things on a daily basis.

This is all fantastic news as it living longer is something that virtually everyone wants.

Advancements and society
We want to get the most out of our lives and live a long and fulfilling life. But many countries are now struggling to cope with the increase in elderly people who need help and support from the government in order to survive. Many elderly people need people to care for them or do not have enough money to live and no way of working to provide themselves with an income. Pension plans, hospital care and home nursing care must be provided for the people who cannot afford it themselves and this is a massive drain on the economy and has a knock on effect to society and effects us all.

Animals are also victons of inhumane Forming methods. Explain the three ways how they get affected ​

Answers

Answer:
Cattle’s are fattened up and kept in horrible living conditions. Chickens often have half their beak removed because of the crowded living conditions. Pigs are kept in such horrible living conditions that they’re already dying before getting slaughtered.


Explanation:

Chickens are kept in such crowed condition that half of their beaks are removed lest they peck each other to death. Cattle are fattened up in feedlots where they are kept in crowed and filthy conditions; often their feet are rotting before they get to slaughter. Pigs too are kept overcrowded and in cages. Factory farming is NOT your grandfather’s farming methods, and those of us who object to it are not sentimental fools, as one writer here would have you believe. The animals are really abused. They are so crowded many of them would die if they were not routinely given antibiotics in their food, which why we have so many antibiotic resistant bacteria these days. Not every farmer keeps animals this way. If you like eating meat, milk, and eggs, it is possible to find them raised in healthy, humane, and sustainable ways. The products will be more expensive, but are usually tastier and of better quality. The worst abusers are surprise the big corporations pushing for profit at any cost.

Which of the following statements about eukaryotic RNA is true?
O -A small cap of extra nucleotides is added to both ends of the RNA.
O -The modified RNA molecule is transported into the nucleus.

-Exons are spliced together.

-Introns are not transcribed from DNA to RNA.

Answers

Answer:

A small cap of extra nucleotides is added to both ends of the RNA

Hope you like it

Thank you ❤️

The statement 'exons are spliced together' is TRUE. The exons are the coding regions of genes.

RNA splicing is a eukaryotic mechanism by which non-coding sequences of genes called 'introns' are removed from the precursor messenger RNA (pre-mRNA), whereas protein-coding sequences called 'exons' are spliced together.

These gene coding sequences (exons) are spliced together by a macromolecular complex known as the spliceosome.

In consequence, a pre-mRNA is converted into a mature mRNA, which is subsequently used for protein synthesis.

In conclusion, the statement 'exons are spliced together' is TRUE.

Explanation: because I had the same question too on acellus and got a right

Photosynthesis makes use of light energy while chemosynthesis is the main source of energy capture where light energy is not available.

What is photosynthesis?

It is defined as a process by which plants and other photosynthetic organisms convert the light energy in to chemical energy  through the process of cellular respiration.

Some of the energy which is converted  is stored in molecules of carbohydrates like sugar and starches  which are made up of from carbon dioxide and water . Photosynthetic organisms which can perform photosynthesis  are algae and cyanobacteria. Photosynthesis is largely responsible for producing and maintaining the content of oxygen in earth's atmosphere.

The process begins with proteins absorbing light energy  which are called reaction centers and contain a green pigment which is called chlorophyll . In plants ,these pigments are present inside organelles called chloroplasts while in bacteria they are present in plasma membrane.
