Answer:

Passive transport

Explanation:

There are two ways molecules can get in and out of the cell. These processes are called Passive and Active transport.

Passive transport is the movement of molecules and materials from high to low concentration. No energy is needed for this process because it happens naturally.

This is in contrast to what Active transport is, where energy is needed because it moves the molecules or materials against the concentration gradient where they move from lower to higher concentration.

How can I remember this definition of hybridization? (Like hints)

Vaselesa [24]

Easy. A hybrid is literally a crossing of two things. A hybrid is a blueprint (genetic instructions) ready to be build.

If you can remember the hybrid and blueprint part I'm pretty sure you'll get it.

What is the biodiversity score of farmland (maize)?

Karolina [17]

Answer:

<h3>Required Answer:-</h3>

The intensification of agriculture has caused dramatic declines in farmland biodiversity (Carvalheiro et al., 2013; Senapathi et al., 2015). Since the 1990s, agricultural policies have been developed in Europe to mitigate this loss through agri-environmental schemes (AES). One AES is “sown wildflower strips”, the aim of which is to create new ecological infrastructures by sowing attractive wild flowers on arable land (a few % of the cultivated area). These ecological infrastructures fall within our definition of MIMS since they represent a massive introduction of managed species in the landscape.

The purposes of zoos and aquariums are the following four reasons. Match the definition with the term.

Igoryamba

QUESTION ONE
Here are the answers:
1. The purpose of zoo described in question 1 is EDUCATIONAL: it provides knowledge about animals' lives.
2. CONSERVATION: It protects the animals from becoming extinct.
3. RESEARCH: It is a source of animal specimens for research studies.
4.ENTERTAINMENT: people go to zoos to relax and to have fun.
QUESTION 2
The statement is TRUE.
Zoo has a lot to offer in term of educating the public and that includes the topic of biodiversity. Biodiversity refers to the variety of living organisms in the world and the relationships that exist among them. Those animals have the way they relate with other organisms. Thus, the topic of biodiversity can be treated using zoo.

What is the probability that the first offspring from the cross listed below will be heterozygous for all loci?

Tanya [424]

Answer and Explanation:

Cross: aa Bb dd Ee x AA bb Dd Ee

We can calculate the probability of getting heterozygous individuals in the progeny by using the product rule. Assuming that these four genes assort independently (events that occur independently from each other), we can infer that the F1 will have the next genotypic proportions for each gene:

1) aa x AA

F1) 4/4=1 Aa

2) Bb x bb

F1) ½ bb

½ Bb

3) dd x Dd

F1) ½ dd

½ Dd

4) Ee x Ee

F1) ¼ EE

2/4 = ½ Ee

¼ ee

So, to know what the probability is that the F1 of being heterozygous for all loci, we must multiply the respective individual probabilities of getting a heterozygous genotype, like this:

1 Aa x ½ Bb x ½ Dd x ½ Ee = 1/8 AaBbDdEe
