In order to establish the expiration date of perishable food, growth curve data must be collected. Once the microbial load is so high that it poses a hazard to human health, the food item is no longer considered safe (expired). Generally a microbial load of x50,000 bacteria/gram is considered unsafe.
Your task is to determine the microbial growth curves for MicroYo, a new brand of yogurt. The growth is determined by sampling the yogurt and growing the bacterial isolates in broth culture which is then serially diluted by a total of x10,000 and inoculated onto standard petri plates of nutrient agar. The following colony counts are measured:
Time (days) MicroYo colony count
1 1
4 1
12 2
16 4
20 7
a. 4.
b. 16.
c. 20.
d. 12.

Answers

Answer 1

Answer:

c. 20.

Explanation:

The answer is 20 because on 20 days, 7 colonies of Micro Yo occurs. The data of bacterial growth indicates that population of bacteria increases with the passage of time. This increase occurs due to good environmental conditions for bacteria that allows it to grow and increase their population. So we can say that the growth graph moves in the upward direction with the passage of time or number of days.

How do we know our current money has value? (5 points)

People talk about money a lot.

It is backed by gold.

People accept it in exchange for goods or services.

It has many security measures.

Answers

Answer:

The correct answer is - people accept it in exchange for goods and services.

Explanation:

Money is valuable because we know that it is "accepted." Money can be used to purchase goods and services even though it is no longer backed by gold. Security measures prevent counterfeiting but do not add value.

People know at that time that their current money has value when they accept it in exchange for goods or services, which is option C, as money is a medium of exchange.

The value of money is influenced by central banks. Different countries have different currencies, but the currency that is stable and has more security has more use. Money is also linked to the underlying economics, such as the ability of a country to buy and manufacture goods, thus increasing the economy. There are also many security measures, such as unique designs, special inks, holograms, etc., that are helpful for maintaining trust and confidence in the currency.

what does divine creation mean? did charles darwin agree with this idea?

The term creationism most often refers to belief in special creation; the claim that the universe and lifeforms were created as they exist today by divine action, and On the Origin of Species reflects theological views. Though he thought of religion as a tribal survival strategy, Darwin still believed that God was the ultimate lawgiver, and later recollected that at the time he was convinced of the existence of God as a First Cause and deserved to be called a theist.

explain how sexual reproduction
leads to increased variation from parent to offspring?

Answers

The process of sexual reproduction introduces variation into the species because the alleles that the mother and the father carry are mixed together in the offspring. ... A mate must be found, the egg must be fertilised by sperm, and then the offspring develop.

Sexual reproduction is the process of reproduction which leads to increased variation from parent to offspring through crossing over and fusion of gametes.

What is Sexual reproduction?

Sexual reproduction is the production of new organisms through the combination of genetic information of two individuals of different sexes (male and female). In most of the species, genetic information is carried on by chromosomes in the nucleus of reproductive cells which are haploid (n) called as gametes, which then fuse to form a diploid zygote.

Sexual reproduction results in genetic variation among different offspring. When a parent forms a gamete, only one of the chromosome from each of the homologous pair is included at random through crossing over. So, an offspring might inherit a different combination of chromosomes and alleles compared to the other offspring.

All of the following apply to estuaries EXCEPT: There provide very valuable breeding grounds for commercially important fish and shellfish. There is no salinity in estuarine ecosystems due to large supply of fresh water from a river. Plants and algae that grow here have high tolerance for changing environmental conditions like salinity and light penetration. These coastal ecosystems provide a barrier against the ocean during storms.

Answers

Answer:

There is no salinity in estuarine ecosystems due to large supply of fresh water from a river.

Explanation:

An estuary is a semi-closed body of water where fresh water and sea water meet and merge. Even though they are not a habitat to diverse species, they are very valuable breeding grounds and are one of the most productive environments. It is true that plants and algae that grow there have high tolerance for changing environmental conditions like salinity and light penetration because fluctuations happen from time to time because of the influence of the tides. And because of the partially enclosed nature of estuaries, there is provision for a barrier against the ocean during storms.

But despite the supply of fresh water, there is actually salinity in estuarine ecosystems which also varies depending on the concentration of sea water to fresh water.

Animals may undergo drug treatment to inhibit the reproduction process, and clear the parasites from their body. However, some of the parasite are resistant to drugs and may survive.

Answers

Answer:

Good environmental conditions and food availability.

Explanation:

Good environmental conditions and food availability are the factors that simulates the growth of parasite population in an animal with the passage of time. Yes, drug can reduces the population of parasites but all parasites can't be removed because some gain resistance against that chemical which allows them to survive in that environment so good environmental conditions and food availability increases population of parasite.

7.An experiment was conducted that showd the building blocks of life (amino acids) could indeed be formed by the combination of warm salt water, volcanic gases, and sparks of electricity.

Answers

Answer:

The most significant experiment performed to date on the formation of organic molecules remains that of Miller and Urey in 1952 when they sought to test the hypothesis of Oparin and Haldane that the organic building blocks of life emerged from a reducing atmosphere (Miller, 1953). Miller filled a flask with the four gaseous elements of the reductive atmosphere: methane, ammonia, hydrogen and water. He then passed electrical discharges through them to simulate lightning. After 125 h of the experiment, using the equipment available to him at the time, Miller identified several alpha amino acids contained within the residues.

1. Write a statement that uses (correctly) the terms gamete, fertilization, and zygote. (2)

Answers

Answer:

The zygote simply is the fertilized ovum or egg cell or female reproductive cell. It is the result of the process of fertilization of the fusion of the male reproductive cell (gamete) and the female reproductive cell ( gamete). In human, the zygote is the resulted cell of fertilization of the sperm and the ovum. It is diploid or 2N which means it contains two sets of chromosomes; one set from the male and the other from the female.

The gamete is the reproductive cell. There are two types of gametes; male gamete and female gamete. In human, the male gamete is called the sperm and the female gamete is called the ovum. The gamete is the last stage of the reproductive cells to be completely formed.

Fertilization is the fusion of the male gamete and the female gamete to form the zygote. Fertilization may be external as in fish or internal as in human.
